Max Torque : 35.7kgf-m / 4700rpm

Exhaust Muffler : GReddy Comfort Sports GTS Ver2
Engine Control Unit : EcuTek

Clutch : JUN Single Sport Clutch Kit
Coilover Damper : ENDLESS ZEAL FUNCTION X HARD ( X Coils )
Tire : ADVAN NEOVA AD08R 255/35R18
Wheel : ADVAN Racing RS2 18inch
I built the replicas based on JUN infos and another car data used for track with mild weight reduction.
Suspension use Endless Zeal Function X Hard Spec with X Coil Springs. Spring rate set at 10k/9k.
Using my experience with Tein SRC BRZ and Amuse GT86 builds, I set the damper with neutral balance in mind. While alignment and ride height uses another test car specs which should give the car distinct feel and handing. I have also provided low camber setup as well as variety damper sets recommended for certain tires. The optional higher ride height is set at 122/124, should be used when needed at bumpy tracks.
Weight set at modest 1176kg, a healthy 50+kg diet easily achievable IRL for track session purposes. The weight distribution has been set using real life corner weight of the car with 1176kg weight. At 56.9 /43.1 distribution, reflected in ballast position.
For power and torque, to reach the same spec, I used extensive power upgrades in GT6, and oil change to achieve very close torque number 35.7kgf-m or 258ft lb.
As the real car only has mild modification, the LSD, transmission, and drivetrain parts are stock. The tire used IRL is Advan Neova AD08R ( soft compound ) with bigger size and contact patch at 255/35/R18, this is similar to Sports Medium in GT6. The replica can still be driven with comfort soft with ease, managing 1:05s at Tsukuba.
I tuned and tested the car both online and offline, Tsukuba, Willow Springs and Red Bull Ring ( both ). With SM tire at Red Bull Ring Short, it can easily lap in 57s range, a very quick time for 470PP car and only suspension tweak.
