BMW F91/F92, M8 Carbon Fibre SQ Style Side Skirts

BMW F91/F92, M8 Carbon Fibre SQ Style Side Skirts

Complete the profile of your M8 with the SQ Style Carbon Fibre Side Skirts, a pair of sill extensions that lower the visual line along the flanks and tie the front and rear treatments together.

Manufactured from dry carbon fibre with a high-gloss twill finish, each skirt runs the full length of the sill and rises at the rear into a raised winglet that kicks up ahead of the rear arch. The leading edge tapers to a fine point so the extension appears to grow out of the body rather than sit on it.

They suit an owner who has already addressed the front and rear and wants the side profile to match, and they are the piece that makes a carbon package read as deliberate rather than assembled.

Key Features

Dry Carbon Fibre Construction

Manufactured using a dry carbon process, chosen for its rigidity across a panel of this length and the consistency of its finish.

Raised Rear Winglet

Each skirt lifts into a defined winglet ahead of the rear arch, giving the side profile a motorsport reference point rather than a flat extension.

Supplied as a Pair

Left and right sections are supplied together, moulded as mirrored parts so the car reads the same from either side.

Pre-Drilled Mounting Points

Mounting tabs are formed into the moulding at the factory locations, so each skirt locates against the sill without fabrication.

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 M8 sill, following the original body line.

Performance Benefits

Enhanced Side Profile

Lowers the visual line along the flanks and makes the car look wider and more planted from side on.

Improved Aerodynamic Profile

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

Lightweight Exterior Upgrade

Carbon fibre construction keeps added mass low across a long panel.

Completes Your Carbon Fibre Build

The side profile is what ties a front lip and rear diffuser together; without it a carbon package reads as unfinished.

Vehicle Fitment

BMW F91 M8 / M8 Competition Convertible (2019+)

BMW F92 M8 / M8 Competition Coupe (2019+)

The supplier specifies the Coupe and Convertible only. The F93 Gran Coupe has a longer four-door sill and is not covered.

Please Note

Professional installation is strongly recommended.

Designed for the Coupe and Convertible sill. It is not designed to fit the F93 Gran Coupe, which has a longer four-door sill.

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

Side skirts sit low on the car and are exposed to kerbs and driveways. Ride height and driving style should be considered before fitting.

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