I would say for you to read your warranty booklet that came with the car.
I bet there is a line in there about "driving in a timed event" or abuse, racing etc....
With that being said, If you break something and it is because you were drag racing, I doubt it will be covered. But if after you drag race, the cd changer stops working, I would think it would be covered....cause and effect...
Cheers,
