Hello all...I'm just looking for info on what spring rates I should start with on my rocco racer that I'm working on.I hate the 2 pc. springs that came with the raceland coilovers,and want to replace those with a 1 pc. spring.I measured the free length on the springs and it's 11" long,and the I.D. is 2 3/8".I think 500 lbs on the RF spring is good IMHO,but what about the others? What have you guys been using for spring rates on the Mk1 type cars? The track is a 3/8 mile paved oval with little banking.Thanks for your help!
