Steel or pccb? I know there is a difference in the pccb caliper from .1 to .2 the .2 pccb caliper is just a smidge larger tall towards the wheel barrels. Sorry don’t have part number info but I bet you dealer parts guy could look that up on PET quick.

I'm looking for what the difference in inner workings of the caliper is

The ceramic pucks on the pistons are now a different shape (curves on the edges on the .2) presumably to make them more robust against edge cracking failures. I’ve yet to hear about cracked pucks on a .2.
