Total Performance used to sell these single piston calipers that were polished billet aluminum. Speedway doesn't stock them in anything other than black anodized, nor does Summit, so I tracked them down at Wilwood. The old TP stock number for the polished billet unit was 120-1064D, the number at Wilwood is 120-1064P. I had previously asked Speedway if they would order a set for me if I could track down the correct part number and they said no, so I ordered a set directly from Wilwood.
