BMW G90, M5 Carbon Fibre SQ Style Rear Roof Spoiler

BMW G90, M5 Carbon Fibre SQ Style Rear Roof Spoiler

Transform the rear of your G90 M5 with the SQ Style Carbon Fibre Roof Spoiler, a wide blade that mounts above the rear glass and gives the saloon a genuine motorsport silhouette from behind.

Manufactured from dry carbon fibre with a high-gloss twill finish, the spoiler spans the full width of the roofline with a stepped centre section and shaped end plates that wrap down onto the rear pillars. It stands clear of the glass rather than sitting flush, so the change to the car's profile is immediate.

It suits a show-focused or fully specified build, and works alongside a boot ducktail for a layered rear treatment.

Key Features

Dry Carbon Fibre Construction

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

Raised SQ Style Profile

A stepped centre section stands clear of the roofline, creating a defined wing silhouette rather than a flush lip.

Shaped End Plates

Formed ends wrap down onto the rear pillars, tying the spoiler into the body rather than leaving it sitting proud of the roof.

High Gloss Twill Finish

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

Lightweight Construction

Dry carbon keeps the added mass low for a component mounted at the highest point of the car.

Precision Fitment

Shaped specifically for the G90 M5 roofline, following the original contours.

Performance Benefits

Transformed Rear Profile

Alters the car's silhouette rather than detailing it, making it the most visually significant rear upgrade available for the G90.

Improved Aerodynamic Profile

Designed to complement the vehicle's aerodynamic profile and help manage airflow leaving the roof.

Lightweight Exterior Upgrade

Adds significant presence with minimal additional weight for a component of this scale.

Completes Your Carbon Fibre Build

Matches the weave and finish of the rest of the Proven Performance Parts G90 carbon range for a consistent exterior package.

Vehicle Fitment

BMW G90 M5 Sedan (2024+)

Designed for the G90 saloon roofline. It is not designed to fit the G99 M5 Touring.

Please Note

Professional installation is strongly recommended. This component mounts at roof height, and secure fitment is essential.

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

Factory hardware, fasteners 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.
