The Suvneer Motorsports™ G8X M3/M4 Carbon Fiber Rear Diffuser Undertray is a high-performance aerodynamic upgrade engineered for BMW G80 M3 and G82/G83 M4 models. Designed to enhance rear-end stability and airflow efficiency, this undertray is crafted from premium carbon fiber, ensuring a perfect blend of lightweight construction, durability, and motorsport-inspired aesthetics.

By extending the aerodynamic profile of your factory diffuser, the undertray helps reduce turbulence and increase downforce, improving high-speed stability and cornering performance. The Suvneer Motorsports™ G8X M3/M4 Carbon Fiber Rear Diffuser Undertray is only intended to be used with the Suvneer. Its aggressive, track-ready design complements the bold styling of the G8X M3/M4 while seamlessly integrating with OEM and aftermarket rear diffusers.

Key Features:

  • Material: High-quality carbon fiber
  • Lightweight: Carbon fiber construction reduces weight while maintaining strength.
  • Aerodynamic Enhancement: Improves airflow and downforce for better stability.
  • Sleek Design: Adds a sporty and aggressive look to your G8X M3/M4.

Compatibility:

  • G8X M3/M4 2020-Current
