I think you should consider a set of BBS VZs from GNJ Motorsport. For the sake of just over £200 you can have a genuine set of BBSs. Seems a bit of a no brainer reallyhttp://www.mk5golfgti.co.uk/forum/index.php/topic,57937.0.html
Plus they will be stronger, lighter and better looking
IMO keep monzas cos genuine standard wheels are better than fake bbs but some people have different views on this subject
