Last year I installed an xtra 10 skid into a indy 400. I bought new aftermarket shocks and installed them. I didn't replace the springs though. When I hit the gas or stand/sit further back on the seat the suspension compresses real easy, too easy. How can I fix this and stiffen it up a bit. Would moving the back pivot arm stop blocks to the forward position help. Would new springs also help. What would happen if i tighten up the spring tension on the front skid shock. Any help would be appreciated.
