Description
Aero Package 1 is Group A’s complete front aerodynamic package for the Toyota GR Supra (A90), pairing our pre-preg dry carbon front lip with a matching undertray. Developed as a single system, it increases front downforce, manages airflow beneath the nose, and delivers a motorsport-inspired appearance. It is the recommended foundation for any A90 aero build.
- Includes: dry carbon front lip and dry carbon undertray
- Pre-preg dry carbon fiber construction for high stiffness and low weight
- UV-resistant high-gloss clear coat
Fitment: Toyota GR Supra A90/A91 (2019–present). Call (626) 808-4168 for fitment confirmation and to bundle with other A90 parts.
Front Downforce: CFD Results
Downforce is the vertical load created by airflow pressing the vehicle onto the road. Additional front downforce increases front-tire grip, sharpens turn-in response, and improves high-speed stability.
Test Methodology
- Vehicle model: 3D scan of a production Toyota GR Supra (A90).
- Test speed: 100 mph, with a moving ground plane to replicate on-road conditions.
- Baseline comparison: each configuration is simulated with and without Group A components. Published figures represent only the net change from our parts.
- Ride height: lowered configurations are compared against an unmodified vehicle at the same lowered ride height.
Results
| Configuration | Ride height | Added front downforce @ 100 mph |
|---|---|---|
| Front lip + undertray | Stock | +190 lb |
| Front lip + undertray | Lowered ≈ 1.3 in | +255 lb |
| Front lip + undertray | Lowered ≈ 1.7 in | In progress |
Results from our latest high-detail CFD study. An earlier, simplified study showed lower figures; we have updated this page as our testing improved. All front lip figures were obtained with the optional front splitter endplates installed.
Why Lowered Results Are Higher
- Ground proximity: with the lip closer to the road, airflow beneath the nose accelerates from approximately 90 mph (unmodified bumper, lowered) to approximately 128 mph. This higher-velocity flow reduces pressure under the lip and generates downforce. On an unmodified lowered A90, the slower air beneath the nose produces front lift instead.
- Same detailed model: both results use the same high-detail CFD model of the car, so the stock-height and lowered figures can be compared directly.
Summary: in our latest high-detail CFD study, Aero Package 1 adds approximately +190 lb of front downforce at 100 mph at stock ride height, and +255 lb on a lowered A90.
CFD-Tested Downforce, Not Just a Load Rating
A structural load rating tells you how much weight a part can hold. It does not tell you how much downforce the part creates while driving. The downforce figures on this page are estimates from Group A CFD simulation at 100 mph, so you can see what the part is designed to do at speed.
Airflow Visualization
Recommended pairing: combine with the Group A Gear 7 GT wing. The front lip adds front grip while the wing adds rear downforce, maintaining aerodynamic balance and high-speed stability.
