I've got a set of 18z calipers that I wanted to put on my S6, but haven't had any luck finding a rotor that will work, so I'm selling them.

These will bolt right up the a B6/B7 S4, with either modified ML55 rotors, or the 2 piece rotors that Girodisc/JHM sell.

Located in Billings, MT. Want $650 shipped for the pair.
