I don't know if anyone cares, but I found out the spring ratings on the SVT kit with the 1.5 inch drop springs that go with that kit?
I found out what I could about the spring rate on the M-5560-ZXM lowering springs are, after calling like 6 places I found out that the rear is:
Not under pressure they are 12.1 inches, when under pressure down to 5.9 inches the lb rating is 828LB's, and when they are compressed to 6.9 inches the Lb rating is 586lb's.
For the front I got a bit more info, the not under pressure length is 12.4in and the rating is actually two, one is 100lb's per inch and after 2 inch's the Lb rating goes up to 130Lb's per inch.
