Spindle bearing spacer

"increases wheel spin by 1200%"

whaddya saying.....i'm gonna have a lack of traction....!

I don't doubt there is some benefit but i think its being overstated
it assumes that the support area machined into the stub at the back of the inner bearing isn't true to the support of the outer part of the outer bearing, which in our (and most other) case(s) is a big fat machined washer hence usuing a presicion spacer inbetween makes sure this is the case... MMmmm ok washer is backed by a threaded nut is it parralell with the plane of the inner bearing?

do you get your 1200% increase in spinny-ness due to this or the special seals??
