Heads-up on cancellations & returns: if you cancel an order or return an item, you won't get back 100% of what you paid. We apply a 10% restocking fee, the outbound shipping is non-refundable, and we have to pass on Shopify / PayPal payment processing fees; these aren't returned to us when we refund you. International orders also lose on exchange-rate spread in both directions. If the original packaging is damaged or missing, a reboxing charge applies. For international orders specifically, if you refuse to pay our shipping invoice or supply a prepaid label after placing the order, the same deductions apply. We're upfront about this — please be sure of your purchase before ordering.

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.
Why choose this upgrade
- Transforms the rear profile with a purposeful, performance look
- Premium materials and construction for longevity and consistent weave
- OEM-plus aesthetics that complement factory body lines
- Excellent feedback from enthusiasts on fit, finish and appearance
