GiroDisc rear rotors for the Porsche 911 GT3 (991), a direct replacement for the rear OE iron disc on the 991 GT3 and GT3 RS. No modifications are necessary and unmodified factory pads can be used.
Key Features
- Bolts directly to the car and works with the OE calipers
- Lightweight 6061-T6 aluminium hat with GiroDisc's own cast iron ring, machined in house
- Curved vane design acts as a centrifugal pump to force cooling air through the disc
- Floating mount on high strength alloy steel drive pins with anti-noise spring washers, so the ring self centres between the pads
- Keeps the factory brake bias and ABS efficiency, unlike a big brake kit; only the cast iron ring needs replacing when worn
