Product Description
The GR Supra has a uniquely sculpted body designed for both aesthetics and downforce. However, the factory rear bumper leaves considerable space for styling upgrades. A rear diffuser bumper lip fills this area with a more aggressive look while enhancing the way air exits the underbody.
To achieve a more aggressive, track-inspired appearance
To improve rear airflow and aerodynamic stability
To better complement aftermarket exhaust systems
To add visual depth and width to the rear bumper
To protect the bumper’s lower edge from scrapes and debris
To match other upgraded aero components like side skirts, canards, or front lips
For enthusiasts looking to elevate the Supra’s stance while maintaining OEM fitment quality, this diffuser is an ideal choice.
This diffuser is not a universal accessory—it is precision-molded specifically for the 2019–2025 GR Supra platform.
Perfect contour alignment
No awkward gaps or spacing
Factory-style mounting compatibility
OEM-like aesthetic integration
Many aftermarket diffusers require heavy trimming or drilling, but this Supra-specific design provides direct-fitment convenience, making it suitable for both DIY installers and professional body shops.

About
The Supra’s underbody is designed for efficient airflow, but the OEM configuration prioritizes daily drivability over extreme aero performance. The Type A90/A91 Rear Diffuser Bumper Lip enhances this with:
The multi-fin design helps guide airflow as it exits from underneath the vehicle, reducing turbulence and stabilizing high-speed movement.
By improving the underbody airflow path, the diffuser minimizes lift and increases traction stability.
The diffuser frames the lower exhaust area, making aftermarket titanium, carbon, or stainless exhaust systems visually stand out.
While downforce gains can vary depending on vehicle setup, the diffuser provides measurable aerodynamic refinement when paired with additional aero components such as a front lip, undertray, or wing.
