Notes :
It all started with a message from a fellow member DanbojteThen 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 bornIt'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 brakingSo, 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
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
ENJOY

Notes :
The McLaren is one of the most fun replica I ever built
This base GT3 replica has only 500PS and 1240kg, but it's performance is on par with proper GT3 racing cars on similar power.
I provided 3 different sets of camber this time, feel free to try all of them, and pick the one that gives the best feel on the track. Everything from spring rate, damper and ARB has been tuned to work with all 3 camber sets, toe also tailored to suit on each camber setup.
LSD is 1.5 way this time to make the car easier to push with camber setup.
For gearing, I have no good information on the ratio, some sites mention Ricardo 6 speed, others mention Xtrac 6 Speed, so I decided to use 416 Xtrac ratio, and it worked quite well on the car, giving ample top speed and acceleration. The gear can be used for engine braking effectively for stabilizing the car under heavy braking or just to help the nose pointed on apex in medium and low speed corners. Never fear to shift down on 1st and 2nd to help the car change direction.
I tuned/tested at Silverstone GP, Bathurst and Nordschleife this time. Even with High Camber setup, the MP4-12C GT3 is capable of 2:02s lap at Silverstone GP on RH tire.
The camber setup has been tested on RH tire only, take your own risk using it on SS tire

Notes :
The MATECH Ford GT GT3 was famous back in 2007 and 2008.
This replica is based on the car. First of all, I can't get the weight of the real car at 1180kg, so I decided to use 1200kg and maintain the stock weight distribution at 47/53.
Power is at 550HP, this time I also provided the low power version, suitable for Blancpain spec of sort at 500HP.
Suspension of the real car was based on Eibach springs and 2 way Bilstein racing damper. I used high spring rate at 15kg/mm front and 20.20kg/mm rear. This gives very good stability at smooth tracks, with damper set on softer side to maintain composure on bumpy tracks and keep the rear stable. The balance is easily shifted with trail braking and sharp steering, giving good turn in and stable directional changes.
I have provided 3 sets of camber setup, each with tailored toe values. Try them all, use which one you prefer.
LSD is 2 way, with medium preload and high accel + braking. For gearing, the real car has Hewland 6 speed sequential, I used the same ratio fitted on the Ferrari 458 Italia GT3, and it works so well, and gives the ability to use the lower gears to maintain speed and stability through low and medium speed corners. Very useful on esses like at Suzuka. The car also uses Tilton Triple Plate clutch, so I installed triple plate clutch on this build.
The MATECH Ford GT GT3 was tuned and tested at Silverstone GP, Bathurst, Suzuka and Brands Hatch GP.
During testing, with 500HP low power and camber setup, it was capable of 2:02s at Silverstone GP and 1:59s at Suzuka on RH tire

Notes :
The Camaro GT3 had a rough start back in 2012, the first European team from Germany who used the car, YACO Racing Team struggled to be competitive, spending most of their racing time at the back of the pack, several seconds off pace in lap time.
But, that's not the reason for not making this replica
This build is trying to replicate the full power spec of the Camaro GT3 built by SaReNi United / Reiter Engineering. The car has 650PS and over 800Nm of torque, with 1310kg of weight. I can't replicate the car weight distribution at 55/45, so I used the closest I can get.
I installed flat floor on this build, a different approach to replica, this time I tried to get closer cornering speed of GT3 race car, and sacrificed top speed as well as acceleration. But, I do gain better traction, better stability, easier to push on the limit and ultimately more realistic top speed, able to replicate real life top speed of 279kmh at Monza with chicane - similar to real life 2014 test laps. There are subtle differences in balance compared to non flat floor, so it might takes time to get used to. The flat floor also added PP to 613, quite an increase from 582
Suspension has been tuned with added aero downforce from flat floor in mind, damper, ARB and spring rate are optimized for balance of traction and stability on racing hard tire. I decided to use higher rear spring rate to make the car more willing to rotate while very controllable. There might be slight push/understeer, but it's more for safety cushion, so you know you are reaching over the limit and the real car also has unique understeer traits.
LSD is 2 way as usual for this type of car ( racing tire ), I tuned the preload pretty high to avoid sudden changes in grip between rear tires. While high locking rate make sure traction are even near the limit.
For gearing, I used previous replica GT3 homologated gearing and adapted for this car, as I couldn't find detailed info on Camaro GT3 homologation gearing. Final has been setup for good launch on 1st gear, while having good top speed and acceleration throughout the gears. I also aimed at replicating real life top speed.
I tuned and tested at Tsukuba, Brands Hatch GP, Monza with chicane, Bathurst, Silverstone GP, Nurburgring GP/F, Nurburgring GP/D, and Fuji Speedway F.
It was capable of easy 2:03s at Bathurst
For reference : The BOSS YACO Racing Camaro GT3 managed to a best lap of 2:00.564 at Nurburgring GP/F in 2012, and 1:29.039 at Nurburgring GP/D, also on 2012 ADAC GT. Feel free to aim for these lap times
ENJOY
