We offer a diffuser, the addition of the rear bumper. It was designed to give the car a racing character, its optical reduction and a unique tuning element in your car!The diffuser has been designed so that you can personalize it with your car and individual needs. It gives us the possibility to mount 2 or 3 middle wings in any chosen spacing. In addition, the 2 extreme elements are separate elements, which gives another possibility of their any setting.Why is the diffuser called universal?The answer is simple, because its mounting part is flat, which makes it compatible with a large number of bumpers, not just those from the BMW range. Everyone who has at least some manual skills is able to fold the diffuser.
