Give your BMW 4 Series the sharp, motorsport-inspired finish it deserves. These gloss black rear spats from BLAK by CT Carbon are a premium exterior styling upgrade for G22 Coupe and G23 Convertible models from 2020 onwards. Precision made from durable ABS and finished in a deep piano black, they deliver a cleaner, wider-looking tail end that ties in perfectly with factory Shadowline trim and other black styling accents.

We have fitted these in our own builds and for customers across the UK. The feedback is consistent: great fit, superb gloss, and a transformative look without being over the top. If you want that stealthy rear apron effect with an OEM-plus vibe, this is the upgrade.
