^^^ totaly agree, i dropped mine (its a mk2 gti though) 40 to start off with, no problems at all. its now wound down stupidly low on coilovers and the only rubbing i get is when i've got my split rims on the back as they are wider. and even then its not a big problem, get it down 40mm!!
i'd get a set of winter wheels if your going mirror polished, like veedubgti16v said, cleaning polished bbs splits is a nightmare!!! at least you would be able to take a buffer to yours fairly easily!
