    Zimmermann 20 mm vented rear rotors

    I have a pair of 944 NA Zimmermann rotors cut 2 mm to fit rear SWB caliper cars with spacers for vented rotors. They have about 10,000 miles on them and still measure 20 mm as they were cryo treated when new. The reason for selling is I went to a 42 mm piston ATE caliper and needed the 2 mm back. I had to move the caliper 3 mm forward to clear the parking brake part of the rotor as the piston area is much bigger then the 35 or 38 mm stock calipers.
    $100.00 plus shipping and paypal fees. The cryo treatment cost me $200.00 5 years ago. They were done by Windberg Crankshafts out of Denver. Unfortunitly Randy has retired and my new ones won't get his personal service.
