i'm looking for non-variable, non-progressive springs for the rear. i've experimented with all kinds of rear springs and want a solid rate rear now. i've googled and yahoo'd until my eyes popped out and have searched numerous forums and cannot find anyone who makes them. my neighbor has a set of no-name F-1 style springs that someone was experimenting with a few years ago, and they were awesome, but he wouldnt sell when he sold his car. they were solid rate and stiff. that's what i'm looking for. i'm not necessarily looking for lowering, but if i have to i'll go that route too. i have hal shocks on all 4 corners with the 325lb fronts. car will be primarily street driven with occasional track visits.

thanks for your help

look at the 5" pigtail springs.

Come in any free height or spring rate you might need ...

if i get a stiffer spring for the rear, wont i have to get it shorter so it doesnt increase the ride height?

felton316

It depends on how much stiffer the new spring is. But, in general you will need a shorter spring because the stiffer one will not compress as much.

so a 5" by 11" at 125lb sound about right? or should i go with a 10" rear spring at 150 lbs?

A 25# step is pretty small for a whole inch. For what its worth, I'm currently running a 150# 10" long spring(with stock rubber isolater) and my rear fender height is ~26" from the ground. Under heavy cornering the 315's will touch the fender.

Here's another place to try, just in case.
Again, look for 5" pigtail.
