Cryogenic treatment

We didn't do another set, unfortunately, to prove it out fully. Most teams went with Hewland's recommended 2k mile lifespan. Early on, you might only get 1K miles. They had to be set up perfectly in the middle of the spec range and then broken in just so. That would get you to 2k miles. Because of the amount of time it took to install another set, nobody really wanted to take a chance on pushing them.

The set I have (the cryo'ed ones) started in a racecar, then into the test car, back to the racecars, and back to the test car before we called 'time'. I don't recall ever trying cryo on other parts but dog rings would have been interesting test subjects.
was the replacement cost of a complete unit if you did run them too long excessive (within the realms of "it's racing, of course it's excessive") compared to the servicing every 2k cost.
