If regular brakes are adjusted properly they should not lock up under heavy decelleration. That will give true stopping distance. I don't know about you other guys but I'm not going to go so fast that I can't control my H and I'm not about to follow another vehicle so close that I have to slam on the brakes to keep from hitting them. I just make sure I have enough distance between me and the other car so that I don't have to have a fender or hood made. Mike Meyer [Non-text portions of this message have been removed]
