SPORTSTOP CRYO ROTOR

StopTech / PowerSlot replacement rotors for the 2005, 2006 and 2007 Subaru STi. Sold individually, price is for one rotor. Some are slotted or drilled and fit specific to left or right sides. Cryo-treatment is available. 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, Vac-U-Slots help push water off the braking surface for better stopping power. Special Power Alloy metallurgy and directional cooling vanes improve high temperature performance. PowerSlot rotors are finished in a durable black e-coat on the hat, edges and internal vanes to prevent corrosion. The braking surfaces are left in a bare iron finish to improve brake pad bed-in. Deep cryogenic treatment is a one-time process that permanently improves the performance and service life of metals, redistributing residual stress in the rotor to protect against warping.
