Product Description

The SHW PRX39873 brake rotor is a high-quality rear replacement rotor designed to meet or exceed the original equipment standards for select Porsche 718 Boxster and Cayman models from 2017 through 2020 when equipped without ceramic brake options. Manufactured from premium high-carbon alloy, this rotor improves heat dissipation and delivers consistent performance under repeated braking events, whether on city roads or spirited drives.

Unlike plain rotors, the PRX39873 features drilled and ventilated surfaces that aid in cooling and help reduce brake fade during aggressive applications. Precision machining ensures a smooth contact surface for brake pads, resulting in stable pedal feel and reliable stopping power. Its direct-fit design makes installation straightforward, replacing the OE part number 98735240101, and it offers long-lasting service life thanks to corrosion-resistant coatings and German-engineered manufacturing quality.
