ST Trackparts AeroDiscs are engineered specifically for track applications to optimize aerodynamic efficiency by enhancing airflow around the rear wheels and minimizing drag. This targeted design contributes to improved vehicle stability and performance under high-speed conditions.

Manufactured with precision, the discs are CNC-machined from durable ABS material, ensuring consistent quality and resilience. The mounting brackets are constructed from carbon-reinforced plastic, providing superior heat resistance essential for rigorous track use.

The AeroDiscs feature a fully Plug & Play installation process, including all necessary hardware for immediate fitting. Additionally, the package includes protective PPF stickers to safeguard the wheel surfaces. The discs attach securely to the wheel spokes, and the open bolt holes allow for straightforward installation or removal of wheels without additional disassembly.
