The setup works fine, but it is overpowered with 709 hp. To make it handle like a race car I suggest a wing for downforce, better braking and more stability. LSD acceleration down around 10, drop the supercharger and run it with 340-480 horsepower. Improve body rigidity, like the rollcage and anti-roll bars do to real race cars. Then it will be a Trans-Am replica. I tried it, and it works. They ran with 340 hp in the late sixties, and the 1970 5L V8 engine had max output a bit over 450 hp. Thanks for the setup, and keep up the good work!
