ABS Power Brake in Orange, CA can provide a complete kit with 6 lug rotors that do not use a separate hub.
I have installed several of their kits and they have worked well. Many of the aftermarket kits do not clear original
wheels. Be sure that whatever kit you get that you designate what wheels you are using.
