SPECIFICATIONS
The RZ-R SPA300 Rear Wing is the primary aerodynamic contributor within RZ’s complete aero system for the BMW M3 G80, engineered from the ground up to deliver serious, measurable performance. When paired with the full RZ aero kit, the system has been CFD-optimised to generate over 1,130 kg / 2,500 lb of total downforce at 180 mph (290 km/h), with the SPA300 rear wing providing the dominant portion of rear axle load. This is not an off-the-shelf wing profile – it uses a bespoke airfoil developed specifically for the G80 chassis to maximise downforce while maintaining controlled drag and stability at high speed.
Development began with advanced 2D machine-learning analysis, evaluating hundreds of airfoil profiles to build a detailed aerodynamic performance database. The selected profile was then refined using state-of-the-art 3D CFD, including Hybrid LES simulations to accurately predict flow separation and behaviour across varying ride heights, rake angles, and wing settings. This ensures the wing maintains aerodynamic integrity under real track conditions, not just idealised simulations.
The SPA300 features a high degree of adjustability, allowing precise aero-balance tuning to suit different tracks, setups, and driving styles. This adjustability is critical to working in harmony with the front splitter, underbody, and diffuser, giving drivers confidence to push deeper into high-speed corners. Constructed from aerospace-grade pre-preg carbon fiber, the wing delivers exceptional strength with minimal weight, while its aggressive profile gives the M3 a true race-spec presence backed by real aerodynamic data, not marketing claims.
Key Features:
- Genuine Japanese TORAYCA™ carbon fiber construction - ultra-lightweight with stunning 2×2 gloss twill weave for strength and finish
- Aerodynamically engineered with advanced CFD and wind-tunnel insights for measurable downforce and high-speed stability on track and road
- Designed as an integrated performance aero system to optimize airflow, reduce drag, and improve grip through corners.
- Functional, race-proven components offering real performance gains, not just cosmetics - the best choice for serious enthusiasts and track drivers

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.
