coilover shocks

[terrellautosports]

any of you guys that are running these i need your help. i need to know what spring rate you are running, what length spring, what shock compression and stroke? and if anyone knows where i can get a good set as cheap as possible. or if any of you have a set for sale.
any help will be appreciated.
i am getting everything lined up to use coilovers on an IRS for my wifes truck.
it is a corvette rear end.

thanks in advance.

There are ways to calculate the correct spring rate to use. It's based on the weight on each wheel and the distance from the pivot point of the control arm. I think QA1 has the formula on their website. I would also call the company you are going to buy them from.
I saw a pretty good deal for adjustable QA1s on racingjunk. I think QA1s are the best for the money. The varishock is probably the best but those will set you back more then $700 a pair.
