We all know how popular the previous M3’s have been with tuners around the world and I am quite positive that the current M3 and M4 will be just as big, if not bigger. Hamann Motorsport showed us a peak at their big bodied BMW X5 yesterday and now we get some shots of an Austin Yellow BMW M4 wearing some of their aftermarket wheels. All three of the wheels shown below are 21 inches which give it a beefier appearance since the standard wheels are either 18 or 19 inch. Which set would you choose or would you be like me and stick with stock?
