Go to summit and by the brake kit that includes the 3 or 4 piston calipers, drilled and slotted rotors, pads and stainless steel braided brake lines.
Or you can do what i did and go down to advance auto parts and buy the bendix drilled and slotted rotors and ceramic pads from them. Rotors costs me 190 total and the life time ceramic pads costs 30.
But since you are running 22" then i would highly recommend buying the baer brake kit which included bigger rotors and better calipers along with the stainless steel braided brake lines. Last time i checked you could pick this up for about $1500. It will dramaticly reduce your braking distance.
