StopTech Sport Rotors are also available with an optional cryogenic treatment. Although cryogenic treatment is invisible to the naked eye, many fleet customers are sold on its ability to extend the service life of the brake rotor. Deep cryogenic treatment is a one-time process that permanently improves the performance and wear characteristics of metal components, from brake rotors and engine parts to machine tools and gear sets. All new StopTech Sport Rotors may be ordered with cryogenic treatment for an additional fee.

What started as a Crew Chief's hidden racing trick (stolen from 24 hour endurance racing teams in the 80s and 90s), to have brake rotors and hubs last longer during a race, the cryo treatment of brake rotors and other metal parts subjected to heat fatigue is a proven method to make them last longer and it has turned into an industry unto its own called Cryogenics and it is big business to this day.
Here's how the Cryo-Treated-Rotors are made by Centric-StopTech:
Cryogenic treatment is a one-time stress-relief process that involves both cold and heat cycling of the brake rotor. Using a proprietary computer-controlled process over a 24-hour period, the cryo machine gradually cools the rotors down to -300 º F, then gradually brings them up to over +300º F, and finally back to room temperature. This conditioning of the rotor improves its service life, especially in fleet and emergency vehicle applications.
For drivers who need something even tougher than a standard StopTech® Sport rotor, but are not ready for a big brake kit, these StopTech cryogenically treated Cryo® rotors offer further racing durability.
Any new StopTech® or Centric Premium 1-piece replacement rotor can by cryogenically treated prior to shipment. Cryo treatment typically adds 5-7 business days for processing and typically it adds about $30 to $35 to the cost of a rotor.
