Roy, my computer has gone berkshire, and refuses to let me access PDF files, but if it's what I think it is, that is the most overlooked, and missunderstood item on a race car, and people will argue about it more then being caught with a big, or borderline motor. The problem I find most folks don't understand, is the big one, what the belts are designed to do, the lap belt holds you in, the crotch strap keeps you from sliding under the lap belt, and the shoulder belts keep you from going forward, not pull you down in the car, most of them think they have to pull your shoulders down, and that's totally wrong, that only makes a hard crash worse, especially if you land on the wheels, and I understand a lot of cars have different drivers, but they need to work out something, to keep the short guy, and the tall guy, safetly under the shoulder straps, not crunched down in the seat. Bob!
