GiroDisc Porsche 911 Carrera S/4S/GTS (991.1) 350mm Slotted Front Rotors

These GiroDisc 350mm front rotors are built with a unique two-piece design, featuring a floating hat made from anodized aluminum and a high-carbon iron rotor ring. This construction is key to managing heat effectively, especially during spirited driving or track use. The anodized aluminum hat not only looks sharp but also helps prevent corrosion and reduces overall weight compared to a traditional one-piece rotor. The rotor ring itself is slotted, which is a notable design choice that helps to vent gases and dissipate heat more efficiently than a plain rotor.

The GiroDisc rotor ring is cast from a proprietary high-carbon iron alloy, chosen for its strength and thermal stability. This material is crucial for resisting the warping and cracking that can occur under heavy braking loads. The slots are precisely machined to help sweep away brake dust and gasses that can build up between the pad and rotor surface, ensuring consistent braking performance. This design is particularly beneficial when you're pushing your Porsche 911 Carrera S, 4S, or GTS (991.1) hard, as it helps maintain pad effectiveness and reduces the risk of brake fade.

When installing these rotors, you'll find they are designed as a direct replacement for your factory front rotors, making the swap straightforward. The floating design allows the rotor ring to expand and contract freely with temperature changes, which further contributes to preventing stress cracks and maintaining rotor integrity over time. This attention to detail in materials and design means you get improved braking performance and durability for your high-performance Porsche.
