Can anyone help me out with converting these? First one is GC180.64.44 then GC200.64.58.

 

7" free length, 2.5" ID, 250lbs/in
8" free length, 2.5" ID, 330lbs/in

How do I tell what my spring rates are?
Ground Control sells Eibach Race Springs (ERS) which are labelled by 3 different values in the following convention: length . diameter . spring rate. However, ERS will come labelled in either Metric (mm.mm.N/m) or English (inchx100.inchx100.lbs/inch) units. 180.64.61 is the same thing as 700.250.350. The conversion from Metric to English is (/.254, /.254, x5.7) "/" means "divide by", "x" means "multiply by".
