Nothing can go on the carbon fiber. Carbon Fiber is carbon fiber, you can't do anything to change the look.
Steel...I usually hitt he NOS when I get into third gear. It makes me mad when I can hitt he perfect shift every time. I think I got my GTO to do it in 8.1 last night but I can't get any better than that.
Taz. Drift races are fun, I especially like the downhill ones. The trick is to have lots of speed when you do it. If you have a lot of speed, turn a little early and tap the e-brake a few times, It'll whip around the turn real fast. Sometimes I can get 25 to 30 thousand points on one drift. You only need to do a couple when you get points that high. And there is no time limit on there, so take your time.
BT, I race with the arrow keys most of the time. I only use the joystick for drags because its much easier to shift then.
