Upgrade your G8X profile with CT Carbon rocker extensions
Transform the side profile of your 2021-on M3 with CT Carbon aero side sills. These full replacement rocker trims swap the factory black plastic pieces for ultra lightweight pre-preg carbon, delivering a premium finish and a more aggressive, motorsport look along the lower doors.
If you’re searching for BMW G8X side blades, rocker panel extensions, aero sills, side skirt replacements, side splitters or a performance styling upgrade for your M3, this CT styling piece is the perfect choice. Expect a clean OE-style fit with a sharp, purposeful stance that complements the car’s lines.
Compatibility
- BMW M3 G80 saloon 2021 onwards
- BMW M3 G81 Touring estate 2021 onwards
Why enthusiasts choose these side sills
- Pre-preg carbon construction for an ultra light, rigid result
- Full replacement design rather than stick-on trims
- Directly replaces the OE black plastic rocker covers
- Model-specific moulding for tidy panel gaps and a factory-style finish
- Enhances visual width and lowers the car’s side profile for a more aggressive stance
We have installed these for customers at MJ Modifications and the feedback has been excellent. Fit and finish are spot on, and the upgrade instantly elevates the G8X’s presence on the road.
