There was a huge thread on here I was reading yesterday or the day before and it seems to have just disappeared. But in simple terms; DO NOT machine wheels to change offset, even a 2mm shave could destroy the integrity of the wheel completely. I'd remove the springs if the tires are that important to you or trade them with somebody for 285/30.
- spacers won't solve the issue cos he needs a higher offset not lower.
EDIT - found the link, guess it wasn't even on here. Hopefully admin doesn't remove this; http://forums.vwvortex.com/showthrea...lling-material
