You're right it's a great video and it's so nice to see the similarity with the real life. 👍

The replica is slightly quicker in straight line, but its best I can do

Hey Ridox,
Have you ever though about the sound of your cars? Because personally, the semi-racing exhaust on the Z-28 replica sounds awful, and nothing like the real thing. I know that the engine sounds in GT6 are terrible and the transmission whine almost completly covers it, but I just cant stand that sound. I did some adjusting of the parts on the replica and I think that the stock exhaust sounds most like the Z-28. I switched your semi-racing exhaust with the Isometric Exhaust manifold and changed the limiter to 98.5%. I only gained 0.4 of a Lb-ft of torque, so it performs exactly the same. I have done this to a few of your replicas that just didnt sound right, would you think of adding this to your process? Or as an alternate setup?

Did you get 7000RPM red line with stock exhaust ? The Z/28 redline at 7000RPM, and it's the combo of parts that yield closest to 481 torque, which is why I chose semi racing, beside the louder sound. Did you manage to get the gearing with stock exhaust ? Lower RPM limit will alter gearing, and some adjustments needed. The sound is often a compromise, while I also wanted better sound ( authentic ), I also need to consider torque number, redline limit and sometimes gearing. Will check the stock exhaust.

Ok no problem I'm getting used to driving without TC and no aids I took a break from GT for awhile thanks for the Camaro '14 Z/28 tune it's on Nurburgring Nordschliefe but fun I hit 178 mph on the main straight at the ring 3.910 final

GM claimed at least 180 mph top speed, Top Gear UK said it has 190mph top speed

Initial Torque : 7
Acceleration Sensitivity: 30

AERO
Rear : 20 ( Max )

View attachment 236178​

Brake Balance:
7/9 ( personal BB) or for ABS 0 wheel : 5/7, for ABS 1 - feel free to use your preferred brake balance. I recommend to run 1 click higher at the rear.

Recommended setting for DS3 user :

Steering sensitivity at +1 or +2, all aids off, except ABS 1 ( if not comfortable with ABS 0 )

with 7/9 brake balance as starting point. Go higher if preferred, 8/10 for example.

Notes :

We have ZL1 Camaro, and now an even meaner version arrived, the Camaro Z/28, a track bred racer in disguise for the street The Camaro Engineers went all out in tuning up the car, from power, chassis, driveline, tires and aero. It has only one speaker, A/C optional, no sound insulation, lightweight rear seats, thinner rear glass window and lighter engine. The wheels goes smaller in diameter size at 19" to get the car lowered, this also results in less rotating mass with lighter wheels.

Both front and rear use 305 tires / 11" wide wheel, a special tire only used on this car, super sticky Pirelli P Zero Trofeo R tire, a street legal tire with 60 treadwear rating.

For power, the Camaro received a great transplant in the form of a hand built race engine LS7 V8 from C6 Z06 with 505HP on tap and just over 480lb ft torque. It may be not much, but power is not everything. Weight has been shaved a lot from the ZL1 version ( +4120lb ), with test curb weight at 3858lb / 1750kg, about 300lb difference. I have used no fuel weight for this replica. The Camaro Z/28 has 19 US gallon fuel tank, that will be 72 liters of fuel and about 50kg weight. The weight of this replica is at 1700kg, with 53/47 distribution of the real car replicated. It's a compromise as the full curb weight can't be achieved with 53/47 distribution.

Suspension received entensive improvements, the front springs are 85% stiffer, while the rear springs are 65% stiffer than from SS springs. This equates to approximately 305.3lb/in or 5.46kg/mm for the front spring and 610.5lb/in or 10.90kg/mm rear spring. With stiffer springs, the anti roll bars are now smaller. The damper/ shocks also has been revolutionized with exclusive MultiMatic DSSV Spool Valves as used in F1, this offers exceptional damping over high and low speed. I have tuned the damper at medium stiffness to over damping, while ARB at medium to give less resistance and work with the springs better. For the alignment, I have adapted Pfadt Race Engineering Recommended Track Setup, the setup uses front/rear toe in, good amount of camber front.

For transmission, the real car uses Tremec TR6060 Close Ratio, the same ratio used on the 1LE. The gearing for this replica comes in 2 setup, one with 3.910 final as in real car, and another one with 4.210 ( adjusted final to account for 19" wheel of the real car ). The Camaro SS in GT6 comes with 20" wheel, so a higher final included to reach same max speed on each gear when 19" wheel installed ( Z/28 ).

The Z/28 uses specific build rear torsen LSD with zero preload and good amount of locking action. This is in contrast to SS and ZL1 which uses spring-loaded clutch based LSD. The design choice it to give the Z/28 very rapid turn in to hit the apex consistently, while on power out from low speed, the rear will lock, and with the 481 torque, the rear can break loose with heavy foot. The LSD also offers good balance between low speed lock up and less lock / more open on high speed range. To achieve this character, I used very low preload and medium lock, the LSD setup in GT6 gives nice balance on SH tire.

The Z/28 also received aero upgrades, from front splitter, rocker panel mouldings, rear diffuser, small rear wing and small front & rear fender lips. The Camaro SS produces 200 pound of lift at 150mph, this aero package gives some downforce at the rear to improve stability. There is also an optional Gurney Flap for the rear wing that will add more downforce. The aero package of Z/28 produces 150 pound of force at high speed.

The tire of 1LE and Zl1, Eagle F1 Supercar GII was predictable and progressive, the very high grip Pirelli Trofeo R on the other hand will be more sudden when loses traction. The Tire in GT6 is Sports Hard, the SH tire achieved similar peak cornering G's when driven at the same track as the MotorTrend Best Driver's Car 2014 : Laguna Seca.

The Camaro Z/28 won the 2014 MotorTrend Best Driver's Car, Randy Pobst, the test driver, did a great lap at Laguna Seca, posting 1:37.82. Here is a quote of what Randy has to say about the Z/28 at Laguna Seca :



I have included the lap time data, with peak G's and highest speed before braking as well as a video of the run. A replay of my run with the replica also provided, and both can be compared against the video below.

Check out the peak G's throughout the track, also particularly the last half of the track ( after corkscrew ) and top speed on each braking points. My time was 1:36.821, 00.999 quicker , this of course because a few mph difference in top speed on some braking points. The peak G's are almost dead on on most corners, the highest peak G's of the real lap is 1.72 also replicated. Watch the Youtube video and replay together I'm sure with more laps, Mr. Randy Pobst would also be in 1:36s

​

Personally, in my opinion, the Z28 tire in GT6 should be somewhere in between Comfort Soft and Sports Hard, but that's not possible.
The replay of my lap was done on 3.910 Final + Lower Ride Height + Semi Racing Exhaust, a must watch to appreciate how close the replica in terms of performance

For even closer experience, highly recommended to use stock exhaust, 4.210 Final for stock exhaust ( 400kmh/249mph max speed on transmission setup ), and Visual Ride Height Suspension Personal Alignment.



ENJOY

​

UPDATE : Thanks to @ColinH96, Added Stock Exhaust version as base ( recommended ) - Isometric Exhaust Manifold must be installed. Added 2 sets of transmission for stock exhaust, highly recommend the 4.210 Final and Visual Ride Height Suspension to be as authentic as possible to the real car. Shift point speed on each gear should closer to the video as well.

Replica has been updated, managed some few minutes of play time to check on the exhaust, massive thanks to @ColinH96 for the suggestions, added the stock exhaust setup as main/base setting + stock exhaust transmission and recommended the visual ride height suspension as base. Will update the Porsche 996 GT4 later, within a day.

@Ridox2JZGTE I've checked Camaro GT4 - At the moment the only gt4 able to catch M3 but I'll say later after more testing and making Corvette GT4

 

[TurnLeft]

Well hello mister Ridox2JzGTE, if you could possible give me a little of your time and knowledge on the subject of Replica Cars I would be much obliged.

As you know I'm trying to make a 2CV race replica, I have this little problem, at Silverstone National the best time was
1:27.390 , I'm at the limit of 45 HP, I've brought up the wight to 530kg, and I've have comfort mediums on, but my top speed is 63 mph and the leaders average at 66mph, this is with the stock transmission ( 4 speed as per rule), would it be ok to put in a 6 speed transmission to match their speed/times ? Also their is no mention about MLSD, can I tune this also? I've included the the qualifying and race times, the team to look at is Cowling/Bousfield:tup:

Thanks again my friend.

Thanks again my friend.

Using custom transmission should be okay, just render the 5th and 6th useless ( very long or very short )

Here is a little detail from 2014 Rule Book :

" 1 –28/01/2014 - Issued by BARC - 2CV PARTS.com Championship
Transmissions:
The transmission (i.e. clutch, gearbox, drive shafts) must be housed (in the case of clutch and gear train) within a standard
Citroen alloy gearbox and bell housing mounted behind the engine in the manufacturer's intended position. There shall be
four forward and one reverse gear, all of which shall be in a fully operable condition. Only the use of 2CV6 gearboxes is
permitted as detailed in 3 below.

Permitted Modifications
It is permissible to extend the gear change lever to allow 4th and reverse gears to be engaged whilst strapped in the driving
position.
The gear change must remain in the manufacturers intended position.
The two slots in the rear gearbox mounting may be closed (e.g. with welded washers).
The gear train from a drum braked gearbox may be transferred to a disc braked gearbox, provided that the gear train
complies with 3 below.
It is permissible to strengthen the gear change linkage and substitute an alternative assembly for the standard rubber
bushes, this must be mounted in the manufacturers original and unmodified position.

Prohibited Modifications
It is not permissible to intermix ratios.

Transmission and Drive Ratios
1st 5.202 (19/25 X 14/31 X 14/25 = 0.0465)
2nd 2.656 (19/25 X 23/26 X 14/25 = 0.3764)
3rd 1.785 ( 14/25 = 0.5600)
4th 1.315 (19/25 = 0.7600)
Rev as first gear Final Drive 4.125 (8/33)

For Ride Height :

Ground Clearance must comply with the requirements of the MSA Yearbook. For the purposes of this regulation the shock
absorbers and exhaust are considered to be part of the car and are subject to the same ground clearance (40 mm
minimum)

For Weight :

Cars shall have a minimum weight of 655kg, inclusive of driver at all times during and at completion of practice and racing.

I think the rear differential should stay stock ( open diff ), as gearbox are mandated to be stock 2CV6 type. There are aftermarket LSD for 2CV, but I can't find infos if they can be used in the race.

Thank you, no worries, mate, life must have been busy

I get only 502PP/406BHP.

Which power setup is it ? BOP Reduction 390HP ? I've oil changed my car .

I have been testing the Porsche 996 GT4, the details of the specs were sketchy, so I have to use GT3 996 power as base line, and use best lap time at Spa as reference and weight from SRO GT4 BOP for 997 Porsche. Even with 1400+kg, the Porsche 996 / RUF RGT is damn fast, at less then 400HP, it beaten 2:36s at Spa

The Porsche 996 / Ruf RGT was not supposed to be published as I felt the car is a bit on the wild side and tricky to drive on the limit. A friend of mine, asked for a tune with 500PP limit on the RGT. He tried a certain 500PP tune from here, done by the most famous tuner ( what he said ). He also said the car was weird for a RR layout, floaty with rear hanging, like a soap box on sticky tire when turning and drive like an FR car with engine at the rear I can't even imagine what he's saying, too vague / weird to drive a RR car like that.

So, I gave him the replica tune, and he said the car drive like an old school RR, but fun and more involving, the RR DNA is there, controlled pendulum effect, stable turn in, massive rear grip on exit and responsive steering even at low speed, but can still punish the driver when the rear pushed too far.

I hope the Porsche 996 GT4 will not be a nightmare It did 2:14s flat at Silverstone GP and 2:34s at Spa, both were not really a good clean lap

Thank you, no worries, mate, life must have been busy

👍 Kind of, unexpected problems and other stuff... Happy to building again great replicas!!

Which power setup is it ? BOP Reduction 390HP ? I've oil changed my car .

I have been testing the Porsche 996 GT4, the details of the specs were sketchy, so I have to use GT3 996 power as base line, and use best lap time at Spa as reference and weight from SRO GT4 BOP for 997 Porsche. Even with 1400+kg, the Porsche 996 / RUF RGT is damn fast, at less then 400HP, it beaten 2:36s at Spa

So I should change the oil? You'll correct the tuning description?

Nooo, I changed it after I posted the replica, it didn't have oil change. Not sure what happen, I only have racing exhaust installed.

Then something's wrong. I have as well the Racing Exhaust and the weight is correct.

[TurnLeft]

Using custom transmission should be okay, just render the 5th and 6th useless ( very long or very short )

Here is a little detail from 2014 Rule Book :

" 1 –28/01/2014 - Issued by BARC - 2CV PARTS.com Championship
Transmissions:
The transmission (i.e. clutch, gearbox, drive shafts) must be housed (in the case of clutch and gear train) within a standard
Citroen alloy gearbox and bell housing mounted behind the engine in the manufacturer's intended position. There shall be
four forward and one reverse gear, all of which shall be in a fully operable condition. Only the use of 2CV6 gearboxes is
permitted as detailed in 3 below.

Permitted Modifications
It is permissible to extend the gear change lever to allow 4th and reverse gears to be engaged whilst strapped in the driving
position.
The gear change must remain in the manufacturers intended position.
The two slots in the rear gearbox mounting may be closed (e.g. with welded washers).
The gear train from a drum braked gearbox may be transferred to a disc braked gearbox, provided that the gear train
complies with 3 below.
It is permissible to strengthen the gear change linkage and substitute an alternative assembly for the standard rubber
bushes, this must be mounted in the manufacturers original and unmodified position.

Prohibited Modifications
It is not permissible to intermix ratios.

Transmission and Drive Ratios
1st 5.202 (19/25 X 14/31 X 14/25 = 0.0465)
2nd 2.656 (19/25 X 23/26 X 14/25 = 0.3764)
3rd 1.785 ( 14/25 = 0.5600)
4th 1.315 (19/25 = 0.7600)
Rev as first gear Final Drive 4.125 (8/33)

For Ride Height :

Ground Clearance must comply with the requirements of the MSA Yearbook. For the purposes of this regulation the shock
absorbers and exhaust are considered to be part of the car and are subject to the same ground clearance (40 mm
minimum)

For Weight :

Cars shall have a minimum weight of 655kg, inclusive of driver at all times during and at completion of practice and racing.

I think the rear differential should stay stock ( open diff ), as gearbox are mandated to be stock 2CV6 type. There are aftermarket LSD for 2CV, but I can't find infos if they can be used in the race.

Thanks, I missed that second page with the rest of the technical information, funny thing, they mention 530kg max car weight , and 655kg max weight with driver, I guess my weight is now 125kg (275lbs), I don't think my girlfriend is going to like this. One other little thing that confuses me, they say 40mm minimum height, from what I understand the lowest value I get in the suspension setting is 95 in., ( I guess that in. = inches ) , that gives me 2413mm (if I didn't make a mistake that is ), I guess I have no worries about breaking that rule. You want to know what I would really like for PD to put as an update, is a 3 or 4 or 5 speed fully adjustable gearbox, wouldn't that make your life a little easier, sure would make mine right now (maybe also a 13 speed gearbox for my schwimmwagen). I've reread the tech specs and I too can't find anything about adjustable MLSD, so mom's the word, will do with out it. Again thanks a thousand carburetors for your help, I'll probably try to finish this one next week, I've got a few reviews I want to do (guess who?)plus I'm going to put my Schwimmwagen, Sambabus, my other 2cv, and a Karmann Ghia on some serious drug tests, will try seeing the effect of the (M)LSD on these low powered cars and try to find a way of using the data logger to get some viable data for future tunings, take care of yourself and if you drive in the rain put your wipers on.

​

Notes :

Saleen S281 has been sold for years in America This is 2007 model year S281E replica.

The Saleen S281E has 550HP power with 525 ft lb torque, the replica has been built as close as possible with 550HP/523ftlb. The real car weight is 1642kg or 3620lbs with 53/47 distribution, while in GT6 I can get the weight, but the distribution is at 56/44.

The S281E is equipped with N2 RaceCraft suspension upgrade from Saleen. With coilover springs + damper all around, but still retain the rear live axle with panhard rod. I have set the spring rate according to real life N2 RaceCraft spring rate, and tuned the damper + ARB to gives good balance. Several suspension alignment have also been provided. Try them all, and see which one fits you.

Gearing uses Tremec T56 in real life, a 6 close ratio speed manual with 4.1 final, the ratios are similar to the T56 used on Pontiac GTO and Holden Monaro. I have also included a 2nd set of ratio, Tremec TR6060 close ratio with better spread. The LSD is Saleen MaxGrip Speed Sensitive LSD, I tried to simulate the performance using lower preload and medium lock on acceleration + low lock on braking.

The Saleen S281E was tuned and tested at Tsukuba, Silverstone GP and Nordschleife. At Tsukuba, it can lap an easy 1:05s on comfort soft.


ENJOY

Hey Ridox,
I just did the same sound modification to the Saleen because the Racing exhaust doesnt sound anything like the real Saleen Mustang.
My new tune has
Engine Tuning Stage 3
Sports Computer
Stock Exhaust
Exhuast Manifold
Sports Cat.
Stock Intake
No Supercharger

Limiter at 99.2%

This torque is up by 4 lb-ft from your replica, but the sound is so much nicer.

The only other thing that I have done is go back to the stock transmission because you cant use the custom trans with the H-pattern on my G-27.

 

[Ridox2JZGTE]

I think most 2CV will have more than 530kg minimum weight without driver, the 530kg figure was more likely example of what 2CV is capable of :

"With 35-45HP and a car weighing only 530Kg the cars can still do 90 mph."

Ride height in GT6 is ground clearance in mm I have built several replicas like Lexus ISF in which I used manual data, and the numbers are very closely matched ( in mm ). I'm still curious though, 40mm is very low

Will look into this Is this Saleen Dark Horse ?

Then something's wrong. I have as well the Racing Exhaust and the weight is correct.

Will double check

 

[ColinH96]

It was the 281 Extreme, the 550Hp one. However Im sure that the Dark Horse is a similar case.

 

[Ridox2JZGTE]

It was the 281 Extreme, the 550Hp one. However Im sure that the Dark Horse is a similar case.

I have edited the replica, fixed the error ( it had oil change, supposed to be no oil change ), checked the Dark Horse, is has oil change, I don't think it can get close to real life torque with stock exhaust, torque will be too high ( also tried with no oil change car )

@danbojte : Fixed the BMW M3 GT4 Chrome Line, I must have posted the figure when it has worn engine.

Notes :

The BMW M3 GT4 is one of the competitor in European GT4 Cup. The car is very competitive for it's price range and has full support from BMW Motorsport division.

The replica is set at 420HP / 1380kg base setup. The 2009 BOP figure has also been included at 390HP. After 2010, the BOP power has been set at 420HP.

Suspension has been setup to replicate real life ride height, with springs aimed to counter the effect of lower front. This offers good balance in handling, very stable, but might need some trail braking to get the most of the car.

LSD is 2 way, with medium preload, and optional 1.5 way also included. The 1.5 way offers better turn in response. Gearing is based on stock 6 speed, still uses H pattern and the final has been changed to 4.44 for better performance.

The BMW M3 GT4 was tuned and tested at Tsukuba, Willow Springs, Silverstone GP and Red Bull Ring. At Silverstone GP, it can lap in 2:13s range on 1st lap

The BMW M3 GT4 is one of the competitor in European GT4 Cup. The car is very competitive for it's price range and has full support from BMW Motorsport division.

The replica is set at 420HP / 1380kg base setup. The 2009 BOP figure has also been included at 390HP. After 2010, the BOP power has been set at 420HP.

Suspension has been setup to replicate real life ride height, with springs aimed to counter the effect of lower front. This offers good balance in handling, very stable, but might need some trail braking to get the most of the car.

LSD is 2 way, with medium preload, and optional 1.5 way also included. The 1.5 way offers better turn in response. Gearing is based on stock 6 speed, still uses H pattern and the final has been changed to 4.44 for better performance.

The BMW M3 GT4 was tuned and tested at Tsukuba, Willow Springs, Silverstone GP and Red Bull Ring. At Silverstone GP, it can lap in 2:13s range on 1st lap


ENJOY

Hey Ridox, if you have a couple of mins (ok, 8:40 lol) could you take a look at this:



I'm starting to get the hang of tuning, and i feel good working on FF cars at the moment. This is a test for a serie i had on my mind. It's 275hps 1400kg on comfort soft tyres. I've tried to tune in your style; no nonsense values that just work ingame and a realistic feeling. What i'm wondering is how you would judge the tune's (car) behaviour.

btw the video doesn't make justice to the work it takes to keep the car running fast on comfort tyres the drive was actually a blast one of the funniest rides i had in long time and with a car noone ever uses

Brake Balance:
4/3 ( personal BB) or for ABS 0 wheel : 3/2, for ABS 1 - feel free to use your preferred brake balance. I recommend to run 1 click lower at the rear.

Recommended setting for DS3 user :

Steering sensitivity at +1 or +2, all aids off, except ABS 1 ( if not comfortable with ABS 0 ) with 4/3 brake balance as starting point.

Notes :

The Porsche 996 GT4 is a rather unique race car, it's rare, only one team uses it at BritCar GT Championship.

Details are hard to come by, I only have drivers name, best lap times at 2 tracks that can be replicated in GT6 ( Spa and Brands Hatch Indy ), base power figure and the rest I have to adapt from SRO GT4 Porsche BOP spec ( 1411kg, 415PS )

As it's not a really replica, I included a variety of choices of power and gearing setup. For power, there are 3 setup, GT4 Base ( 380PS/375HP ), GT3 Cup ( 390HP ) and SRO BOP ( 415PS/409HP ), all are on the same weight from SRO BOP, 1410kg - the closest I can get with max ballast, 1 kg less. Weight distribution is at 39/61 like the 996 GT3 spec. With lowest power - GT4 Base, the replica can easily beaten the real life lap record at Spa and Brands Hatch Indy. GT4 Base and GT3 Cup spec uses isometric exhaust manifold, while SRO BOP uses intake tuning instead ( remove exhaust manifold ). Racing exhaust used on all setup.

Suspension uses Eibach Springs and Sachs 2 Way Damper, the 997 GT4 uses Moton Race Damper. I set the springs to the stiffest possible, with damper, ARB and alignment to give good traction/balance with the rear heavy layout.

The GT4 Base uses G96/91 ratio from GT3 Cup 1999-2004 ratio spec ( medium to high speed ), I have also included variety of ratios used by 996 GT3 cars ( RSR, Cup ) The G96/97 6 Speed is best for low to medium speed track, while the G97/63 Sequential and Hewland offers better shift speed/performance with triple plate clutch.

LSD is Paul Guard 50/80 Race Setup, with medium preload, this offers great traction, stability and responsive around mid corner. The base spec GT3 Cup LSD has 40/60 Setup, I also included this as an option.

I tuned and tested the Porsche 996 GT4 at Spa, Silverstone GP, Brands Hatch Indy, Laguna Seca and Red Bull Ring. The real life best lap at Spa Francorchamps 2009 BritCar GT Rd 3 was 2:36.164, at Brands Hatch Indy 2009 BritCar GT Rd 7: 49.415. Both can be beaten with GT4 Base 375HP + Hewland Ratio

Here are the lap times of the test run :
Silverstone GP : 2:14.076
Brands Hatch Indy : 0:49.094
Spa Francorchamps : 2:34.287

I also included replays of all 3 lap times for reference.


ENJOY

I will

thanks mate i tried some of your works and i appreciate your opinion

 

[Ridox2JZGTE]

Hey Ridox, if you have a couple of mins (ok, 8:40 lol) could you take a look at this:



I'm starting to get the hang of tuning, and i feel good working on FF cars at the moment. This is a test for a serie i had on my mind. It's 275hps 1400kg on comfort soft tyres. I've tried to tune in your style; no nonsense values that just work ingame and a realistic feeling. What i'm wondering is how you would judge the tune's (car) behaviour.

btw the video doesn't make justice to the work it takes to keep the car running fast on comfort tyres the drive was actually a blast one of the funniest rides i had in long time and with a car noone ever uses

I watched the whole lap Nice driving, consistent and smooth. I saw that the car performed well on the 1st half, right through the foxhole and before the 1st carousel. From visually looking at the car negotiating the bumps, and dips, especially at foxhole, the front spring are stiff, with the rear probably just as stiff or a bit lower. The front seems to have a good damping on high speed, but suffers slightly when under heavy braking. The rear seems under damped when hitting big bumps, not reacting quick enough ? I see that the car also tend to rotate when least expected, do you use lots of negative toe ?

For the last half of the track, after the 1st carousel, the car tend to struggle on lower speed corners, maybe ARB at the rear is very high ? Some oversteer on entry and medium speed correction. Do you use high compression and low extension on the rear spring ? Looks like the car has good turn in when not pushed too hard. Anyway, those are just my observation, not really expert opinion Hope I don't make all the wrong guesses

 

[azidahaka]

this was... interesting mate actually what couldn't be easily seen is that the car has a distinct continuons 4 wheels controlled slide around all corners, the setup is not finished but it's so fun that i'm unsure i want to change it it's so lively when you drive it if you know what i mean lol

btw some struggling is my driving, i'm used to racing tires and just lately started dealing with harder compounds... Until 3-4 months ago i would almost race RS only

Controlled slides must be extreme tune like those on current FITT Focus ST tunes

 

[azidahaka]

if you are interested i'll send it up to you.... i have no clue if the time at nurb is good or not for the car/tune, but it was certainly a great fun in a never used car
