Not familiar with jolly joints, but I'll ck that out. I was thinking heim joints in chrome moly, but would make it pick up everything in the road. If this set up is that bad, why would so many people use it along with Nascar? If you would use coil springs and regular shocks you wouldn't have a whole lot invested. Checker racing has a 4 bar set up with coil overs, panhard bar, crossmembers, complete for $575. I got a lot of the steel, I just thought aa person could build a good set up, save some money, and have the satisfaction of doing it.
