BMW M4/4 SERIES G83/G23 CARBON FIBRE SPOILER - CT DESIGN

Carbon rear boot lip for G-series performance models

Give the rear of your car a sharper, motorsport-inspired finish with this premium carbon boot lip by CT Carbon. Built from prepreg carbon and cured in an autoclave for strength, lightness and a deep gloss, it delivers an aggressive OEM-plus look with real aerodynamic presence. We have fitted these ourselves and customer feedback has been outstanding for fitment, weave quality and the high gloss clear coat.

• Prepreg carbon construction for lightweight rigidity and a high-end finish
• Deep gloss clear coat designed to showcase the weave and resist fading
• Precise contours for a clean, factory-style fit and seamless styling
• Subtle aero effect that enhances rear-end stability and road presence
• Track-inspired styling that suits both daily driving and show builds

Compatibility

This carbon boot lip fits the following G-series platforms:

• 2021 onward G82 and G83
• 2021 onward G23 4 Series

Protection when operating the roof

Supplied with discrete rubber bump-stops that should be installed on the boot lid to prevent contact when the convertible roof is in motion, as shown in the final product image.
