Yo CKCOBRA,
You may wish to try Baer. They have a complete setup that goes right on the MII spindle. I have their track setup with the big PBR calipers (same as Mustang Cobra, Corvette etc) and ~13" rotors and am very happy with it.
It's been on the track for several hours and never a hint of fade.
It came with hubs, bearings, grease, rotors & hats, brackets and everything needed for the conversion.
They're at
Baer brakes
You'll need to be careful about wheels, as it will only work with 17" or larger. Also, it narrows the front track something like 3/4" total (3/8" per side) if memory serves

which will change your required wheel offset by the same amount.
Regards,
Tom
