BMW G8X G80 G82 M3 M4 Carbon Fiber LED Rear Center Diffuser

Upgrade your G80 M3 G82 M4 rear end to the ultimate race car look with our latest carbon fiber center diffuser featuring a LED center bar. We've taken the original M Performance design and extended it so the diffuser sits about 1" lower for a more aggressive look. 

The LED can be wired as an "always on" rain light, or can be wired as a brake light. Simple installation and wiring can be performed by tapping 2 wires to the outer taillight.
