This Corvette replica was so much fun to drive at Willow Springs, I'll run some laps again and beat the 1:31.4 time on the "snow" tires It squeals a lot
The driver in the video is quite quick, but not as quick as pro/racing driver who set even quicker lap time on stock Z06 equipped with Eagle F1 factory fitted tire
The real life race car driver of the C5-R Vette pulled the magical lap on stock Z06 C5 with OEM Eagle F1 tire to prove his point to a motorcycle magazine that pitted the Z06 C5 against Suzuki GXR1000 - both were tested by Kevin Schwantz - a main feature article of the mag. The test run were heavily biased in favor of the bike and the Z06 C5 was driven with TC Competitive Mode enabled. The magical lap was close to 4 second quicker than the Schwantz manage to pull off. I managed to replicate the magic lap with the replica I think I had some slow section ( 2 corners were hairy ) that could shaved another tenths or two at the very least.
Very nice, Orido. đź‘ŤThe real life race car driver of the C5-R Vette pulled the magical lap on stock Z06 C5 with OEM Eagle F1 tire to prove his point to a motorcycle magazine that pitted the Z06 C5 against Suzuki GXR1000 - both were tested by Kevin Schwantz - a main feature article of the mag.

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

OK. Well, I would like to see more replica tunes from you, your tuning garage is awsome! đź‘ŤSports Soft already give too much grip, IRL most GT4 cars qualifying laps at Silverstone GP are around 2:14s, some are high 2:13s. SS tires can reach/beat those lap times with GT4 replicas on same power/weight/gearing specs. I will make correction on the M3 replica, should be E92

Alright. Do them when you can. Good luck. đź‘ŤI'm not taking further request now, I can't even find more time to post the already completed cars ( 30+ waiting in my garage ). There are some rally cars that are already completed, I'll try to squeeze one in on the next batch

It is my experience that SS tyres have more grip, if not more endurance, than RH tyres.

Notes :
This is one of my hardest to make replica, I had to researched everywhere, magazines, forums, and technical docs. The real CS V3 has 200PS base engine in tech specs, but for racing use, it has FIA approved racing exhaust + catalyst and TMG Updated ECU. I decided to use whatever power in GT6 has with racing exhaust + ECU + Catalytic converter. The tire is Pirelli DH slick, but in GT6, racing hard has too much grip, more like DM/DS slick, so I opted for sports medium ( similar to R comp semi slick ) or sports soft ( similar to DH slick IMO ) with optional to use racing hard.
Suspension of the real car is Ohlins TTX36 2 way Racing coilover with main + helper springs. To adapt these springs, I combined both to one spring rate The real car uses 2 rear differential option, one stock open diff with 3.727 and torsen LSD with 4.100 ( GT6 stock LSD + gearbox came with this ), I have included both, use the 3.727 transmission setup with open diff LSD setup.
Everything else are as close as possible to real car. Enjoy the drive This car will be great for spec endurance racing.
The car in action IRL :
UPDATE : Major update to the suspension, ARB has been tweaked, camber and toe alignment has been corrected, added optional spring rate setup ( there are differing opinion on helper springs being calculated into main spring rate - both are listed, one do not and another include helper spring rate in total value ), added both rear diff offered by TMG, FD20A ( open diff with 3.727 gear ) and FD20AT ( Torsen diff with 4.100 gear - came with stock GT86 in GT6 )

Notes :
The real car is not yet released, but I already made a would be replica Okay, the TMG 86GT CS R3 rally car is for 2015 season. Based on CS V3 Cup success, TMG plan to enter the rally world with FR 86GT. With different R3 rules than VLN V3, the car has less weight, more power and upgraded with mechanical LSD, rally spec suspension, and sequential gearbox.
The replica is WIP, meaning when the car actually released with additional infos, I will update the tune to reflect the new spec. In the mean time, this will do, built for tarmac, dirt and snow, the tune works for all surfaces, 3 sets of tires ( SM, Dirt and Snow ). The R3 replica tested and tuned at Toscana, Chamonix, Matterhorn, and Eiger Trail.
Have fun sliding with 86 GT, the FR heaven

Notes:
This Lamborghini Gallardo replica is based on Reiter Engineering Gallardo GT3-R that has been sold from 2006. Specs based on 2010 model year GT3-R with 520HP, 1190kg and 40/60 weight distribution.
The weight distribution can't be replicated without getting the car overweight, so I decided to stick with stock weight distribution 44/56. Weight at 1190kg and power set at 520HP.
Suspension is quite tricky on this car, I setup the front spring rate to be as responsive as possible to avoid understeer. The rear spring rate is optimized for balance, any higher or lower will alter the car handling behavior, so it's very much well tweaked so you can fine tune the car just by lowering or raising rear spring rate. More higher rear spring will cause oversteer, while lower will make the car harder to rotate.
Damper has bee tweaked to support the stiff springs, giving good traction out of corner and able to brake very late without losing grip at the front. ARB set at same stiffness as it gives the best balance. This will give the Gallardo go kart like handling, direct, responsive and raw.
LSD is 2 way, based on real life spec of 45% lock LSD, the front has been set at all 5 to give as close as possible to open diff. Torque has been set at 90% rear, sadly 100% is not possible to make RWD Gallardo GT3-R. Fear not, the car has been tuned to feel and drive like a RWD as much as possible.
Gearing comes from homologated Gallardo GT3-R 6 speed sequential ratio with custom final to give balance of top speed and acceleration.
I tuned and tested the Gallardo GT3-R at Tsukuba, Brands Hatch GP, Silverstone GP, Bathurst and Ascari.
The car is capable of low 54s at Tsukuba and 2:02s at Silverstone GP during early build phase.
Please leave feedback about the replica, I always consider this car as a work in progress

"To the Editor:
I’m writing this on behalf of the Corvette owners and other sports car enthusiasts who encouraged me along this path. A few months ago I read an article in Motorcyclist magazine. The cover story was a track evaluation of a Corvette Z06 and a Suzuki GSX-R1000 with ex-500cc World Champion motorcycle racer Kevin Schwantz as the dedicated tester of both vehicles. I thought it was a very interesting concept for an article. After I read it, however, I had one major issue: I felt that the lap times for the Corvette were not where they should be and showed the Corvette in a really bad light. This opinion was based on my own experience with the Corvette Z06 and my testing of numerous cars at Willow Springs (the test track), even though the last time I was there was at least four years ago.
I received several e-mails from people who had read the article and wanted to know what I thought about it. Without exception, after I gave them my opinion, they suggested I go to Willow Springs with a Corvette Z06 and run it, to prove something one way or another. One of the guys I discussed the article with was Joe Policastro, owner of Grabiak Chevrolet in New Alexandria, PA. Joe not only suggested going to Willow Springs, but also put up the money and rent Willow Springs for a few hours just to set the record straight. Grabiak Chevrolet sells a lot of Corvettes and Joe definitely took it personally after having to defend the Corvette to some of his customers after they questioned him about the article.
The biggest issue I had with the article was the difference in best Willow Springs lap times between the Corvette and the Suzuki. Kevin managed a best lap in the Corvette of 1m 34.2sec and a best on the Suzuki of a 1m 26.6sec, a huge gap of 7.6 seconds. The major point of the article seemed to be illustrating how areas the bike was better than the car virtually everywhere around the circuit. They even used “Smackdown!” as the article title. But as a current professional car racer, ex-motorcycle racer and current street motorcycle rider, I felt this was unfair to the Corvette and to sports cars in general.
For our Willow test we managed to get the use of a totally stock Z06 with 1,500 miles on it. Ex-Toyota race ace Dennis Aase is a buddy of Joe’s and provided us with some of his crew to change tires in the August desert heat – much appreciated. For the first test runs I used the Z06’s standard Goodyear F1 tire. My best time was 1m 30.6sec lap on my fourth hot lap. I then fitted Goodyear’s DOT-approved “S” compound version of the F1 and we ran 1m 28.3sec lap on the third hot lap, just 1.7sec slower than the Suzuki and 5.9sec quicker than Motorcyclist’s time for the Corvette.
Incidentally, we used the “S” compound Goodyear F1 to compliment the Motorcyclist test, as the magazine had used an “S” compound Michelin on the Suzuki for their fastest laps. Motorcyclist also used Pi Research data to overlay the bike time with the car time and according to the times the car looked slow everywhere. With my lap time for the Corvette reasonably close to the Suzuki, and the acknowledging the superiority of the bike on the straights, I think the car would probably actually show quicker than the bike through most of the corners.
In the end we achieved our objective, which was to satisfy ourselves that the Corvette is a much more competitive machine than the article showed – even when compared to the top sports motorcycle in the world.
Finally, I would like to add that I have nothing but respect for Kevin Schwantz. The guy is still, I’m sure, a bullet-fast motorcycle rider and an accomplished car racer. I think he was handicapped in the Corvette for a couple of reasons. Firstly, he used the traction control. Even in Competition mode it can slow you down when getting really serious. Secondly, Motorcyclist put a different manufacturer’s tire on the car; they were not the OE tire and may not have been a good match for the Corvette.
In case you’re interested we have photos and data to confirm what we did at Willow Springs. The Corvette Z06 is an amazing car and deserves a better representation than Motorcyclist gave it. I think the record just needed to be straightened, for Corvette and for the many sports-car enthusiasts who shared with me their strong feelings about the article.

Randy: "There's kind of not a bad corner for this car. I've never felt a car grip up so much halfway through Turn 9. Turn 9 is downhill and when it levels out I could corner harder. Cars are kind of floaty here. This one, not so bad, but it feels like with the speed it's carrying it's not going to grip up. And it did. It would land and grip up and I could roar, just go for it."

Notes :
The C5 Corvette was one those cars that never gets old to look at I love the shape from the side, the curve of the hood, the short tailed rear end, the C5 just shows what a sexy woman can be in the form of a car
This replica is a stock car complete with stock tires replicated.
The power of the C5 Z06 was originally 385 HP when it was 1st released in 2001. Then the car went some changes from 2002 model year, the LS6 engine was upgraded and it grows in power to 405HP with 400lb ft torque, a good increase that also paired with lower weight than the base C5. The test curb weight of the car during Car & Driver Test was 1418kg, this will be optional. I used the heaviest running order weight at 1474kg, about 3250lbs. Weight distribution is at 53.5 / 46.5 as tested by C&D, this is reflected in ballast position.
Suspension for C5 Z06 comes in FE4 Package, different than the FE3 Sports Suspension which was available for Z51 C5. The front transverse composite leaf spring is 525 lb/in in rate, similar to FE3 Z51. The rear transverse composite leaf spring is 714 lb/in, stiffer than the FE3 Z51 rate at 634 lb/in. The Damper and ARB has been setup to give neutral balance, with FE4 Sway Bars Package taken into consideration ( 31mm / 23.6mm ). My personal alignment is used, using the factory range as a base. I provided additional alignment setup, feel free to try them.
The C5 Z06 comes with limited slip differential ( GU6 ), I have used some preload and medium lock to simulate the LSD, this gives much needed traction and stability around Willow Springs ( Big Willow ).
The rear wing is optional, feel free to install it. I simply like the look of it.
The C5 Z06 was tested and tuned at Tsukuba, Silverstone GP, Willow Springs ( Big Willow and Streets ), Red Bull Ring and Laguna Seca. The main aim in this replica is to replicate the lap time at Big Willow that was done on stock factory tire - Goodyear Eagle F1 Supercar. This is comfort medium in GT6 The lap time was 1:30.6s on 4th lap by the legendary Corvette Race Driver, Andy Pilgrim. He also fitted Goodyear’s DOT-approved “S” compound version of the F1 and posted 1:28.3s on 3rd hotlap ( feel free to try replicate the time using comfort soft )
The real life race car driver of the C5-R Vette ( Andy Pilgrim ) pulled the magical lap on stock Z06 C5 on 4th lap with OEM Eagle F1 tire to prove his point to a motorcycle magazine that pitted the Z06 C5 against Suzuki GXR1000 - both were tested by Kevin Schwantz - a main feature article of the mag. The test run were heavily biased in favor of the bike and the Z06 C5 was driven with TC Competitive Mode enabled. The magical lap was close to 4 second quicker than the Schwantz manage to pull off. I managed to replicate the magic lap with the replica I think I had some slow section ( 2 corners were hairy ) that could shaved another tenths or two at the very least.
Here is a quote from the letter sent by Andy Pilgrim to the Editor of the Magazine in 2003 :
"To the Editor:
I’m writing this on behalf of the Corvette owners and other sports car enthusiasts who encouraged me along this path. A few months ago I read an article in Motorcyclist magazine. The cover story was a track evaluation of a Corvette Z06 and a Suzuki GSX-R1000 with ex-500cc World Champion motorcycle racer Kevin Schwantz as the dedicated tester of both vehicles. I thought it was a very interesting concept for an article. After I read it, however, I had one major issue: I felt that the lap times for the Corvette were not where they should be and showed the Corvette in a really bad light. This opinion was based on my own experience with the Corvette Z06 and my testing of numerous cars at Willow Springs (the test track), even though the last time I was there was at least four years ago.
I received several e-mails from people who had read the article and wanted to know what I thought about it. Without exception, after I gave them my opinion, they suggested I go to Willow Springs with a Corvette Z06 and run it, to prove something one way or another. One of the guys I discussed the article with was Joe Policastro, owner of Grabiak Chevrolet in New Alexandria, PA. Joe not only suggested going to Willow Springs, but also put up the money and rent Willow Springs for a few hours just to set the record straight. Grabiak Chevrolet sells a lot of Corvettes and Joe definitely took it personally after having to defend the Corvette to some of his customers after they questioned him about the article.
The biggest issue I had with the article was the difference in best Willow Springs lap times between the Corvette and the Suzuki. Kevin managed a best lap in the Corvette of 1m 34.2sec and a best on the Suzuki of a 1m 26.6sec, a huge gap of 7.6 seconds. The major point of the article seemed to be illustrating how areas the bike was better than the car virtually everywhere around the circuit. They even used “Smackdown!” as the article title. But as a current professional car racer, ex-motorcycle racer and current street motorcycle rider, I felt this was unfair to the Corvette and to sports cars in general.
For our Willow test we managed to get the use of a totally stock Z06 with 1,500 miles on it. Ex-Toyota race ace Dennis Aase is a buddy of Joe’s and provided us with some of his crew to change tires in the August desert heat – much appreciated. For the first test runs I used the Z06’s standard Goodyear F1 tire. My best time was 1m 30.6sec lap on my fourth hot lap. I then fitted Goodyear’s DOT-approved “S” compound version of the F1 and we ran 1m 28.3sec lap on the third hot lap, just 1.7sec slower than the Suzuki and 5.9sec quicker than Motorcyclist’s time for the Corvette.
Incidentally, we used the “S” compound Goodyear F1 to compliment the Motorcyclist test, as the magazine had used an “S” compound Michelin on the Suzuki for their fastest laps. Motorcyclist also used Pi Research data to overlay the bike time with the car time and according to the times the car looked slow everywhere. With my lap time for the Corvette reasonably close to the Suzuki, and the acknowledging the superiority of the bike on the straights, I think the car would probably actually show quicker than the bike through most of the corners.
In the end we achieved our objective, which was to satisfy ourselves that the Corvette is a much more competitive machine than the article showed – even when compared to the top sports motorcycle in the world.
Finally, I would like to add that I have nothing but respect for Kevin Schwantz. The guy is still, I’m sure, a bullet-fast motorcycle rider and an accomplished car racer. I think he was handicapped in the Corvette for a couple of reasons. Firstly, he used the traction control. Even in Competition mode it can slow you down when getting really serious. Secondly, Motorcyclist put a different manufacturer’s tire on the car; they were not the OE tire and may not have been a good match for the Corvette.
In case you’re interested we have photos and data to confirm what we did at Willow Springs. The Corvette Z06 is an amazing car and deserves a better representation than Motorcyclist gave it. I think the record just needed to be straightened, for Corvette and for the many sports-car enthusiasts who shared with me their strong feelings about the article.

Notes :
This replica is very hard to built with very limited information available on the car. Early 2013, the car was on the news, it may have been the first 86 built for GT4 class.
The GPRM Ltd who built the car stated it has 350-400HP with turbo added. Not much else was disclosed, so I have to improvise. I used the base model for CS V3 Cup car as a base setup for the GT4 car. Suspension uses similar spring rate with revised ride height and tweaking on the damper, ARB, toe and camber. The real car uses Eibach Sportsline coil springs and Koni 2 way fully adjustable damper.
LSD uses high preload 1.5 way with medium/high lock 55/75 to replicate Salisbury type diff used on the GPRM GT86 GT4. I leave the gearbox in stock form as it's more than enough to do the job and quite versatile on various tracks ( the real car has 6 speed sequential conversion but may still uses stock ratio as the Brit24 86 car also built GPRM uses stock ratio ). Weight distribution has also been fixed ( similar to the CS V3 Cup car ) The weight figure is slightly less than CS V3 Cup 86, with 1190kg, I pick this value considering the GT4 car has stripped out interior, perspex windows, lightened body shell and similar chassis modification to CS V3 Cup.
For closer performance compared to other GT4 cars, I decided on 399HP power using mid rpm turbo, this allows the GT86 to lap quite close to real life times at Silverstone GP. During testing, the car is capable of 2:13s lap on SS tire.
I tried to test this replica alongside some other GT4's but there is NO transmission
BTW M3 GT4 at the moment is OP with 420 hp but with SRO BoP is underP
