Stoptech fitment

This is likely a shot in the dark but I am curious what difference, if any, there is between the Stoptech BBK for an e9X and one for the F80. Would the mounting brackets be the only difference or is it likely the calipers and rotor hats are different too?

If it's just the brackets does anyone know if I can get just the brackets from Stoptech?

Found some information for anyone that is interested. The F80 kits come with 380x32mm disc front and rear. The front disc is a wide annulus version. The front caliper is an ST60 and the rear is an ST41.

The ST41 appears to be smaller than the ST40 that comes with the E9x kits which I find odd since it is paired with a much larger disc.

Waiting to hear back from Stoptech on if I can just buy the mounting brackets and new disc.
