BMW F95, X5M LCI Carbon Fibre JC Style Rear Diffuser

BMW F95, X5M LCI Carbon Fibre JC Style Rear Diffuser

Complete the rear of your LCI F95 X5M with the JC Style Carbon Fibre Rear Diffuser, a three-piece lower rear upgrade built around two large integrated exhaust surrounds that frame the quad tips and give the car a noticeably wider, lower presence.

Manufactured from premium carbon fibre with a high-gloss twill finish, the kit comprises the main diffuser panel and a pair of separate lower side extensions. The exhaust surrounds are formed as part of the main panel rather than added afterwards, and the whole assembly is shaped to integrate with the factory LCI rear bumper.

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

Key Features

Premium Carbon Fibre Construction

Manufactured from premium carbon fibre with a deep gloss finish that holds its lustre across the large flat surfaces of this design.

Three Piece Design

Supplied as a main diffuser panel plus two lower side extensions, allowing each section to follow the bumper contour independently for a closer fit.

Integrated Exhaust Surrounds

Large rectangular 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 JC Style Design

A wide, squared-off profile that emphasises the width of the LCI rear bumper and gives the X5M a more planted look.

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 F95 X5M rear bumper, following the original contours and mounting locations.

Performance Benefits

Gives the rear of the X5M a wider, lower and more aggressive presence while retaining an OEM+ finish.

Improved Aerodynamic Profile

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

Lightweight Exterior Upgrade

Carbon fibre construction keeps added mass low across a large rear panel.

Completes Your Carbon Fibre Build

Matches the weave and finish of the rest of the Proven Performance Parts F95 carbon range for a consistent exterior package.

Please Note

Professional installation is strongly recommended.

Designed specifically for the LCI F95 X5M 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.
