Yes outside diameter (OD) of hub.
With the 986 non S caliper theres another option. Use a 84-89 911 carrera rotor (282x24) and itll bolt on like a 944na rear mount rotor(282x20) and match the boxster caliper width (24mm). I build alot of these setups because they fit 15" wheels, whereas the boxster rotor is bigger (298x24) and requires 16"
