Hey everyone,

I have an X reg 323i saloon with some standard, plain 16" alloys. Was thinking of getting some nicer and slightly bigger alloys like the M sport range or Alpina style. Don't want to go too big (18" max). Just wondering what diameter and width I could go to without dropping the suspension or rolling the arches etc.

Just want to buy them and fit them but dont want it to look lke its a 4x4.

Any help appreciated.
