> Good aftermarket suspension should last a nominally shorter time that OEM, under much harsher driving conditions, since they tend to be overbuilt. As for _JDM_ type coilovers… certain Tein, Ksport, Omnipower, and their ilk, they have significantly reduced life. The problem lies in the stack valve design. Over time the wear on the outer seals degrade far faster than OEM, and are not user serviceable. It should be pointed out that a lot of the decreased wear is from people running them too low, out of the range of efficient dampening for which they were designed. They can be rehabbed, but most of the time it isn’t worth it (costwise)

you should change your name to “The Wizard”…shit man how do you know all this stuff :bowdown:
