I went with the larger front brakes combined with the ERA rear suspension to keep things balanced. I'm very pleased with the results. Was thinking about going with the standard front brakes with the upgraded rear but decided against it. There is a reason why the upgraded fronts are recommended. In any situation the front brakes are working harder than the rears.
Went with the upgraded rear for two reasons. I used to own an XKE and even with a lift changing the rear pads was a pain not to mention any work necessary on the calipers themselves.
The second reason was to eliminate the wheel hop that could happen with the standard rear end. While not a problem with everyday driving, even somewhat spirited, it can show up when leaned on. The aftermarked hop prevention linkages appear to take care of the problem but I prefer not to have it in the first place.
I'd recommend bouncing your ideas off Bob P once you have done all your research. He can save you a lot of heartburn down the road.
