Product Description

The Hawk Performance HB664B.634 is a set of HPS 5.0 compound rear brake pads built specifically for the 2005-2012 Porsche Boxster (987) and 2005-2013 Porsche Cayman (987C), both with the 2.9L-3.4L H6 engine. The Ferro-Carbon HPS 5.0 formula delivers aggressive torque with smooth, predictable control, providing a noticeable step up in stopping power over stock rear pads.

Engineered for high deceleration rates with consistent brake release characteristics, this compound also offers strong rotor and pad wear life for long-term durability. It's a direct OEM-fit replacement requiring no drilling or modification, making installation straightforward. As with all Hawk Performance compounds, it's designed for use with iron/metal rotors and is not compatible with carbon ceramic rotors - Boxster/Cayman models equipped with PCCB (yellow calipers) should avoid this or any Hawk pad compound.
