Gotta think about the cool factor with the massive brakes too 
I worked for DM Division of GM and semi-metallic linings become the std replacement pads after warranties expire as they are the better brake with the ceramics better for less noise and dust. We've got a good design. Don't mess with it.Astrafari front brake rotors and J55 calipers with D513 or D614 pads is what GM should've done.
I get why GM did not do it, but ...
Anyway
The Astrafari-J55 upgrade would likely outperform any Summit kit that does not improve on the OE B- car's (lack of) rotor mass or thermal capacity - and for far less money.
Those of us who are still lucky enough to own Caprices RoadMasters or Fleetwoods would be clever to expand our definition of OE to profit from sherlock9c1's efforts.
after about 1000 miles at most.The black on the wear surface goes away.
Ya, I saw an EBC video about the procedure plus they say there's very clear instructions in the brake box for how to do it. I will definitely follow them. Thanks!after about 1000 miles at most.
With EBC rotors and pads, using their specific break-in (brake-in?) procedure is important.
