    Matching Koni SA shocks to e30 M3 spring rates

    I was looking at the Thread above this ( Adjusting Koni yellow) ) and this statement caught my attention:

    Understand that the adjustment on Koni SA shocks controls the rebound rate. It won't make the shooks stiffer to compress, but rather will reduce that speed at which they decompress. For the best handling you want the least rebound damping that is compatible with the spring rates in use. You don't want the wheel to oscillate after compression of the spring, but you want the fastest return of the wheel that doesn't result in bounce to maximize the contact patch.

    Over the winter i am going to upgrade my 90 325i shocks with the standard length Koni SA yellow shocks ( got them from my Pelican connection ) , 1988 e30M3 springs, Ireland adjustable front sway bar and 15 x 7 wheels with 205 50 15 tires. I already have the V2 solid FCAB, poly rear sub frame bushings and new rubber tans/ engine mounts ( its smoother ).

    My question: is there a chart to go off for the best setting of the Koni SA based on your spring rate?
