I just ordered a pair of front eleven inch rotors for my seventy nine Zephyr. What do I need in terms of calipers and brackets? Will my existing ten inch calipers fit?
Any suggestions will be appreciated.

Assuming these 11" rotors are for a 87-93 5.0 mustang you will need 87-93 5.0 spindles and calipers.

1986 Mustang GT, 1989 Mustang GT convertible
1992 Mustang coupe, 4 swapped to 302
My plan is to leave the existing spindles (79 Zephyr) in place. What calipers fit these spindles using an eleven inch rotor? And, will I need a special bracket to make them fit?
Pretty sure you're stuck with the stock 10" rotors/calipers unless you change spindles as mentioned above.
The old spindle has a different taper (I think) than the 87+ V8 spindle, so the 11" rotor prob wont even fit the old spindle. Just getting a bigger rotor doesn't accomplish much.

You're going to need 15" wheels. The caliper for an 11" rotor binds against a 14" wheel. Been there, done that.
Ok, got it. In order to make use of my eleven inch rotors I need to buy 87-93 spindles and calipers.
Thanks!
1987-88 Thunderbird TurboCoupe spindles will also work. They are the same as 1987-93 Mustang 5.0L spindles.

You will also need brake hoses, and banjo bolts and washers, for those 1987-93 Mustang 5.0L calipers. Your old hoses will not work. You may or may not have to file out the brake hose bracket on the frame.
If your existing struts are not "universal" for 1979-93, i.e. the upper mounting holes are not slotted, then you will also need a set of struts specifically for 1987-93 Mustang 5.0L or a set of "universal" struts that will also come with spacers, with you will need to use. OR you can slot your existing struts mounting brackets and use four 1/8" washers per struts

I know the dust has settled on this thread for a while. The answers above are accurate and widely accepted yet not entirely the only answer.
I believe you could also use an 82-83 Continental or 84-86 SVO spindle with a Maximum Motorsports balljoint shim and an SN95 balljoint.
The advantage of this part over the 87-93 V8 spindle is that it also improves the steering Ackerman.
Carry on with the 4 lug 87-93 rotors. Use mustang/tbird 60MM calipers. The 75’s used by misc other cars like the SVO are designed for use with a different rear brake setup and going to 75’s without the other changes hurts braking performance vastly
I ended up getting a pair of 89 spindles, 5 lug rotors/hubs and calipers off of a Saleen. The spindles cleaned up great, the rotors need to be replaced and I plan on rebuilding the calipers.
