I shimmed my quattro about 1.5 behind the collet which I really don't want to do long term and .5 between the nut and bell. The issue with that is you end up with less threads gripping on the clutch nut. Technically it works but there is a lot to go wrong.

Still investigating myself, but interested if someone else has a good fix.
