What is the benefit of a two-piece rotor design?

A two-piece rotor features a separate hat and rotor ring. This allows the rotor ring to expand and contract with heat independently, which helps prevent warping and cracking. It also typically reduces unsprung weight compared to a single-piece rotor.

What does the Type 3 slotting pattern do?

The Type 3 slotting pattern on these rotors is designed to help sweep away brake dust and gases that can build up between the brake pad and rotor surface. This helps maintain consistent friction and can improve braking performance, especially during repeated hard stops.

Are these rotors compatible with all 991.1 models?

These rotors are specifically designed for the 2012-2016 Porsche 911 Carrera S (C2S), Carrera 4S (C4S), and GTS models. They are not compatible with vehicles equipped with the Porsche Ceramic Composite Brakes (PCCB) system.

Product Details

What you get with this Brembo order are two rear brake rotors, specifically designed as a two-piece assembly. These rotors measure 350mm in diameter and are 28mm thick, featuring a Type 3 slotting pattern. They are intended for the rear axle of 2012 through 2016 Porsche 911 models, including the Carrera S (C2S), Carrera 4S (C4S), and GTS variants, provided they do not have the Porsche Ceramic Composite Brakes (PCCB) system.

Brembo's two-piece rotor design is a step up from traditional single-piece rotors. The floating hat design allows the rotor ring to expand and contract freely with temperature changes, which helps prevent rotor warping and cracking under heavy use. This construction also reduces unsprung weight compared to a one-piece rotor, which can contribute to better handling. The Type 3 slotting pattern is engineered to help sweep away brake dust and gases from the pad surface, maintaining consistent friction and improving braking performance, especially during repeated hard stops. This makes them a solid choice for drivers who push their vehicles and demand reliable stopping power.

When installing these rotors, remember they are a direct replacement for the original equipment, but it's always a good idea to consult your vehicle's service manual or a professional mechanic for the correct installation procedures. Ensuring the caliper hardware is clean and the mounting surfaces are free of debris will help achieve optimal performance and longevity from these high-performance brake discs.
