For sale is a used pair of Essex Designed AP Racing 2-piece Competition J Hook Discs rear that fit on a Porsche 991 GT3 with stock calipers.
The discs are fairly used but still have some life in them. The listing price is essentially for the value of the Hats as these are 2 piece rotors and you can replace the disc rings. MSRP for a complete front pair of ring + hat assemblies is US$1798. Individual disc rings are US$399 each. That puts the value of new hats at US$1000.
