>> I have also driven a golf with a setup you mentioned
I didnt explain the whole set up... :) Yes, It will be very loose in the rear until warm but also you have to do a lot to the rear to stop the beam from twisting, bending, and the bushings from slopping around. If you dont it will be a mess back there. You've seen my posts here about the rear beam anti-toe linkage? That and spherical bearings and things that are also not legal in IT are required to get it "nailed" back there.
