I bought took the car out of long term ownership and medium term hibernation last summer. I drove it a few hundred miles with no issues and have been working on it since. Currently upgrading and these are now spares. (2 calipers, 2 rotors, bearings) As the saying goes, everything worked fine when parked last summer! I do have a 2013 receipt for the RF caliper as a parts house rebuild. I'm guessing less than 500 miles on the car since. All bleed screws are free, textar pads look virtually new. Representive wear shown. Bearing races look good and bearings are actually German, so these go back a ways!
No idea what they are worth to someone but happy to be educated. I think it will all fit in an "if it fits it ships" USPS box so that might save a bit on shipping.
