My car (Hawk 289) also has the MGB front "splinned" hub. As I have not built the car myself the infos I have are limited. But I can say that initially it was rigged with the MG's rotor/calipers and its been converted with 1990 rear corvettes rotors ,12 inches or could be 11 1/2 not sure and the calipers are PBR that are on mustang GT. A possibly difference with your set-up is that I have splinned hubs same as MGs...for the wire wheels. I can say that these have over 2000 miles on and works fine. Looking at it I figure that all it needed was a special machined bracket to attach the caliper and the rotors to be drilled to fit on the hub base. Anyway if it could help you I could put you in contact with the person who built it. Just e-mail me for this if that is what you want.

regards.
