[Novette_71]

(just recognized this is the wrong place how do i move it to chassis? sorry.)

guys,

please help me.

i am getting frustrated with making phone calls around the world figuring out what to do with my coil overs.

i have 1 1971 chevy nova, estimated 1650 pounds on the front, 1450 on the back.

i have the wayne due C4 IRS setup front and rear.

front : ball joint to subframe 12.8", shock to subframe 10.24 ", shock angled 20°.

rear : ball joint to subframe 18.3", shock to subframe 11.2 ", shock angled 26°.

I wanted to use the QA1 double adjustable coil overs, but just heard from someone else QA1 is crap except for drag racing. can anyone confirm this or has good experiences with their products ?

my ride needs to be firm, but not harsh, should be able to do some good autocross, from seeing badpenny perform i would say that looks right for me.

from my feeling i would say i want 500# springs front and whatever fits to that in the rear .... when i tried these (a/b)^2 formulas the numbers where all non-sense dont know where i screwed up.

i have a 1994 viper with a paxton and a K&W stage III coil-overs and that set-up is pretty nice , maybe slightly less firm. maybe this helps someone for comparison.

if qa1 is crap, what would you recommend as a great product ?

thanks for your help.
