400ex hubs and spindles and yfz450 brakes. make sure you get the ones with dual piston calipers.

Will the 250r hubs and rotors work ?? I'm also using ex spindles on my roll design .. Or so I gotta buy the damn ex hubs too ...

I'm running 04/05 450r spindles hubs rotors and calibers and they've been great so far but I don't have alot of time on them yet.

Yes they will and 250r,400ex or 450 rotors will work as well.
