These are 2 sets (pairs) of Porsche 914-6 Steel Rear Calipers, as well as 2 sets (pairs) of 914-6 GT Steel Rear Calipers
(the GT calipers are the ones with the steel spacers to allow the use of a vented rotor).

The 914-6 standard calipers will be converted to the GT spec. by simply adding the steel spacers.
All calipers will be completly rebuilt to "like-new" condition including new cad-plating,
hardware, stainless-steel pistons, o-rings, seals, etc. Stay tuned!
