i have done a lot of searching thru topics on here and it seems that for a 3200# metric car the average spring rate in the back is 250#lr and 200#rr. i talked to a local chassis builder that has been doing this for about 10 years and he told me to run 350#lr and 300#rr. this seems a little heavy to me.i would like to know what everybody else thinks of this. the track is a 1/4 mile semi-banked track.(thats how they word it) thanks for the info!

We run 250lr and 200 rr. This seems to differ almost no matter who you ask. See what works for you, on your track.

You are real close where you are at.I have a metric frame and it weighs 3050 pds.I run a 1200rf 1050lf,250lr,and 225 or 200rr depending on how rough the track is.You also need a good set of shocks, I prefer afco, but bilstein,and others also make good racing shocks for street stocks.

depends on how the track is at feature time if it is slick and smooth then 175 rr and 200 lr works really good also for front springs i run 1000 rf and 900 lf

I went with a 300# LR and a 250# RR. But our track has a 3500# minimum and there is about 500# of lead right over the rearend.
350# is way to heavy for a 3200# car.
