So after the install, you can see the pads use 100% of the rotor surface and the pads are bigger, so, in my opinion, that loss of area on the piston side (the 6-pot calliper apparently provide less area than the single 60mm piston calliper) is compensated by the massive difference on the pad side.
A few comments on what I noticed right after the install
1. the pedal is about 20% firmer, I was actually expecting a bigger change, but was also afraid it could be too hard, so I am fine with the improvement I am seeing. Also, the original setup for some reason had a soft pedal feel along the whole pedal travel, with not much change in pedal feel in proportion to pedal travel and brake force; with the 6-pots, the pedal starts to become firmer as the pedal is pushed further and the brake force increases, which I like. You are still able to trigger the ABS if you go deep on the brake pedal (this does not require much force v stock, it is just firmer). The issue with the OE setup is that it required very little force, which I did not like.
2. I did not see any change in normal driving behaviour, nor I would say there was a change in the braking power at all. All in I like the new feel as I have better feedback on how much braking I am applying versus travel and firmness of the pedal.
Next, I will install my rear 996 Brembos along with new lines and then a complete brake fluid flush, which should complete the package

And of course, it looks better
