Upgrade the rear profile of your BMW M3 or M4 with our G8X M Performance-Style Rear Diffuser V1, designed to add a cleaner, more aggressive M Performance-inspired finish to the factory rear bumper.
The V1 design features a wide, sculpted profile with three pronounced vertical centre fins, creating additional depth and definition through the centre of the rear bumper. The raised outer sections flow around the factory quad-exhaust layout, maintaining the signature G8X rear-end appearance while giving the lower bumper a sharper and more performance-focused finish.
Available in Gloss Black, Carbon Lookalike, or Real Carbon Fibre.
