On a related note, the Dr Diff 10.75" rear disc setup ... which allows the factory and most preferred tapered axle bearings (and using whatever Mustang calipers)... does NOT allow clearance of the factory sway bar end links... therefore... you have to change the sway bar to an under-axle-design. That was a big surprise... I discovered it the hard way.. Cass confirmed (I wish it was indicated in his description of the setup). I had to remove my custom 1" factory-shaped upper sway bar... purchased a Helwig 7/8" (three point adjustable) under axle sway bar... a bit of a hassle to install ... but satisfying when all done (plus the purchase price.. fortunately, Summit had it in-stock and I recvd it in a cpl days).

Using the Cordoba 11.75" front rotors and factory calipers, along with the Dr Diff 10.75" rear discs, I cannot lockup the rears... only the fronts under severe braking... so far, relatively satisfied. I installed an adjustable proportioning valve... I leave it completely open... no bias needed towards front or rear... I could've probably not even bothered with that install.
