Actually you can revalve alot of shocks. I know my friends with stock WRX struts he can buy inserts for his. YOu take the struts off, cut the guts out and install the Koni Inserts.

As far as my shocks I found out today that I do not really need to do it. My Koni Yellows should be good for another 2-3 years with the spring rates I'm running (350f/400r). And my suspension guy said most FWD cars don't need compression adjustment just rebound - because if you make the car too stiff the car can skitter across the pavement instead of absorbing the road.

Revalving means replacing the internals of the shocks cause like any part of the car they can wear out. A worn out shock can cause a car to bounce after it hits a bump. Sort of like many people do with aftermarket springs and stock shocks.

And yes I'm removing everything so I can drive my car in the winter. Corrosion is taking a toll on my exhaust components already (been on the car for 3 years). So I might get them Jet Hot coated. And my suspension is the "PRIME" of my car don't want to ruin those pieces with road salt.
