C10 coilover spring rate for autocross

[SkinnyG]

My previous daily was a squarebody C10, and I ran 1060lb 1-ton coilds up front and "Big 10" (8?) leaf pack out back. It was firm, but ride quality is subjective.



I recommend learning how to calculate spring rates based on suspension frequency, and chose your springs that way. It's a bit of measuring and a bit of math, but I do all my autocross cars this way and have had very good success doing so.

I'm sure there are online sources, or if you prefer books I can send you links to some. I prefer books - people who don't know what they're talking about are less likely to write a book on the subject.
