Sorry guys -- we just realized that the car versions of the 1717 were incorrectly listed as having a 5mm shaft.

About the 45000 RPM limit -- at 45000 RPM the magnets have a centripetal force of over 1500lbs/sq in on them (about 30,000 Gs -- seriously...) -- that's about the physical limit of the kevlar reinforced magnet structure. To go any higher, we would need to get a stronger material than Neo/iron/boron magnets. :(

We just don't know (yet) how to hold the structure together at above 30,000 Gs.
