Yes, thanks. I manage to tame it, just there's no pleasure. 👍

No plans for the Aston Vantage GT4? Even with the V12 I don't think that it would be too far off from real times.
or how bout a Mazda Mx5 gt4. Can that Be replicated? I noticed it on a different replica tune thread but never heard of a miata gt4 car before.
Yes, thanks. I manage to tame it, just there's no pleasure. 👍
Thanks Orido. I'll apply the changes when I'll get home. 👍Hi Dan, I had a short play time on GT6, about 15 minutes or so, I checked my Aston Martin, I have built a simple version of Vantage GT4, seems okay even with V12 engine instead V8 like it should
As for the Evora, drove a couple of laps, it does have brake lift oversteer on the 1st turn at Silverstone GP.
Here is a quick tweak I did that might help you :
Lower rear spring rate to 15.18kg/mm - 850 lb/in
Lower rear ARB to 3
Lower rear brake balance to 3
This will reduce rotation slightly under braking and high speed cornering, but still rotate well on low speed and medium speed as well as a bit more stable. The rest are the same as replica posted.
Hey Ridox, I am trying to build a real life setup for the '06 Aston Martin DB9 and I found this chart about the factory alignment but there are no units, I was hoping that you could you interpret it for me.

Great racing! 👍
@Ridox2JZGTE
talking about the '86 gt4 replica, i would love if you could adjust the setup for the '12 Base model; i can't get the feeling of being in a racecar with the 86 '13 normal car's interior >_> the base model interior would be perfect for the car
I didn't touched it anymore.Nice!! I have been busy past a few days, will find time this weekend to post the Camaro and Corvette GT4. How's the Evora going ?
...
I didn't touched it anymore.
Neither, yet.Touch the settings or touch the car ( as in driving it )
Thanks Orido. I'll apply the changes when I'll get home. 👍
Edit : It's a big improvement. I'll tweak it tomorrow furthermore I hope. What's sure is ABS 0 (0/0) on wheel. 👍
Neither, yet.
I missed this
I see, gotcha

Steering sensitivity at +1 or +2, all aids off, except ABS 1 ( if not comfortable with ABS 0 ) with 6/4 brake balance as starting point.
Notes :
It all started with a message from a fellow member Danbojte Then I saw the red car in action at the track ( a picture of it ) and I realized I have the car in the garage, sitting there in stock form with over 200km from lapping Bathurst.
The Ferrari 458 Italia GT3 was born It's a loosely based on real life car, not a full replica so to speak, as detailed information are hard to find, but I do have some of the most important information at hand. I spent a good hour or so to find the needed information, and tuning/testing around 2 hours
First is power and weight, there are many level of power and weight for this car, due to various competition rules and balancing purposes. This build is a base model, a middle ground if you want to call it. Power is at 550CV or 543HP with 550Nm/405lb-ft of torque and 2750lbs or 1247kg. To achieve the torque, I have to use isometric exhaust manifold to bring the torque up at 406.5
I scoured the net for technical information of 458 GT3, I found some that I used here.
Suspension is based on INTRAX Black Titan ARC ( Anti Roll Control ) 4 Way Damper, a great damper kit that received great praise when tested on a 458 GT3 at Spa Francorchamps. Springs are EIBACH ERS, with a set of 3 options front and back :
Front
120-60-280 N/mm
120-60-300 N/mm - Installed
120-60-320 N/mm
Rear
170-60-180 N/mm
170-60-200 N/mm - Installed
170-60-220 N/mm
As these springs rate are way too high and not available in GT6, I used the middle range ratio 300/200 and adapt it on GT6, the front are 1.5 times harder than rear. I used 16.67kg front and 11.49kg rear and it works so well. With damper setup to maintain excellent traction in all conditions, entry, mid corner, or exits, you name it, this 458 GT3 does it well.
For transmission, the real car uses HEWLAND 6 speed gearbox, I managed to get rare information on the homologated gearing. Not sure if the final is fixed in real life, but in GT6 you are free to lower the final for higher top speed. The homologated gearing is setup to take advantage of the 458 GT3 engine peak power and torque, shift point is at 8700rpm ( 1st shift light ) and usable range from 7500-9000rpm. Again, real life spec works wonder in GT6, spot on !! Ignore the 7th gear for the sake of authenticity, if you find the car hitting the limiter on 6th, lower the final, I would recommend 3.725 for Bathurst ( 310+kmh top speed at conrod )
LSD, the real Ferrari 458 uses E-Diff, I read that it uses 2 way with capability to reduce locking rate under braking So, I fine tuned the LSD in GT6, using high preload commonly used on racing cars, and high locking rate on accel and brake. The value has been optimzed, a click up or down of value would give substantial changes Higher gives better traction and response at a cost of tightness, while lower will give more freedom of movement. I set both at 45, this is perfect for most situation. You can fine tune the 458 GT3 behavior just by using LSD - rough guide :
Static initial/preload at 28.
accel 48 / brake 45 ( neutral entry, very tight mid corner to exit )
accel 47 / brake 45 ( neutral entry, tight mid corner to exit )
accel 46 / brake 45 ( neutral entry, moderate mid corner to exit )
----accel 45 / brake 45 ( neutral all around - used on the tune )
accel 45 / brake 48 ( very tight entry, neutral mid corner to exit )
accel 44 / brake 44 ( slightly loose entry, slightly loose mid corner to exit ) - running lower will make the car more loose.
The tuning and testing process was done at Tsukuba, Brands Hatch GP, Silverstone GP, and Bathurst.
This base model managed an easy 2:04.9xx at Bathurst during testing, 53.1s at Tsukuba, 1:24s at Brands Hatch GP, and 2:01s at Silverstone GP
This Ferrari 458 GT3 is very quick at 570PP, with it's deficit in aero/down force, it excels in mechanical grip, balance, traction and acceleration even on higher speed region Red makes it even faster
ENJOY
Update : Added optional custom rear wing + wheels selection and detailed spring rate value under notes.
Wow, just brilliant.
Having used a few of your tunes only recently on the new A-Spec seasonals I used this one and fell in love instantly. It's just amazing, perfect handling and great under braking.
I tried up til now the Maserati MC Stradale, the Paul Walker R34, the F40 EU and the 599XX and this is by far the best one so far.
The Maserati struggled with understeer at Silverstone, the R34 also had an understeer problem at Laguna Seca, the F40 I struggled getting it to be stable enough and under braking on the first corner at Laguna Seca it was quite hard to keep it from spinning out unless I braked in a straight line and before turning in, and the 599XX again had some understeer at Bathurst, but then I got the 458 out with this tune and instantly found the brakes to be so good, then handling was even better, I love it. Really well done. (It's better than Praiano's tune )
As I test out more I shall let you know how I get on, but so far the 458 is the best.
Thank you Some of the cars that have understeer, I may be able to give some tweak suggestion when I play and drive them again next time. For the F40, which spring rate combo do you use ? ABS 1 or 0 ? Altering the BB can help a lot with stability and reducing understeer on entry The easiest tweak for understeer issue is lowering the LSD initial by 2 until you find a value that suits you best.
The 458 GT3 indeed is a great car, one of the main reason is that it has quite decent front and rear aero which gives it great handling potential. It was also a tune of the week on weekly rewind long ago. If you like the 458, maybe you will like some other GT3 replicas like the Mclaren MP4-12C, Viper GT3R and Camaro GT3.
For the F40 I used the setup listed at the bottom - 12.00 12.00 springs and track ride height with same BB's. ABS 1 and Sports Medium because it was a little bit more stable. I just found on the first corner if I went down to first gear it would just spin as I turned, but if I downshifted before turn-in it was fine. Not sure if it was due to trail braking or downshifting, but on the corkscrew it was fine in 1st.
As for the others, yes I shall reduce the Initial slightly - with the Maserati I could get it to loosen up on entry, but it just involved chucking it into the corners, but the R34 felt good other than strange gears and some understeer on entry especially, but I can fix that.
Yes, that's the plan - I want to try all your race replicas to be honest - the Gallardo, the GT86, the MP4, Aston, Viper, Ford GT and Camaro, but I'm just going down your list at the moment, and then hit the Italia and had to say how good it was.
That's what I've got so far :Hi Dan, ...
As for the Evora, drove a couple of laps, it does have brake lift oversteer on the 1st turn at Silverstone GP.
Here is a quick tweak I did that might help you :
Lower rear spring rate to 15.18kg/mm - 850 lb/in
Lower rear ARB to 3
Lower rear brake balance to 3
This will reduce rotation slightly under braking and high speed cornering, but still rotate well on low speed and medium speed as well as a bit more stable. The rest are the same as replica posted.
For the F40, try 6/4 BB and lower rear damper extension to 4, or if with lower rear ext damper, the car more sluggish to rotate on exit, increase the rear ext instead to 6 or 7
That's what I've got so far :
Suspension :
75/100
11.60/15.18
6/7
8/10
3/3
1.2/2.5
-0.04/0.16
Brake Discs & Calipers :

Notes :
My 1st built among many of GT4 cars that are on the works. I was fascinated by this car as I read on GT Academy winners racing it at Endurance races in Europe. A few years back it was 350Z, but from a couple of years ago, 370Z is used.
I based this replica on the latest 370Z GT4, built by RJN Motorsport with extensive parts from NISMO bin The engine is unique ( HR version fly by wire throttle ), natural aspiration + tuned exhaust and NISMO expertise + parts, stroked to 3.8 litres, produces close to 440HP. For BOP ( balance of performance ), the engine is tuned to produce 410PS instead or 404HP.
The body has been lightened and seam welded with weld in cage, the car tips the scale at 1300kg.
Suspension comes from custom coilover with Swift springs and 2 way Bilstein damper. I set the springs at both 16kg/mm to maintain solid composure during hard cornering. The balance is very well maintained from entry to exit. Camber has been set quite aggressively to provide much needed traction on medium to high speed corners. Damper and ARB are tuned for less roll, but still gives some room for the tire to flex and grip with traction by minimizing excess weight transfer under acceleration.
The car uses QUAIFE 6 speed sequential gearbox, with specific ratio setup for 370Z, while still using stock final. This gives the 370Z good spread with plenty of pull and respectable top speed at just over 260km/h. Lower the final if wanted more top speed. The real car has twin plate Alcon Clutch, and twin plate clutch is installed in this build.
LSD comes from NISMO GT Plate LSD, I setup a 2 way with high preload to maximize traction. Brakes IRL comes from Alcon with 6 pot front and 4 pot rear and large diameter discs.
The rear wing is custom, there are variances in real life, some uses low profile rear wing that looks close to NISMO wing, some uses bigger carbon fiber GT style wing. I used custom wing in this replica.
To replicate the lap time done during European GT4 Cup, I used Sports Soft tire. The real life 370Z GT4 laps Silverstone GP at 2:15.069 back in 2011 GT European Cup in the hands of Jordan Tresson / Alex Buncombe, GTA winner. On SS tires, the replica easily can break into 2:14s, similar to the quickest GT4 cars in real life ( M3 GT4 )
I also tested the car at Brands Hatch GP and Bathurst back in 1.08. Thanks to the help of @danbojte with further testing the car on 1.09 and wheel, the tune proved to be solid and posted as is. The replica should also work on Racing Hard tire.
ENJOY
