Plain and simple, If the car is under your parents name have them go and take care of it. They wont suspect foul play. If not, PLAY STUPID. Be like: " I dont know what happened, my car just started acting funny. What the hell..ive been having so many problems with this car and i barely even drove it since i got it." something like that i guess. Seriously though, why race??..ahh it drives me nuts at the idea of people street racing. Its so dumb. But eh ive made a few mistakes too. I guess we all learn sooner or later. Lemme guess. You have a gt, you were losing so you figure the more you downsfhift the bigger the boost? I did that when i first started driving. Ant way, I wish you the best of luck.
