I have always felt if you are afraid to break something, then no sense in taking it to the track. Either go all the way or don't go at all. Of course if its your daily driver, and you count on it to get you to and from work/school everyday, then I wouldn't, but if you have another car, its definately time to bolt on the slicks and have at it. If not, I'll take them off your hands cause I need a set!!
