My stock shocks no longer cut the mustard. I've looked through the threads on suspension upgrades, and from the advice I think I want adjustable damping. I don't want to lower the car (well, not very much anyway) because I need the ground clearance and the roads where I live are rough in places. Koni yellows seem to be highly regarded. Do they work well with the stock springs? My car is a daily driver, but I like to wick it up occasionally.
