Brembo 14-19 991 GT3/991 GT3RS (Excl. PCCB) Front 2-Piece Discs 380x34 2pc Rotor Slotted Type-3

Brembo front 2-piece slotted rotors deliver track-ready stopping power for 2014-2019 Porsche 991 GT3 and GT3 RS models excluding PCCB. The 380x34mm design with Type-3 slots sheds heat and water fast for consistent brake feel under hard use. Aluminum hats cut unsprung weight versus stock one-piece rotors improving suspension response and driver confidence.

  • 380x34mm Dimensions: Matches OEM specs for direct bolt-on fit with 15mm radial runout tolerance ensuring smooth operation
  • High-Carbon Alloy: Resists warping and cracking at high temperatures over 1000°F for reliable performance on street or track
  • CAD/CAM Engineered: Finite element analysis optimizes stress distribution for maximum durability and consistent wear
