Most of the set-ups I've seen use the bigger calipers but the metric calipers are similar so I would imagine they are being used too. The Intermediate calipers measure about 7" from center to center of the mounts while the metric calipers are about 5.5".

I checked on the Willwood calipers and they actually make replacements for both the intermediate and metric calipers under the GMIII name. There are several different part #'s depending on piston size and rotor thickness.
