BMW G87, M2 Carbon Fibre SQ Style Rear Diffuser

BMW G87 M2 Carbon Fibre SQ Style Rear Diffuser

Replace the lower rear valance on your G87 M2 with this SQ Style Rear Diffuser — a three-piece carbon fibre kit made up of a full-width centre diffuser and a pair of outer corner blades.

Where the OEM Style diffuser follows BMW's own shape, the SQ profile goes further. Two large hexagonal outlets frame the exhaust tips, the centre section carries a raised strake between them, and the outer blades wrap around the corners of the bumper and turn up sharply at the arches. It is the more aggressive of the two G87 diffusers we carry and the one that changes the car's stance from directly behind.

The G87 has one of the boxiest rear bumpers in the current M range. This kit fills the whole lower section with carbon rather than just the middle, which is what makes the rear read lower and wider rather than simply darker.

All three pieces are carbon fibre with a high-gloss twill weave under a UV-protected clear coat, moulded to the contour of the factory G87 rear bumper and fitted at the existing lower valance locations.

Key Features

Three Piece Kit

A full-width centre diffuser plus two outer corner blades, so the whole lower rear is covered.

SQ Hexagonal Outlet Profile

Two large hexagonal openings frame the exhaust tips, the detail that defines the SQ shape.

Wrapped Corner Blades

The outer pieces turn up sharply at the arches, widening the rear rather than stopping at the exhaust.

Carbon Fibre Construction

Carbon fibre with a consistent twill weave under a high-gloss clear coat, matched to the look of the rest of the G87 carbon range.

UV Protected Finish

A high-gloss coating that resists yellowing and holds its depth under Australian sun.

Factory Mounting Points

Moulded to the contour of the standard G87 rear bumper and fitted at the existing lower valance locations.

Vehicle Fitment

Please Note

Professional installation is strongly recommended. The three pieces need to be aligned to each other and to the bumper before any fixing is made permanent.

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