GiroDisc Porsche 911 GT3/GT3RS/GT2RS (991 2014-2019) w/PCCB (Iron Rotor Pad Shape) Slotted Rear Rotors

GiroDisc slotted rear rotors provide direct replacement braking for Porsche 911 GT3 GT3RS GT2RS (991 chassis 2014-2019) equipped with PCCB calipers using iron rotor pad shape. These 2-piece rotors feature high carbon cast iron friction rings attached to lightweight 6061-T6 aluminum hats for reduced unsprung weight and improved heat dissipation. Track drivers rely on them for consistent pedal feel and resistance to fade during extended sessions.

Key Features

  • Slotted Surface: 72 wide slots clear gases debris and water for immediate pad bite and reduced stopping distances in wet dry conditions
  • 2-Piece Construction: Fully floating design with stainless steel bobbin hardware allows thermal expansion prevents hat warping
  • Curved Internal Vanes: Direct cooling air to friction surface lowers temperatures by up to 100 degrees over solid rotors
  • High Carbon Alloy Iron: Resists cracking warping provides stable friction through high heat cycles
  • Lightweight Hats: Forged 6061-T6 aluminum reduces rotating mass by 4 lbs per rotor versus OEM steel equivalents
