Another quick spring rate question.
 

Does anyone know the spring rate of the M030 springs?
Thanks,
Tony

for what model and year? there are different ones - as an example:

924S and 944 up to MY 86 were 140#
944S2 and Turbo were 160#

these were also different lengths

944 S2's. I am upgrading the suspension on my '83NA and I already have the 25.5mm torsion bars. Now I am trying to find out if the 200# springs from Weltmeister would be a good bet with those torsion bars in order to keep the suspension balanced.

25.5 torsions are 175lb wheel rate

depending on the weight distribution, the 200lb springs may be a touch too stiff for the ultimate balance - if the rear is light though, they would work well
