I picked up a set of S550 Performance Package front brakes late last year and am finally getting around to test-fitting them. While the 6-piston setup from the '13/'14 GT500 seems to have some tech, the S550 PP one does not. If this has been covered in another thread, please LMK and I can move the content there.
I took measurements on the S550 rotor using a dial caliper for all but the diameter, and used Centric data from Rock Auto on the GT500 one. I will likely buy a GT500 rotor to confirm measurements and do a physical test-fit.
Biggest differences:
Test-fit on S197 spindle with full S550 setup:
Creating offset using spacers between the spindle and rotor, to simulate estimated GT500 offset:
This is close but I still need the GT500 rotor to confirm:

Biggest differences:
- The GT500 rotor is 1.26" thick versus the S500 one being 1.34"
- The effective hat offset for the GT500 rotor is 0.232"* versus the S550 at 0.868"
