You get a different car. Crossfires are track cars, not drag cars. It takes 6.5 seconds to get to frikkin 60. How else do you think we can top out at 186mph (with retarded limiter removed) with only 215 horsepower or watch a Viper not be able to hit a good turn even close to as good as you going 135-140 on the freeway and watch him slide, brake and fall back in your mirror (my shining moment), how do we do that, huh? Because we sacrifice acceleration. If you wanna be bored goin in a straight line and gettin a 15 second thriil, get an American or Japaneese car and mod the hell out of it so you can only get 11 seconds on thrill. Crossfires are way too well engineered to be insulted by going in the same straight line again and again. You own a magnificent machine, use her for what she was made for and learn to track race and I promise you won't be asking "how can I improve?", you will be asking "where can i find a more challenging track?"
