Have a straight axles lbz and want to get new shocks. I want it to ride like a 57' caddy. Just glide lol. Can anyone tell me what spring rate would be good, rebound?. And also should I put and emulsion shock beside the coil over? The size are 10" travel thanks guys. Oh an pointers on how to get the rear better too please have 1 ton springs in the rear now.
