Re: coilovers for C10

There are a few factors that go into the selection. First is the "real" spring rate or the rate at the wheel. That will change significantly. The angle of the shock will play a role as well. There are different length springs, the longer the spring the required rate also goes down.
I have built my own mounts and have the lower shock mount as close to the ball joint as I could get it and am using a 12 inch spring. I am running 500 lb/inch springs. I had tried some 650 and these seem much better. There are several calculators out there to help.
