I'm not intimately familiar with Dr Diff rear rotors, but are they thicker where they mount to the axle than the drums you took off that 8 3/4 ?

If so, how much? If so, they makes you rear a little wider too.



Not by much. The outside face of the rotor I have in the rear sits just below flush on the center register on the axle, so yes it is thicker than the stock drum.

The front kit he has is the same as mine. It is like taking a Cordoba hub and cutting the rotor off. Then add the rotor thickness. So it ends up a bit wider than the Cordoba brakes. I think Cass designed it to work with the late model Mustang wheel offsets. To get the same size front and rear and get them to sit right, like a 17x8 wheel for example, you would probably have to go with a small 1/2" spacer on the rear.

I would just ask Cass (Dr Diff), he sells the kits and knows what works.
