I am looking at a set of KW V3 coilovers with MM camber plates that have 15k miles on them for $750. Is that a good price and how worn out are they with 15k miles? Thanks!
I go with the simple 30-60k miles after normal abuse. Tracking the car, winter driving....etc will cause accelerated wear and should be rebuilt earlier. Race teams have them rebuilt more than that. Go until they feel loose, tighten the damping up and go from there. If they get to the end of the damping knob or if they are leaking, send them back and have them rebuilt.
