StopTech 05-17 Subaru Impreza WRX/STi SportStop Cryo Slotted & Drilled Front Right Rotor

StopTech / PowerSlot replacement rotors for the 2008-2017 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. Excessive heat can cause resins in your brake pad to vaporize or "outgas." As the brake pad wears, the used friction material turns into a fine dust. This boundary layer of heat, gas and dust builds up between the pad and rotor surfaces and inhibits performance. Power Slot's slotted brake rotors make a big difference. 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. And in wet, raining conditions, Vac-U-Slot helps push water off the braking surface for better stopping power. For most late model truck and SUV applications and select sports cars, a special Power Alloy metallurgy and directional cooling vanes are used to 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 from brake rotors and engine parts, to machine tools and gear sets. Using a proprietary computer-controlled process, the metal is cooled gradually to -300°F and then slowly returned to room temperature and heat-cycled as the final step. The cryogenic treatment process redistributes residual stress in the rotor giving it an extra level of protection against warping.
