Carbon rear bumper winglets for BMW G8X M3 and M4

Give your BMW G80 G81 M3 or G82 G83 M4 a sharper, race-bred rear end with these carbon fibre rear bumper winglets. Crafted from prepreg dry carbon in a 2x2 twill weave, this rear spat set adds purposeful aero styling, a premium finish and a factory-like fit that follows the G8X body lines beautifully.

Engineered for the G8X platform and modelled in CAD to align with factory locations, these rear fins use the original-style fixings for a clean, quality install and an OEM-style appearance. The result is a more aggressive stance and cohesive rear profile that pairs perfectly with a carbon rear diffuser and side skirt extensions.

• 2x2 twill weave for a true M-inspired aesthetic that matches other carbon trim
• Design enhances the rear apron with a motorsport look while retaining factory lines
• CAD-developed to work with stock-style fixing points for a tight, flush fit
