Product Description

The GiroDisc D2-032 is a rear slotted replacement rotor ring set for Porsche 911 models across the 996, 997, 991, and 992 generations as well as the 987 Cayman S/R -- all vehicles equipped with 350mm rear iron rotors (non-PCCB). Sold as a pair with replacement hardware, the D2-032 rings replace worn friction rings on existing GiroDisc A2-032 rear rotor hats, allowing the lightweight aluminum hat and drive pin hardware to be reused indefinitely. The proprietary high-carbon cast iron is poured and machined entirely in the USA at GiroDisc's Bellingham, WA facility.

Slotted curved vane design provides continuous cooling, gas evacuation, and water dispersal for consistent braking on street and track. Anti-noise spring clips allow thermal expansion while eliminating cold rattle. Factory brake bias and ABS function fully maintained. Requires existing GiroDisc A2-032 hat -- not compatible with OEM 1-piece hats, PCCB-equipped vehicles, or Carrera base models with 330mm rear rotors.
