And you have bought nothing but lemons since your last M so get back in the camp and stop being silly lurking around outside with talk of cross dressing BUY AN M (obviously next year when you have funds) and stop pretending your going to buy something else....
I have 195/45/16's on mine, it used to tramline a bit but the coilovers have sorted that. IMO 16's are the perfect size for an M. Having said that, if, according to your thread on mgzs kit, you're not going too low the 17's will fill the arches perfectly, have a look at Tom's deck, he's just changed from 45 to 40 profile 17's.
LOL i don't know why but i like the route your build is going looks quite similar to another M i absolutely love but at the same time completely different
