It's the fixed bridge that makes pad changes a hassle, the pins aren't much of a problem, I made a relieved punch that makes quick work of it.
I have the same calipers on a Cayman S, and to make things worse, Porsche considers caliper bolts a one time use item that's torqued to near deformation. But they were a worthwhile improvement over the OEM brakes for me.
What I consider a larger problem is pad availability, the Ferodo compounds I used sucked (1000(comes w/kit) and 3000 series I believe), I don't like Porterfields but the custom-cut Performance Friction PFC-01 were quite good despite pad material transfer the first few times at the track.
Pagid now makes the 29 yellow pads for this caliper in narrow and wide, but they are a heart-stopping $700 per axle. I have a set to try out soon.
