Ed, The 11" brakes use the Granada rotor that is a 5 lug 4.5" pattern. The hub is part of the rotor. The caliper is a mid size GM from a Camaro. There is also a bracket to mount the calipers to the spindle. You can buy the whole package in kit form for around $275. The calipers use a different brake line so you also need 2 of those. The granada setup is 11" so you will have better braking vs. the 9". The difference will be in the fading. The 9" will heat up faster than the 11" so it will be noticable in hard braking. The setup is off the shelf parts except for the brackets which can be purchased separate for about $80.
