I have made this setup for the subaru brz as a racing tune.
I have maxed it out and with racing soft Tyres, it's at 559pp.
Suspension is:
Height
83. 83
Spring rate
5.90. 7.90
Compression
5. 5
Extension
6. 6
Roll bars
2. 2
Camber
0.6 1.2
Toe
-0.10 0.10
Brakes
5. 5
Lsd
Initial
15
Acceleration
35
Braking
30
The car has good weight balance and grip.
I don't know about tuning the transmission, I need to understand it more but the downforce is full 20, oil change and Rigitity improvement.
If you can improve on this one it would be great just post it back.
