GiroDisc Porsche 911 GT3/GT3RS/GT2RS (991 Excl PCCB) Slotted Rear Rotors

If you're pushing your Porsche 911 GT3, GT3RS, or GT2RS (991 chassis, excluding PCCB models) to its limits on the track or during spirited driving, you know how critical consistent braking performance is. These GiroDisc slotted rear rotors are built to handle the extreme demands of high-performance driving, offering improved heat dissipation and stopping power when you need it most. They are a direct replacement for your factory rear rotors, designed to work with your existing brake system components.

GiroDisc rotors are well-built using high-carbon iron for the rotor hats and the friction rings. The friction rings are made from a proprietary cast iron alloy that’s known for its durability and resistance to thermal stress. What really sets these apart is the slot pattern. These aren't just decorative; the slots are precisely machined to help vent hot gases and dust away from the pad surface. This action helps prevent pad glazing and keeps the rotor surface cleaner, leading to more consistent braking performance, especially under heavy use. The directional vane design within the rotor also aids in airflow, further assisting with cooling and reducing the risk of brake fade during prolonged track sessions.

When installing these rotors, you'll find they fit right as a direct replacement for your original equipment. They are designed to work seamlessly with performance brake pads, helping you achieve the best possible braking results. For owners who regularly track their vehicles or demand the utmost from their braking system, these GiroDisc rotors offer a significant advantage in performance and reliability.
