I spent about $600.00 last year with a local suspension guy getting a setup ( not sure what he did, new springs, valves, etc. ? ) Although Im happy, I do have some extra $$ to spend and was thinking about going with factory connection. So my question is, although my suspension has already been modified by a local suspension guy, will I notice a difference if I get factory connection work done to it? Im knew to suspension so sorry for the lamense terms.
