keep a look out on flee-bay for the spindles, I got mine for $20 and the hubs w/rotors for $30
Also for tie-rods, I just bought speedy's and they are perfect length. I noticed that no one mentioned this but the stock yfz450 tie-rods will be too short when you run the yfz spindles.
The only thing I haven't upgraded yet are the front calipers, but that will come soon. Yes stockers fit on the yfz450 spindles, you just need 1/4" longer mounting bolts.
