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.
