Recommend a rear disc kit

I'm at the point of fed up with my current rear disc set-up, so I need to make a change over the coming winter. I currently have Wilwoods on the front, which work great, but the rear set is a functional but annoying bit of backyard engineering. Because I have 80's Camaro front calipers on Grand Cherokee rear rotors, I struggle with the pistons being extended a bit too far out of the bore. This gives the appearance of a lot more drag than should be there. After ten passes, there is a huge amount of pad dust inside my rear wheels, and the pads themselves show a remarkable amount of wear for the 300 or so actual miles they have on them.
Now, I hope the picture shows it properly, but the caliper bracket is a water jetted piece that is welded to the housing. I can pull the housing, zip-disc the bracket off, and completely smooth the housing if need be. Does anyone have any recommendations for replacing this set-up on my 9-inch?

Nudder pic.

One more.

I can say you have some pretty small pads for the
amount to force your applying... thats why your seeing
the big wear... if you had greater surface area you
wont see the wear and get better braking
EDIT
With big slicks and skinny fronts you need to apply
more braking on the rears so you need bigger brakes...
the car weight will also dictate how big you need...
I would rather have to big than to small(you can
always press lighter)... so give us a bit more info
on the car

I have seen posts, that people like the aerospace components brakes, because of the Little to no drag. so thats what I have on all 4 corners...

I like the Strange disc on the rear because of the one piece rotors.

Pic of car is attached. 3100 lbs with me in it, 115-120 trap speeds. Now, I have tried to find a comparison drawing of the 02-08 Ram 1500 rear rotor to see if that might be a way to at least solve the piston extension problem, as they are considerably thicker. These particular (98-2005 Grand Cherokee)rotors came out of scrap bin at the brake shop as they were too worn for further road use, but for a modest drag car they're just fine. Or so I thought. I simply bored out the hat a little bit to fit over the axle ends, and re-drilled the bolt pattern. Given that my brake geometry is a little bit off, I could easily go about 1/2" bigger dia. from these. It's easy enough to machine the OD of rotors that are too big to fit inside my existing calipers/brackets. That would also give me the opportunity to tailor the rotor diameter to the actual nominal dia. of the caliper/bracket geometry. But, I'm also amenable to the notion of a rear disc set-up that simply bolts to the housing via a collar, if such exists.
As it stands, the car slows down very nicely. I just think that with that much brake dust being generated, I might be losing ET/MPH due to high residual drag. I could be wrong about that. Not a new phenomenon. Just ask my wife/kids.

I have tsm rear brakes, love them.

If you use the strange setup on an a-body your gonna have to get a 1/4 inch bearing shim so that the brake rotors will center up to the calipers.
