Bruce, there are a number of posts discussing the failure rate of the jaguar.
For instance, here:
http://www.chiefdelphi.com/forums/sh...fai lure+rate
In that post they discuss a total of 88 jags to date. When you consider that close to 4000 jags were shipped to teams just in the kit of parts, I'd wager the failure rate including all jags sold is well below 1%. I think I would argue with your "extremely high" statement.
There will be a new black jaguar that has been discussed repeatedly both on this forum and the usfirst.org official beta forums that has some modifications to improve the durability further.
