I just bought a 1" 4 hole composite plastic super sucker and it says for race use only. Why do you think this is? Do you think it would be ok on a car that gets driven about 600 -1000 miles in the good wheather ? This is a car that will get driven to local shows and such and raced as much as possible. Anyone run one of these and how do you like it if so? Any help would be appreciated.
