Porsche 718 S, 991, 992 911 Carrera Front Rotors (incl. spacers & bolts) Bring race-proven braking performance to your Porsche with Girodisc’s 2-piece floating front rotors. Designed as a direct replacement for the factory rotors and supplied with precision-fit spacers and bolts, this system delivers improved cooling, lighter weight, and more consistent pedal feel under extreme braking. Perfect for the 718 S, 991.2 Carrera, and 992.1 Carrera, these rotors maintain OEM brake balance while drastically enhancing heat control and durability. Performance You Can Feel Every Lap Each Girodisc assembly is precision-machined and hand-finished in the USA from premium materials. The aluminum hat is crafted from 6061-T6 aircraft-grade alloy and anodized for corrosion protection. The iron rings are cast from Girodisc’s proprietary high-carbon alloy, designed for strength and stability under repeated thermal load. The 350mm rotor uses a curved vane design that acts as a centrifugal air pump, pulling cooling air through the rotor to prevent fade and extend pad life. Supplied hardware and spacers ensure exact alignment and fitment to your Porsche’s factory calipers and hub assembly. Vehicle Fitment Porsche 718 Cayman / Boxster S (2017+) Porsche 911 Carrera (991.2 & 992.1 base and S models) Features Direct OEM Replacement: Bolts directly to factory hubs and calipers; includes necessary spacers and bolts for easy installation. Lightweight 2-Piece Design: Reduces unsprung and rotational mass for better handling and braking response. Curved Vane Cooling: Internal vanes pull air through the rotor for optimal cooling and fade resistance. Floating Mount System: Ten high-strength steel pins with anti-noise spring washers allow smooth heat expansion without vibration. Replaceable Rotor Rings: Reuse the aluminum hats—replace only the cast iron rings when worn. Made in the USA: Designed, cast, machined, and assembled under strict quality control at Girodisc’s facility in Washington. FAQs – Porsche 718 S / 991.2 / 992.1 Carrera Front Rotors Do these rotors include all hardware? Yes, each kit comes with spacers and bolts needed for proper installation on OEM hubs and calipers. How do they compare to stock rotors? Girodisc rotors weigh less, cool faster, and handle repeated high-heat cycles better than OEM cast discs. Are they compatible with factory brake pads? Yes, these rotors are designed to work perfectly with OEM or aftermarket pads. Can they handle track use? Absolutely—Girodisc rotors are engineered for consistent performance during aggressive street driving and heavy circuit use. Experience smoother, stronger, and more reliable braking with Girodisc’s front rotor upgrade for your Porsche 718 S, 991.2, or 992.1 Carrera.
