EBC BSD front rotors for 2003–2004 Subaru Impreza WRX/STI use a V-pattern slot that improves heat dispersion and helps pads run cooler versus standard OE rotors. The BSD design adds performance and style with an ultra‑quiet slot configuration intended to reduce noise while enhancing thermal control. These vented front rotors are aimed at vehicles seeking improved sustained braking and a more aggressive braking response.
