Here's a twist.
I've used in the past the rear brake set up from a crown vic.
I've never hooked up the emergency brakes, but it's like the explorer style. Where the emergency brake is an internal drum design.

The advantage is you can use the stock fox length 5 lug axles that you rob from the rangers.

New rotors are pretty cheap at the parts store. Starting out at about $28 each. Pretty sure they are larger than 11 inches in diameter.

The disadvantage is a little more un-sprung weight. and the emergency brake is an unknown. I'm sure it can be done, but I've never tried.

I have to pick up new disks this weekend so I might be able to measure them if it's a factor.

I ran this set up on a '84 mustang with 17x9's and 275s for a year or two.
