What pads are you running? I was just looking into resin pistons and shimano apparently doesn't rate their calipers with resin pistons for sintered pads.

First set, came with the caliper, the next set is a COOMA SPORT semi-metalic set from Aliexpress:   https://www.aliexpress.us/item/3256803539662365.html?

FYI, I am running a 203 rotor with the Frog Wake brake.

can somebody rate the difference between ultegra 12speed calipers and Zrace?

Hmmm.   I wonder if these might be good calipers...
