BMW F96, X6M LCI Carbon Fibre V.1 Rear Diffuser

BMW F96, X6M LCI Carbon Fibre V.1 Rear Diffuser

Refine the rear of your LCI F96 X6M with the V.1 Carbon Fibre Rear Diffuser, a four-piece lower rear assembly that frames the quad exhaust exits and gives the car a wider, lower and more deliberate stance.

Manufactured from dry carbon fibre with a high-gloss twill finish, the kit comprises the main diffuser panel, a pair of lower side extensions and a small centre trim piece. Large squared exhaust surrounds are formed into the main panel, and pre-drilled mounting points follow the factory locations so the assembly sits against the original LCI rear bumper.

It suits a fully specified street or show build where the rear of the car is the final piece of a coordinated carbon package.

Key Features

Dry Carbon Fibre Construction

Manufactured using a dry carbon process, chosen for its rigidity and its consistent finish across the large flat surfaces of this design.

Four Piece Design

Main diffuser panel, two lower side extensions and a centre trim piece, so each section can follow the bumper contour independently for a closer fit.

Integrated Exhaust Surrounds

Squared surrounds are formed into the main panel and frame the quad exhaust exits, tying the tips into the diffuser as a single design element.

Aggressive V.1 Styling

A wide, angular profile with stepped lower edges that emphasises the width of the LCI rear bumper.

High Gloss Twill Finish

A clear gloss finish over a consistent twill weave, matched to the look of factory BMW M Performance carbon components.

Precision Fitment

Shaped specifically for the LCI F96 X6M rear bumper, with mounting points following the original locations.

Designed to complement the vehicle's aerodynamic profile and help manage airflow leaving the rear of the car.

Please Note

Professional installation is strongly recommended.

Designed specifically for the LCI F96 X6M from the 2023 model year. It is not designed to fit the pre-LCI rear bumper.

Minor preparation, alignment or adjustment may be required during installation to achieve optimal fitment.

Factory hardware, fasteners, sensors or trim may need to be transferred from the original component.

Due to the nature of carbon-fibre manufacturing, slight variations in weave pattern may occur between products.
