This is a pair of original Porsche 911-S early aluminum front brake calipers that are in very nice condition. Can be used on any year car with 3.5" spacing. I removed the pistons to expose the bores. There are no worm holes or corrosion in the bores. The pistons are aluminum and are in nice shape, one of the pistons has a mark on it, it is pictured and probably still very usable if desired. This pair Will only need seals. Free shipping!
