OEM Style Rear Splitter Prepreg Carbon Fiber | G8X BMW G80 M3 & G82/83 M4

Sharpen the rear end of your BMW G80 M3 with this OEM-style rear splitter, a carbon fiber add-on built to mirror the factory rear valance shape rather than reinvent it. Instead of a bolt-on look, it tucks into the stock rear bumper contour so the finished result reads like a factory option, just with real carbon fiber texture peeking out below the diffuser. It's the kind of subtle upgrade that ties your rear fascia together and gives the back of the car the same aggressive, finished look as the front splitter and side skirts.

Each splitter is molded from prepreg carbon fiber, cured under heat and pressure for a rigid, lightweight panel with a consistent weave and a durable clear coat that resists fading and chipping. It's designed as a direct fit for the BMW G80 M3 rear bumper, using the factory mounting points for a straightforward install without cutting or trimming. Every splitter ships as a complete, ready-to-install piece, hardware included, so it bolts on for a clean factory-style result.
