Our HQ van has has leaf springs suspension and a ten bolt diff. Our intentions are to make it a show car, but we also want to ultimately enter the burn out comps, such as the summer nats... Should we leave the leaf springs in, or is there a kit or something to change to coil springs? Or, is there a way to add something to the leaf springs to stop them tramping, as I am not too keen on putting on tramp rods. I am getting ready to get the chassis powder coated, and am wondering if I need to make any modifications to the chassis before it gets coated. Any suggestions?
