Arguably the most aggressive and best selling carbon fiber lip for the E9X OEM M3 bumper is the GT4 lip. This is gorgeous, aggressive and functional. This lip is made with carbon fiber for lightweight and durability. Goes great when paired with the canard (as seen in photos). These will be made to order. please allow a few weeks before you receive it. This does not fit replica 3 series bumpers or any other vehicle. Install is direct bolt onto the bumper.. Remove front bumper and screw into corresponding holes. Holes are already placed on the lip. Please use self tapping screws as well for good measure.
