Those are the MRR Groundforce GF9 wheels in a 19x8.5/9.5 custom offset fitment

Tires are the factory Pirelli P Zerop 255/275 tires from the GT PP and springs are the Eibach Pro Kit

why are 19 inch wheels in short supply and more expensive when they are OEM on the Mustang and the preferred size for the GT350?

It dependa on the wheel to be honest, also keep in mind the gt pp calipers are so tall they require a wheel in 19" that had enough inner barrel clearance for the caliper. Also aince the s550 is the first platform to use these massive 6 pots the wheel industry is adjusting to the demands of the s550 owners, hence why mrr and i have designed the wheels we will be releasing shortly since it caters to what you guys desire.

6 piston yes but not the same. Bigger pots with larger overall caliper size on s550 is what I've been told.

Interesting. Have not heard that before but this seems to have some validity.

If you hear testing of the car around the track, no one complains about the brakes at all. Even after repeated laps such as in the Terry Fair video. I say this as the GT500 had repeated drivers complain about the brakes on the 13-14 GT500 and how after one lap they would go away. No clue if the pad compound changed but, figured I would share my viewpoint on this.
