RideTech StreetGrip debuts at SEMA!

Composite leafs don't eliminate spring wrap.

The problem I had with composite leafs is any leaf needs to be near-flat (and pass through flat in their travels) at the rear of a Camaro for a nice lowered ride height. First gen at least. The composite technology is laid-up expecting certain surfaces be in tension or compression - they didn't like reversing those forces as they passed through flat. Not a problem if the car is going to be kept high or spacer blocks (with their attendant ills) are ok.

I've got 3-4 sets of composites against the wall at home from Hyperco, Flex-A-Form, and others...went back to steel

We have found that "spring wrap" is typically a function of shock's rebound control. Our first attempt with the composite leaf was with too high of spring rate, coupled with a shock that did not have enough rebound force available. the result was not only a poor ride quality, but spring wrap as well. We then lowered the spring rate [to gain ride quality] and adjusted the rebound range...that resulted in a great ride quality, much improved handling performance, and no spring wrap. We had this same experience with steel spring as well so the spring wrap issue would seem to follow spring rate and the lack of rebound control, no matter the material of the spring.
