Ciao!
here some of the upgrades that i've done today ;)

I did some particular on the upper side....








Then i did a big fillet by sweep on the lower side then i've added the two fixing holes and to the end i added two reinforcing rib.


















And then i added a lot of fillets to the caliper body, two new parts (a clip and a pin) and i did the pistons holes.
