Description

The AMS Performance Anti-Buffeting Kit for the 2020+ Toyota GR Supra A90 eliminates one of the most annoying quirks of the GR Supra: the loud, low-frequency wind buffeting that occurs when driving with the windows partially down. This deep, pulsing pressure wave is common on the Supra due to its side-window geometry and door-mirror aerodynamics — and AMS engineered a simple, elegant solution that restores comfort without compromising style.

Using CFD analysis and real-world testing, AMS developed a pair of aerodynamic deflectors that redirect airflow slightly outward, preventing the pressure oscillations that cause buffeting inside the cabin. The result is a quieter, smoother driving experience, allowing you to enjoy fresh air without the headache-inducing resonance the Supra is known for.

Each deflector is molded from high-quality, UV-stable injection-formed plastic designed to withstand sunlight, heat, and weather without warping or fading. The subtle matte finish blends seamlessly with the Supra’s trim, making the pieces appear factory-installed rather than aftermarket. The fitment is precise, and once mounted, the deflectors stay secure even at highway speeds.

Installation requires no drilling or permanent modification. The kit attaches cleanly using automotive-grade adhesive backing that bonds firmly to the door frame for long-term durability. The entire process takes only a few minutes per side and can be easily reversed if needed.

This upgrade is one of the most popular comfort-focused additions for the A90 Supra, especially for owners who frequently drive with the windows down or enjoy spirited backroad driving where cabin comfort matters.
