Rx-8 stationary and "multy window bearing" or racing beat type-II gear and 3-window?

I'm pretty sure the RX8 offers a lot of the same advantages of the Racing Beat unit. RB's hardened ones were the hot set-up until the factory started doing basically the same thing. I just ordered the RX8 units for my new build.

I don't have the answers, but what parts are you starting with? And how high do you want to rev?

previously everyone wanted fd bearings, are rx-8 the same but better?
do they fit in the same holes? how about price comparisons?

The FD are probably the cheapest I have found because there are plenty of these motors floating around. Nice bearings because it has holes all around the inside. Great factory design.

I am not 110% but I beleive the RB 3 window bearings also have more clearance, allowing for higher rpm's. Not sure about the renesis bearings, will have to look at one tomorow. I know the renesis are like the REW bearings in which they are screwed in not the slot to line up(or whatever its actually called), like all previous years.

I dont like the idea of loose clearance bearings, at high rpms it may allow E shaft flex and could allow the rotors to touch housings, might be trouble, of course if you could have a stiffer E shaft you would not need loose clearances,, loose clearance bearings anyplace are just a band aid for poor engineering.

The shaft is going to flex, the extra clearance allows it to not wipe out the bearing. We taper the E shaft journal surface for the same reason. Please PM me if you fix the flex problem for under $3000! Technically your right about the band aid but its what you have to do.
