||I had terrible squeaking after my 350z rotor and relocation kit install. After grinding down the pads to remove the overhang and doing another bedding procedure it persisted. I also wasn't satisfied with the lack of pad coverage on the rotor. It was so bad I almost went back to stock. After some digging, I found that you can buy these that fit perfectly in the front calipers and eliminate the overhang and reduce the missed rotor coverage by about 50%.
Squeak gone, pad overhang gone, minimized lost surface area and no other issues since switching. I don't do much other than street driving so no experience with fade, but thought this might be helpful.
