Monte.. lets do this a different way.. a 3" belt has more stretch over a 2" belt... do you agree.. in a race car you are wearing 4.. 3" belts and a 2" dive strap.. do you agree.. in a street car you wear a lap belt of 2" and a single 2" shoulder belt... this simple system keeps a person in the car on impact... as does the 3" system... the cage is what keeps the big hurt off of us.. both in a street car or the race car... the belt keeps you in the seat.. and if the seat mounting is wimpy you STILL get hurt.. but yet no one puts the big value on this(NHRA OR SFI)
