Yes, the PP rotors are 380mm. The base GT rotors are 352mm.
You can check here on the Steeda site for example:

Yes, the rear brakes (rotors and calipers) are all the same on the base, PP1, and PP2, even Mach 1. Only the Shelbys have the 4 piston brembos in the rear.
Selling the following items:
1. Takeoff PP1 Brembo calipers + PP1 rotors + Pads. Bought these on ebay as a takeoff from a 2021 model year. They look brand new! Asking $600. Will throw in the dust shields from a PP1.
2. Master brake cylinder, brand new from a PP1. Asking $100.
3. ARP 1"...
Selling the following:
A set of SVE S350 Wheels, 19x10 +40 offset. Mounted with Bridgestone RE71R tires in 275/40R19 size. The tires still have quite a bit of life in them. Only used the tires on the track or autocross. Just recently flipped them side to side and balanced maybe 2...
Vorshlag website has the rates for the Bilsteins (see below). They're progressive springs, but the rates go fairly high on the front and seem to work pretty well for me on autocross, yet comfortable for a daily.
Bilstein PSS10 with Camber Plates for S550 Mustang - Vorshlag (vorshlag-store.com)
I would suggest to take a look at the Bilstein B16 coil overs as a good option for autocross and daily. I am no autocross expert, have less than 10 events under my belt, but I can’t complain about their behavior. There’s minimal dive or body roll on the stiffest settings and it’s quite...
Yes, there are special spacers for the rear and for the front. The front spacers are here:
Steeda 555 8254 Mustang Front Ride Height Spacer Kit (15-21)
The rears are here:
Steeda 555 8251 Mustang Billet Rear Spring Spacer 1/4" (15-21)
You'd need the 1/4" inch for the rear to increase the...
I don't have a "before" pic, but I've used the spacer on the front and the rear after my coil-over install. It's a 1:1 increase for the front I think and a 1:2 for the rear. So just eyeball approximately how much you want to increase the height and go from there to select the right height spacer.
A base 2019 GT would not come with those parts. Perhaps the California special does, but definitely not the base. I have the base as well and upgraded those parts.
Looks like you can buy the spacers and the washers from Steeda for $50 or try to source them from a Home Depot.

I'd recommend looking into Haggerty insurance if you have a different daily car/beater and put low miles on the Mustang. I'm 35 in SoCal paying about $70 a month. Haven't used them yet, but they seem like a big/reliable company.
