Agreed. Nice to know on the shape of caliper = pedal feel.
GMPP is definitely a two piece. I am almost certain I have seen it taken apart on someone's sale thread once. I'd also be interested in purchasing these calipers. Just need a wheel that clears them.
I did some part number searching and came up with this for the list of required parts for the PPV upgrade. I am a little taken by the rotor price so I am a bit skeptical of the PN listed. The PN for the 16" GMPP rotors listed earlier are over 3x the price of these.
There is also some chatter on other forums that the dealerships are not selling these parts without a VIN as GM had to issue a stop order on PPV orders last year due to parts shortages. Its a good value at online prices but MSRP is right there with the GMPP or Wilwood kits.
@Drspencer, have you installed yours yet?
If so... what did you do for splash shields? Get the GM matching ones or trim the existing?
If not... can you measure the piston diameters on the caliper?
Also... what type of coating is on the caliper, if any? It looks too dark for raw aluminum from the pics.
@Drspencer, have you installed yours yet? Nope, after discovering my wheels won't clear, I went on the hunt for a set that will.
If so... what did you do for splash shields? Get the GM matching ones or trim the existing? I forgot about splash shield. I forgot about splash shields as well as the hardware kit so, I'll probably grab those while I'm waiting to come across some wheels
If not... can you measure the piston diameters on the caliper? Yep, they're in the garage so I'll take a caliper to the pistons and see what they measure.

It looks like some generic anti corrosion adonizing. Low cost way to keep the corrosion down in salty winter climates.
There's a guy on the Facebook group with them installed. He's using the GMC 20" wheels from 2019.
