It is impossible to race with the traction control on. When you launch it basically kills the motor. The harder you launch the harder it kills the motor. Mine has been permenantly turned off for two years.
I didn't find it useful in the snow either. Having driven rear wheel drive cars my entire life I could actually react faster than the traction control. Besides, there nothing wrong with turning the corner in the snow with your back wheels. Actually, its kind of fun.
