I thinks that's a chart of primary springs, but thanks for the help.

I'm interested in the EPI white spring because I like that they post their spring rates on their website so you know what you're getting into. And I can order them through Parts Unlimited. I just wish someone had the rates for the HPD violet that everyone seems to be using with good results.

 

the rear white spring is a replacement for the red factory spring, I would think you would want to go stiffer.

 

Speedwerx said that the stock silver spring is rated at 20-55. I see the white EPI is a 32-63. I figured this would be the next step stiffer. If someone can stear me in the right direction, I would appreciate it. Thanks.
