Adex G8X OEM Style Rear Splitter Dry Carbon Fiber

An OEM-style dry carbon rear splitter that swaps your G80 M3 or G82 M4 lower rear splitter for genuine carbon — the same clean factory lines, far less weight.

Why owners choose it

• Genuine dry carbon — autoclave-cured dry carbon fiber with a UV-stable gloss clear coat.
• Factory-look upgrade — keeps the OEM shape and fitment, just in real carbon.
• Direct replacement — bolts on in place of the stock rear splitter using factory points.
• Track-ready finish — tight weave, deep gloss, built to last.

Fitment: BMW G80 M3, G82 M4 (2021+). Select your model.

Finish: Gloss dry carbon fiber.

Genuine autoclaved prepreg dry carbon fiber in a deep 2x2 twill weave, cured under heat and pressure so the panel is lighter and stiffer than wet-layup carbon. Finished with a UV-stable clear coat that resists yellowing, over an OEM-grade mould for a factory-line fit.
