Sorta... after my first track event, where I was able to get the brakes hot enough to experience fade, the backing plates fell right out the next time I took the pads out. I don't think you can get them separately - only with OEM replacement pads.
As for the fitment, the Hawk rep said the HP+ pads should not be used with OEM backing plates, although I'm still not totally convinced he's not just speaking of the "norm", where the backing plates typically aren't part of the fitment surface and are just for noise cancellation.
That said, I'll be trying the HP+ with TiAl shims and NO OEM backing plate in Mid-Ohio this weekend and see if anything falls apart.
