I have a pair of 18z 6-piston front calipers from a Porsche Cayenne for sale.
I will be refinishing them to the buyers spec with new seals, over cured paint, and new cast-vinyl hi-temp decals.

These bolt up to B6/B7 uprights and take a 350mm rotor (works with stock S4 345mm rotor too)

Please see my thread for my previous work.

$680 USD shipped!

PM me if you are interested. Only got 1 set of 18z right now. Will have more in the future.
