Nothing says performance like aggressive body lines and nobody knows how to accentuate those lines quite like ECS. The factory M-sport rear bumper was an excellent accent to an already breathtaking body. This "finned" diffuser takes it to the next level by bringing race inspired looks to your street car.
This diffuser adds to aggressive styling of your G30's body while still maintaining the sleek lines BMWs are so famous for. Installing over you vehicles rear bumper makes installation a snap and you'll be elated with just how proper the fit and finish really is.
