The G80 BMW M3 Competition is already a formidable machine — 503 hp, standard xDrive or optional RWD, active M differential, and adaptive suspension. For owners who want to match the exterior's appearance to that brutal performance number, here's a systematic carbon fiber upgrade path from first mod to full build.
Stage 1: Quick Wins (Under $500 each)
Carbon Fiber Mirror Covers
Start here. The G80 M3's large side mirrors in carbon fiber immediately signal that this isn't a stock car. 30-minute installation, no tools required.
Carbon Fiber Front Grille Inserts
The grille mesh inserts in carbon fiber darken the front end and eliminate chrome for a more aggressive appearance.
Stage 2: Visual Transformation (Under $1,000 each)
Carbon Fiber Rear Diffuser
The G80 Competition's quad exhaust setup looks even better framed by a carbon fiber diffuser. This is the upgrade that makes the rear of the car look complete.
Carbon Fiber Front Splitter
Adds front downforce and sharpens the nose's visual profile. Especially impactful on the Competition's more aggressive front bumper.
Stage 3: Full Aero Package
Carbon Fiber Trunk Spoiler or Wing
Close out the build with a trunk lip or M4 CSL-inspired trunk wing in carbon fiber. Combine with a front splitter for a balanced aero package that performs at the track as well as it looks on the street.
