I went for new wheels - BBS SR in 8.5x19 ET46.
Fill the arches spot on.
I'm running 235/35R19 but I think (you'd need to check) 225/35R19 should also be fine on them (although you might get a little bit of a stretched look).
I did much the same but also had spacers when running the originals.
Firstly the BBS's were tried from my old MK6.
Then those were changed for something slightly more OEM looking.
Then I realised I needed a bit of drive to the rear wheels to tame the rather non OEM power.
Which meant I'd need new shoes to go with the new frock...
Gnasher - each time you post that image it changes my mind on white GTIs as generally I don't like them, but that looks spot on.
Admit it Watts, there is really only one choice of shade for ANY mk7...
