All I have is the bracket kit. You would need to source your own rotors, bearings, calipers, and hoses. But, I'll cut you a better deal on it than you can find anywhere else, $150. Add calipers and pads $400, and rotors and bearings for $150 and you have major stopping power with a choice of pad compounds.
BTW, Wilwood does offer a 12.12" kit. This is the biggest you can fit in to some 15" wheels. But they are a bit more expensive than their 10.5" kits.
