Shoes can make or break one's outfit if not properly matched. You could say same thing applies to cars. And swapping your wheels out for new ones are probably the easiest way to customise your car's appearance.

SR Auto Group fitted its BMW i3 with a set of PUR LG04 alloy rims with a custom made flat lip and blue screws which are in the same shade as the i3's body trim accents.

Nothing else seems to be changed other than an upgraded suspension which drops the car by a fair bit. I must say the i3 looks properly evil in this form with its wheels flush to the fender!
