ST Trackparts AeroDiscs are engineered specifically for track applications to optimize airflow around the rear wheels, effectively reducing aerodynamic drag and enhancing vehicle performance.

Manufactured with precision, the discs are CNC-machined from durable ABS plastic, while the mounting brackets utilize carbon-reinforced plastic to ensure resilience against the elevated temperatures encountered during track use.

This product offers a fully Plug & Play installation, including all necessary hardware and protective PPF stickers to safeguard your wheels. The discs attach directly to the spokes, and the open bolt hole design facilitates straightforward wheel installation and removal without requiring disc detachment.
