GiroDisc Porsche 911 Turbo/Turbo S (991 Excl PCCB) Slotted Rear Rotors

GiroDisc slotted rear rotors deliver direct replacement braking upgrades for 2014-2019 Porsche 911 Turbo and Turbo S models on the 991 chassis excluding PCCB systems. The curved slot pattern expels brake gases and debris for consistent stopping power during spirited driving or track sessions. Two-piece construction with aluminum hats reduces unsprung weight by 5.1 lbs per rotor compared to OEM steel units improving suspension response and acceleration.

Key Features

  • Curved Vane Slotted Surface: Channels heat and gases away from the pad interface reducing fade and maintaining grip in high-heat conditions
  • Two-Piece Build: 6061-T6 aircraft-grade aluminum hats with high-carbon alloy rotor rings cut 10.2 lbs total weight per pair while retaining full rigidity
  • Black Zinc Geomet Coating: Shields rotors from rust and corrosion extending service life in harsh environments
  • 350 x 30mm Dimensions: Matches OEM rear specs of 13.78 inches diameter and 1.18 inches thickness for plug-and-play fit
  • Hard Anodized Hats: Lightweight hats resist wear and galling during repeated high-load use

Product Notes

  • Sold as a pair including left and right rotors
  • Follow GiroDisc bedding procedure after installation for peak performance
  • Excludes vehicles equipped with Porsche Ceramic Composite Brakes (PCCB)

Installation Notes

  • Professional installation recommended.
