The sizes above work well if the goal is to keep the factory tire sizes - 255/40-18 front and 275/40-18 rear.
For most enthusiasts, wider wheel widths are desired to support wider tires, and to achieve a more flush fitment. Our most popular F8X M3/M4 staggered fitment is either of the following:
18x9.5" ET22 - 275/35-18
18x11" ET44 - 305/35-18
or
18x10" ET25 - 275/35-18
18x11" ET44 - 305/35-18
As you can see, there are two front wheel options. Both work very well, however the 9.5" wheel supplies enthusiasts with more inner strut clearance - necessary if you are running KW suspension or a sleeve kit that takes up a lot of room on the inside. The 10" front wheel option supplies enthusiasts with maximum sidewall support, and work well with stock suspension, lowering springs or coilovers that do not compromise inner clearance (linear springs).
Here is a very informative and detailed thread on the development of our F8X specific 18x11" rear wheels - LINK.

Hi Ryan,
Thanks for the explanation! As I am running a KW kit set quite low I think my dealer did not want to take any risks (he also knows I don't tend to brake a lot for speed bumps). He ordered Michelin PSS 265/40 for the front and 295/35 for the rear on the rim sizes I mentioned. A bonus is that I will be able to pass MOT with these rims. I think I will give it a try and see how they perform on the track as I am not looking for maximum wide stance per se.
Thanks for the assistance!
