If you're doing front & rear, you'll need 930 rotors & calipers, 930 hubs for the front. You'll either have to machine the rear calipers to fit the SC mounts or have customs mounting tabs welded onto your SC trailing arms and make new brake lines to the rear calipers. I'm probably forgetting some things, too. You're probably looking anywhere between $2500 to $4K depending how much you can do yourself and how much you pay for the parts. It's nice to have but really unnecessary for the street. For street use the 944Turbo front calipers with Carrera rotors are a good and inexpensive upgrade. The only modification is that one of the mounting holes on the caliper needs to be slightly elongated for the bolts to line up with the threaded holes on the SC struts.
