New E46 M3 Street Flow Rear Diffuser

The E46 M3 is an amazing looking car right out of the box but a common BMW issue is the height of the front vs rear bumpers. Dating as far back as the E30, BMW front bumpers have been much lower to the ground than the rear, and the E46 M3 suffers the same fate. This results in the rear bumper appearing incomplete, especially on lowered BMWs. Our add-on diffuser is a unique option for balancing out the rear bumper with the height of the front bumper for that level to ground appearance.
