Transform the rear profile of your F8X with premium carbon corner extensions
Give your BMW’s rear end a sharper, more aggressive finish with CT Carbon rear corner extensions. Crafted from genuine carbon fibre, these sculpted trims sit on the outer edges of the rear apron to amplify road presence, complement your diffuser, and deliver that race-inspired look enthusiasts want.
Perfectly tailored for the F80 M3 Saloon, F82 M4 Coupé, and F83 M4 Convertible, this upgrade integrates beautifully with the BMW M Performance rear diffuser and adds a V-style diffuser aesthetic at the corners. Lightweight, durable and stunning in person, this is a high-impact exterior styling enhancement that looks factory-fresh yet unmistakably motorsport.
Why enthusiasts choose these rear corner extensions
- Authentic carbon fibre construction for a premium finish and long-lasting durability
- Precision moulded for an OE-style fit on the F8X rear apron
- Complements BMW M Performance diffuser and echoes a V-style edge profile
- Instantly enhances stance and rear-end definition without overhauling the whole bumper
