SPECIFICATIONS
The BMW Pre-Preg Carbon Fiber RS Style Rear Diffuser for the G80/G81 M3 and G82/G83 M4 is a true track-focused aerodynamic component designed to go far beyond a standard cosmetic diffuser. This system comes in 7 individual pieces that extend through the rear underbody, forming a complete diffuser assembly rather than just a rear bumper trim. It is currently one of the only properly track-oriented diffuser setups available for this platform, engineered with functional underside strakes that guide and accelerate underbody airflow for improved stability at speed.
Manufactured from pre-preg carbon fiber, the diffuser delivers exceptional strength with minimal weight while maintaining precise fitment. The extended undertray design helps manage airflow exiting from beneath the vehicle, supporting aerodynamic balance when paired with a front splitter and rear wing. This is not just a styling upgrade – it is a serious motorsport component built for drivers who want genuine underbody aero performance from their G8X platform.

TORAYCA™ is a carbon fiber material made by Toray Industries in Japan, its the same company that supplies carbon to brands like Lamborghini, McLaren, Aston Martin, and even Ferrari. It’s the real deal used in supercars, race cars, and aerospace builds where strength, weight, and heat resistance actually matter.
We use genuine Japanese TORAYCA™ Carbon Fiber in all our wet and dry carbon parts. Why? Because it’s lighter, stronger, and more reliable than the cheap composite blends flooding the market from Aliexpress. TORAYCA™ holds up under pressure, keeps its shape over time, and doesn’t fade or fray like lower-grade alternatives.
This is the carbon you use when performance isn’t optional. If you're building a car that turns heads and doesn’t cut corners, TORAYCA™ is the standard.
And it’s the only carbon we trust.

Dry carbon fiber is the premier choice, being 70% lighter than wet carbon and constructed entirely from carbon material, providing a distinct, symmetrical weave. Wet carbon fiber, while slightly heavier, is also high quality and involves applying carbon material onto a mold. Both options offer excellent performance and aesthetic appeal.
