Complete the side profile of your BMW F97 X3M or F98 X4M with these Carbon Fibre Side Skirts V.1 — a pair of full-length extensions engineered to lower the visual stance and tie the front and rear styling together.
The V.1 profile runs the full length of the sill with a clean lower edge and sculpted leading and trailing corners, closing the visual gap between the wheels and giving the car a longer, lower look from the side.
Constructed from carbon fibre with a high-gloss exposed weave, they offer lightweight strength and a deep, consistent finish that pairs naturally with other carbon fibre exterior components.
Whether you are building a clean street car or a complete carbon fibre exterior package, these side skirts are the piece that makes a front lip and rear diffuser read as one design rather than separate additions.
