I think you may want to change out the struts. I find the airlift rears comfortable in my buddies' mk4s. They all have different struts bilstein, koni, and raceland even. The racelands are definitely the worst out of the group. Not sure if they're making them for te mk4 but airlift will eventually be coming out with a new mkv rear strut that is threaded and adjustable dampening which would be perfect in your situation.
