Performance caliper - same across 2017-2021?

I noticed the MPP caliper upgrade for a stealth, is there concern or correction for bias for the front calipers as I assume they may need a different pressure? Is it common to replace solely front rotors, pads and calipers and leave the rear stock non PUP?

I did see the parking brake issue with non PUP to PUP.

All Performance calipers are the same. A "stealth" performance is just a dual motor with a software change (P-). A Performance WITH the PUP (including the brakes) is a P+. There is no Performance with a 0-60 in 2.9 - that guy is trying to take you for a ride lol. Both P+ and P- have Track Mode.
Slight off top, but do you know by chance if 17" will fit on performance or non-performance given low enough offset?

The MPP front BBK for the non-Performance brakes is appropriately sized for the correct bias. You definitely will need upgraded pads on the rear.

Absolutely no way 17" wheels will clear Performance. 18's are hit or miss. A 17" wheel with good brake clearance should clear the base rear calipers.
