Wheels! Places or websites and sizes

Hi all,

I'm new to this site. Just picked up my M235 the other day. In love with it!

Only problem I have is I'm not a fan of the wheels on it. I have looked around and I think a set of the current M4 style rims in a Saturn black would look perfect.

Only issue is I don't know what size I can fit on the car nor where I could source them. Anyone know of any good places that have replica wheels in Melbourne? Or even a website they would recommend?

I'm thinking 19's would look best but how wide could I go without any rubbing and not a huge loss of ride quality?

Sorry if this has been covered before. I tried searching in other threads but everyone kept talking about spacers and camber and whatnot. I'm not hugely technical with that stuff and I would prefer an easy on off fitment.:)

Thanks!
