SPORTSTOP CRYO ROTOR

StopTech / PowerSlot replacement rotor for the 2005, 2006 and 2007 Subaru STi. This is a rear left, drilled/slotted, and cryo-treated rotor. Power Slot's exclusive Vac-U-Slots are machined into the rotor and help evacuate gasses and dust, shed heat, and keep the brake pad surface clean. In wet conditions, the Vac-U-Slot helps push water off the braking surface for better stopping power. Power Alloy metallurgy and directional cooling vanes improve high temperature performance. Rotors are finished in a durable black e-coat on the hat, edges and internal vanes to prevent corrosion. Deep cryogenic treatment is a one-time process that permanently improves the performance and service life of metals from brake rotors and engine parts, to machine tools and gear sets. This process redistributes residual stress in the rotor giving it an extra level of protection against warping.
