Eibach Sportline 4.1060 Spring Rate

[97egl]

Does anyone know where to find the specs for Eibach 4.1060 spring rates? I can find them for sale online but can't find anything other than the drop height.

I don't have 1g numbers available to me but you might find this information of some use:

97-99 OEM Stock AWD
Front: 246 lbs/in
Rear: 151 lbs/in

Eibach Sportlines for 97-99 AWD
Front: 286 lbs/in
Rear: 146 lbs/in

1990 OEM Stock AWD
Front: 146 lbs/in
Rear: 140 lbs/in

So while the direct answer is not available to me at this time, we can make an educated guess and the answer is "much too low". And that's not a jab at the excessive lowering provided by Sportlines, but indeed an assessment (although biased) of the expected spring rates for that product.
Making matters worse, not only could the numbers be lower than OEM but the springs are progressive, too, meaning the initial rates are much lower than the max measurement.
