Sportstop Cryo Sport Dril

This is a StopTech / PowerSlot replacement brake rotor specifically designed for the 2002-2005 Subaru WRX. It is sold individually and is a rear, left-hand (driver's side) drilled and cryo-treated rotor. The Power Slot's exclusive Vac-U-Slots are machined into the rotor to help evacuate gasses and dust, shed heat, and maintain a clean brake pad surface. In wet conditions, these slots also help to push water off the braking surface for improved stopping power. The rotor features Power Alloy metallurgy and directional cooling vanes to enhance high-temperature performance. For corrosion resistance, the hat, edges, and internal vanes are finished with a durable black e-coat, while the braking surfaces are left in a bare iron finish to optimize brake pad bed-in. The deep cryogenic treatment is a one-time process that permanently improves the performance and service life of the metal, providing an extra level of protection against warping.
