Either 944t M030 or 964, these cars used the same calipers w/ the piston sizes you mention

Both originally were black and had the same 89mm OC axial mounts, the rears were modified by filling the oe mounting holes and redrilling w/ 3" oc mounting holes. Hopefully these were used w. 930 size 304x32mm front and 309x28mm rear rotors
