I understand that FIA has rules for their car classes. Where I'm coming from is an issue of driveability for me, personally. I can't spend the money on a wheel and pedal setup, so I'm stuck with a controller. I never got comfortable using the L2/R2 for gas and brake. Therefore, I use X and square buttons, which means full throttle and full brakes. Full throttle with an AWD car is fine. With RWD, I have to have the TCS at 2, which, of course slows me down. I don't mean to subvert the class rules, just hoping to be competitive in GR3. I assume there's a lot of other people in the same boat.
