Be that as it may, the JRZ product as it is built is NOT a fragile or maintenance intensive part. We have sold a ton of RS doubles over the years and we as of the end of last year just started to see a very few sets trickle in for service - most were 5 years or so old of frequent use. I had a set of RS on my street car for 20k miles before they were sold and are still in service for track use without a rebuild. RS1 should be expected to live similarly long lives.
