Deep cryogenic tempering is a one-time process that permanently and dramatically improves the performance and useful life of metals. Cryogenic tempering isn't a completely new idea. The freezing of metal in an effort to increase its durability and strength has been practiced for some thirty years within various industries. The advent of "deep cryogenics" opens new possibilities, in the case of brake rotors and brake drums.

The cryogenic system consists of a special enclosure unit, equipped with state of the art thermal sensors, a computer system utilizing highly specialized software and dewars of liquid nitrogen. The process it self takes approximately 72 hours to complete. Metal parts are slowly reduced beyond 300 degrees below zero, where they remain for hours, at which point the enclosure is raised back to room temperature at the same rate it was reduced and then heat-tempered as the final step.
Although not apparent to the naked eye, the improvements to the metal are significant. Deep cryogenic tempering creates dramatic increases in abrasive wear resistance and durability. The increases in tensile strength, toughness and stability couple with the release of internal residual stresses.

The end results are brakes with unsurpassed rotor and pad life, decreased stopping distance, and the elimination of brake fade and rotor warpage.
