Remember guys there's a BIG difference between going to the track once or twice a year or twice a week. Even track to track or how well the cars hooks makes a big difference. I know I broke my share of them years ago and my son's broke this year but heck I also cleaned the teeth off my race prepped 9 inch in my light-weight Daytona and its a slow 1.20 sixty foot. Everything has a life span on a race car.
