Diameter of 944 turbo front hub

[Bugnutz]

Hello all-

Can anyone supply me with the outside diameter of the Porsche 944 turbo front hub? These are the ones where the brake rotor 'hat section' fits on from the outside in normal fashion, as opposed to the NA type hub where the rotor was mounted inboard.

I am thinking of using my 5x130 studded Ghia rotors as front hubs for bigger brakes by cutting off the original disc, leaving me with a sturdy cast iron hub with no bearing hassles. Besides, I already have them.

The ghia hub section diameter measures approximately 170mm.

Any help here would be greatly appreciated!

Regards, Mark (Bugnutz).
