This E46 carbon fiber riser is also known as a front lip or air dam and is part of a complete front downforce package.
The E46 M3 front bumper does not have a flat front lower edge, so it is difficult to install a splitter and have it seal properly to the bumper. This all carbon fiber riser follows the contour of the lower edge of the factory bumper and provides a smooth and flat surface to mate your splitter to.
We have confirmed fitment on both factory OEM M3 bumpers as well as the “M3 Style” bumpers popular with non-M E46’s.
This is a rugged race quality part, not just a piece of flare for the nose of your car.
Installation requires attaching to the bumper, we recommend large expanding rivets designed for use with soft plastics.
