Brembo 14-19 991 GT3/991 GT3RS (Excl PCCB) Front 2-Piece Discs 380x34 2pc Rotor Slotted Type-3
Brembo 103.9020A front 2-piece brake rotors deliver track-proven stopping power for 2014-2019 Porsche 991 GT3 and GT3 RS models excluding PCCB. The 380x34mm slotted Type-3 design combines a 6061-T6 aluminum hat with high-carbon steel friction surface to shed 4.4 lbs (2 kg) per rotor versus OEM one-piece discs. This setup maintains thermal stability during repeated hard braking for reliable performance on road or circuit.
Key Features
- Two-Piece Construction: Aluminum center section with floating high-carbon steel ring cuts rotational inertia enhances handling response and suspension feel
- Type-3 Slot Pattern: Curved slots clear gases water and debris while directing cooling air to pads for fade-free braking and extended pad life
- 380x34mm OEM-Match Sizing: Precision dimensions ensure drop-in compatibility with factory GT3 calipers and hub mounting
- High-Carbon Alloy Steel: Resists thermal cracking and warping under extreme loads from track sessions or aggressive street use
- Fully Floating Mount: Accommodates differential expansion between hat and ring prevents cone distortion preserves flatness
Product Notes
- Designed exclusively for non-PCCB equipped vehicles verify your setup before purchase
- Includes dedicated left and right rotors for precise balance and bedding
- Oversized heavy components expect dimensional weight pricing on carrier quotes
Installation Notes
- Professional installation recommended.
- Bolt-on replacement torquing to Porsche specs cleans hub mating surface thoroughly
- Uses OEM caliper hardware and wheel clearance unchanged from factory

Brake Rotors
Brake rotors work with brake pads to bring your vehicle to a controlled stop. Upgrading from worn or stock rotors to a performance or OE-quality replacement improves braking consistency, reduces fade, and restores the original factory feel. Popular ProductsPopular brake rotor choices include EBC Brakes USR slotted rotors, Brembo OE-replacement rotors, StopTech Sport cross-drilled and slotted rotors, and Centric Premium rotors for OE-quality service replacement.
