BMW G90/G99, M5 Carbon Fibre MP Style Rear Diffuser

BMW G90/G99 M5 Carbon Fibre MP Style Rear Diffuser

Finish the rear of your BMW G90 M5 or G99 M5 Touring with this MP Style Rear Diffuser, moulded in dry carbon fibre to replace the plain factory lower valance with a properly aggressive multi-element design.

The standard G90 rear bumper is broad and flat below the exhaust tips, and it is the one area that lets down an otherwise purposeful car. This diffuser fills that space with defined vertical strakes and a stepped lower edge, giving the back of the car the width and intent the front already has.

It is a screw-on replacement for the lower section, supplied with the fixings and with the towing hitch aperture already cut, so nothing needs to be modified or drilled on the car itself.

Manufactured in dry carbon fibre with a gloss clear coat, moulded to the exact contour of the G90 bumper so the panel gaps stay tight and the strakes line up with the exhaust exits.

Key Features

Genuine Dry Carbon Fibre

Real dry carbon construction with a deep gloss clear coat, lighter and stiffer than wet-lay carbon.

MP Style Multi-Element Design

Defined vertical strakes and a stepped lower edge that visually widen the rear of the car.

Towing Hitch Cut-Out

The aperture is moulded in, so a factory tow hitch remains usable without modification.

Moulded to the Factory Bumper

Follows the original contours exactly, so panel gaps stay tight and the strakes align with the exhaust exits.

Screw-On Installation

Fixings are supplied and mount to existing points. No cutting or drilling of the bumper.

Matches the MP Style Front Lip

Designed as the rear half of the same styling language, so front and back read as one kit.

Styling Benefits

• Aggressive, purposeful rear end
• Visually widens the back of the car
• Genuine dry carbon weave that matches other carbon parts
• Retains use of a factory tow hitch
• Fully reversible at resale or end of lease

Please Note

Professional installation is recommended to ensure the diffuser is aligned to the bumper before the fixings are tightened.

Carbon fibre is a natural woven material. Minor variation in weave pattern between pieces is characteristic of the material and not a defect.
