I saw you say they were progressive,
what I'm trying to learn is if the:
285 lb/inch Front Progressive
450 lb/inch Rear Progressive
I'm trying to clarify if the numbers you listed are top/bottom or middle of that progressive range.
example, the eibach pro kit rears are progressive from 280-326. you couldn't just call them 326lb/inch because that doesn't let you know whether that's the softest part of the spring rate or whether it's the stiffest.
