Give your M3 a sharper, lower and more purposeful profile with these CT-style carbon side sills. Crafted from premium pre-preg carbon fibre, this full swap kit replaces the factory black plastic rocker trims on the BMW M3 G80 Saloon and G81 Touring from 2021 onwards. Expect a clean OEM+ look, real weight saving and motorsport-inspired styling that matches the aggressive stance of the M3.
We have installed these in-house and the results are superb. Fitment is tight, the weave alignment is excellent and customer feedback has been consistently positive for the finish and the way they transform the car’s side profile.
