Put a nice little percantage on it and sell each one...

I agree they are a great safty item, but when the current rules everywhere else does NOT REQUIRE them, seems kinda crazy that we need one for this race. With only 4 working days to go, and being this late in the season I guess the guys that dont have em will have to stay home. Guess I'll be spectating and watching the Shakedown struggle to get a 16 car field in X275.

X2..... I think this will keep alot of us out. With only 3 to 4 days to get this done. They dont always fit the first time around.Turbo car usually need some fireproofing on them. Our headers tend to get alittle hot....

Anyway we can get a one race wavier on this????
