Power Slot Cryo Slotted Rotors: When you need something tougher than a Power Slot rotor, but you're not quite ready for a big brake kit, try our new Power Slot Cryo rotors. Power Slot has teamed up with Frozen Rotors to offer cryogenic treatment on the Power Slot rotor line.
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 -300F and then slowly returned to room temperature and heat-cycled as the final step. Although not apparent to the naked eye, the improvements to the rotor are significant. The cryogenic treatment process redistributes residual stress in the rotor giving it an extra level of protection against warping.
Just as standard Power Slot Slotted Rotors, Cryo Rotors start with the following features:
Power Alloy castings (on select applications)
Engineered Performance Rotor
Superior resistance to cracking due to thermal stress
Increased molybdenum (higher carbon)content that extends reliability, service life and helps reduce NVH noise issues
Rotor material is a direct descendant of the patented AeroRotor from StopTech
Introducing directional curve vane design (on select applications)
Improved vane design or OE equivalent on all rotors
Center split castings
New short slot design runs perpendicular to the vane to preserve rotor strength.
Direct OE Replacement
Improved wet weather response
Increased initial bite
Double disc ground for a consistent friction surface and Improved pad bed-in
Black E-Coated non-friction surfaces on Power Alloy rotors
