I'm just curious, I know my 87 Saleen has Specific rate springs but I'm curious if anyone knows what the rates are? Also I found a set of 91 Saleen progressive rate springs for a deal and I'm also wondering what the rates were for the 91 Saleens. Anyone know what the rates are for these two years? The specific rates are not very forgiving on rough roads so I'm considering changing to the progressive rate springs.
