Basic Carbon rear valance insert for BMW F80 F82 F83 M3 and M4

Key benefits

• Genuine carbon fibre with a deep gloss clear lacquer for a premium, high-shine appearance.
• Tailored around the original bumper profile of the F80, F82 and F83 for a factory-style fit and clean bodyline integration.
• Quad tailpipe openings to suit standard M3 and M4 exhaust layouts.
• Lightweight yet rigid construction that elevates the rear profile with defined strakes.
• Tried in-house by MJ Modifications and fitted for customers with excellent feedback on fit and finish.

Construction and finish

Produced in high quality carbon fibre and finished in a smooth, high-gloss clear coat that highlights the weave and helps resist weathering. The result is a durable, premium-looking rear apron insert that enhances the car’s presence without looking out of place.
