just so you know your theory is out the window with 60's 70's and 80's. technology. thats just old school.
back brakes used to out last the fronts by a 100,000 miles. not any more, the backs wear just as fast as the fronts. "A LOT" of back brake has been added to newer cars.
hell in my last truck the backs wore out before the fronts every time. 03 gmc 2500HD and that goes for the factory pads it came with too.
my regal has the f body up grade with stock rear calipers, they all wear at the same rate still. just changed pads a few months back. all worn evenly.
so will better back brakes be better? hell yes they will.
the bigger question is, is it really worth it? your wallet can decide for you. everyone who has done it seems to love it.
only problem is you need larger wheels, one more cost to add. then the parts are not really cheap, and then theres the fab work needed for the brackets in this case.
