Solid suspension

NHRA has just announced that in the 2001 rulebook all Sportsman, Pro and Superpro cars will a wheelbase of 100 inches or longer may now use rigid suspension to make the rule book more consistant with Super Gas/Super Comp cars.

Since the third gen's are 101 inches I would qualify. What kind of changes would I need to convert my rear suspension to solid and be strong enough for drag racing? I would assume the shocks and springs would go and some sort of solid rod would replace them. Perhaps an adjustable length rod in the shock positions so rear height could be adjusted.

Steve Spohn: Could you come up with something that would work?
