I ran a 12.9 with traction control on.. lol.. Though, if you happen to chirp 2nd or 3rd, the car will fall on it's face.. And if you break them loose at the upper end of 1st or 2nd gear it will also wreak you havok.

Anyway, traction control just killed my back rotors and pads.. lol.. It is permanently off now.

Also, the car will not seem fast until you get into the boost. There is probably a 250hp difference between 3/4 throttle and full throttle.
