You're right about the specs of the G4. On this link you can find some real specs and the redline is indeed at 6500.
I had the torque a bit less than the real car because the tires didn't hold otherwise. If you're tire specs are better then that's great.
The brakes of the cars is indeed something I didn't pay allot of attention to in the past so the brake specs have to be reviewed.
If you give me the real torque with the 6500 RPM, I can try to make tires good enough to be able to to 0-60mph is around 3.3 seconds , 0-100 mph in 8.2 s
I hope the G4 will me much faster on the ring(to try to do 7:42 a lapâ¦)
