Joel,

You might go over to www.SaleenClubofAmerica.com and ask some of those guys in the forum.. Man they know their Saleens inside out, and then some. Or at www.SaleenPower.com

Dale in San Antonio

well thats iffy. If the springs are the same as the 87-88, then its about a 700front/290rear specific rate spring, equivalent of H&R's race spring. At some point in the fox body years they went to progressive rates which are a bit smoother riding, but dont handle quite as well. Those would be more of at floating 640-700ish front and 240-280 rear...equivalent of the current eibachs that are considered stiffer (dont know which ones of the 2 offered)

Saleen had told me way back, they don't give out their spring rates.

1987 thru 1989 Saleen's (excluding SSC's) had specific rate springs with a front rating of 650 lbs. and rear rating of 300 lbs.

I got this off the internet a few years ago. I hope this helps you.
