Overview

The G80 M3 and G82 M4 handle well and carry a strong turbocharged inline-six, but BMW left room for aerodynamic improvement. A front splitter helps balance larger rear aerodynamic systems and adds real front-end grip.

Front splitters produce downforce by creating a large pressure delta between their top and bottom surfaces. This kit adds carbon nylon diffuser sections underneath to work the airflow harder than a flat blade alone, and mounts through a steel structural support tube and bracket set for a rigid install.

The blades are carbon polyweave, the same material used in top-tier motorsport — not brittle like carbon fiber or ABS, and it won't grab and bend under the car like aluminum.
