Just new pads and rotors will be fine for most people, and the other people probably should step up to a big brake kit. These 4 pots are very popular on rally cars because you can fit 15" wheels around them.
Not sure if this applies to the brz, but on the wrx another common upgrade is to install a legacy caliper bracket and legacy rotors, which are 1" bigger diameter but use the same calipers (same swept area). These shift the bias to the rear even more and together with the 4 pot brakes and SS lines it's an awesome and cheap setup on the wrx. Might be able to do something similar for the BRZ if the parts fit.
Cast iron. They are pretty heavy. I haven't had my BRZ brakes off yet but I would guess they are heavier.
