I have the outboard braked rear. From a performance/ride standpoint on the street, there's not much of a difference. But, from a maintenance point of view, repairs and maintenance are much easier. That's not just the brake pads either, if you have to change out a stub axle on the differential you can do it in a half hour --
without having to drop the rear or pull the hub. Popping the half shafts out is quick and straight forward, as is rotor replacement. Let's say you wanted to replace the pads, rotors, and repack the inner & outer wheel bearings. On the ERA outboard braked rear that's an afternoon's job, moving at a leisurely pace and, again, you don't have to drop the rear to do it (although you do have to pull the hub). On an XKE with the inboard brakes, it's a nightmare. On an ERA with the Jag rear, it's less of a bad day, but still a significant PITA. Changing out U-Joints is another example. Go with the outboard braked rear, you'll be glad you did.
