Diffuser Installation
$30.00
Upgrade the rear profile of your BMW M3 or M4 with our G8X CSL-Style LED Rear Diffuser V3, featuring a sculpted Real Carbon Fibre design with a distinctive integrated rectangular centre LED brake light.
The V3 design uses a wide, sculpted profile that follows the lower rear bumper and surrounds the factory quad-exhaust configuration. A raised centre section adds additional depth through the middle of the diffuser, while the outer sections extend toward the corners of the bumper for a wider and more integrated appearance.
At the centre sits the defining feature of this design — a large rectangular LED brake light housed directly within the raised centre section. The illuminated centre light adds a distinctive performance-inspired element while remaining cleanly integrated into the overall diffuser design.
Available exclusively in Real Carbon Fibre.
