Remember: Banshee, Warrior, Raptor, Blaster(03+), Yfz('04), front brakes all fit on 03' Blaster spindles...
Also cheaper to buy banshee, warrior, raptor hubs/rotors for the 03 spindles....
Just search around, this swap can be done cheaply if you take the time to scope out ebay. I did the swap w/ Banshee front calipers, Warrior master cylinder w/ SS lines, Got 2 sets of banshee hubs, front spindles(off an 06), banshee rotors, etc... all for 91$... Just takes some time to find the deals, but they are on there.
