When I did mine I just left a 1 inch gap between the end of the thread on the coilover and the spring platform/nut. Might require a bit of trial and error to get right.
Ive got just the VR, maybe a daily driver Passat Estate soon. My bro has just bought a '51 plate MK4 Golf 1.8T. Yeah, too right that Passat corners! lol :-D
