That is a weight-jacker. The driver could change the spring rate by adjusting with that handle.

oh he didn't I'm sorry about the comment of Jesse dying in a car I was just saying of what i've seen on different forums and what I was told. I will look up more to that and remove the comment of Jesse once again sorry for saying Jesse died in car.

Cage looks like it would crumple like a tin can in the lightest of rollovers or impact.

Got to love the jacket!

If you look at the older cars. The drivers arms are out side the roll cage. Why the modern car has a wider roll cage, opening on the top is bigger. Back then you saw a lot of car-tire into the side opening of the cars. Only way to cover all the different openings would be to turn it into a stock car. Remember in the 80's cars had the lower bar from back of the cage to the front. I always liked Andy Granatelli's STP suit
