Yes, as Bill mentioned, Race Technology/Brembo have stopped selling the 993RS/ 993TT rear rotor with the parking brake bell bolted on for use on a 911. It’s a pretty simple part/modification though to adapt the rotor though is you have access to a machine shop.
The Race Technology Rear GTP kit that came with these rotors use a Lotus Esprit front caliper and a adapter bracket to suit. Bias with 993TT big reds up front is quite rearward though as the Lotus calipers are 36/40 piston size. Race Technology sold then for use with F50 Ferrari front calipers which look like 993TT Big Reds but have 40/44 pistons and a 356mm disk.
Some time later, probably when they stopped wanting to modify the rotors, Race Technology started selling a rear kit that uses 360 Ferrari rear calipers with 28/30 pistons on 930 disks. This bias with 993TT fronts is a bit too much front bias and leaves something on the table.
993RS all around is the best bias setup from what I found if you don’t go for F50 Ferrari fronts and don’t want to run dual master brakes with a balance bar or an adjustable bias valve on a single master setup.
