What is the benefit of a 2-piece rotor design?

A 2-piece rotor design separates the iron friction ring from the aluminum hat. This allows the iron disc to expand and contract with heat independently, reducing the risk of warping and cracking. The aluminum hat also helps to reduce unsprung weight and dissipate heat.

What does the Type-3 slotting do?

The Type-3 slots are continuous and deep, designed to help sweep away brake pad material, dust, and gases from the friction surface. This keeps the pad cleaner and ensures more consistent contact with the rotor, leading to improved and more reliable braking performance, especially under heavy use.

Do these rotors come with everything needed for installation?

This product includes the 2-piece front brake rotors. It is recommended to refer to the manufacturer's installation instructions for any additional hardware or specific procedures required for proper installation on your vehicle.

Product Details

If you're pushing your 991 GT3 or GT3 RS to its limits on the track or the street, you know how critical consistent braking performance is. These 2-piece front brake rotors from Brembo are specifically designed for your car, offering a significant upgrade over stock components for demanding driving scenarios. They measure 380mm in diameter and are 34mm thick, providing a larger surface area and thermal mass to handle the intense heat generated during hard braking.

What sets these rotors apart is their 2-piece construction. The rotor disc is made from a high-carbon iron alloy, chosen for its excellent thermal properties and resistance to cracking under stress. This disc is then mounted to a lightweight, anodized aluminum hat. This design allows the disc to expand and contract freely with temperature changes, reducing the risk of warping and improving overall rotor life. The aluminum hat also helps to shed heat away from the hub assembly and reduces unsprung weight, which can benefit handling. Brembo's Type-3 slotting pattern is a key feature for performance driving. These deep, continuous slots help to sweep away brake dust and gases that can build up between the pad and rotor surface. This keeps the pad surface cleaner and allows for more consistent friction, meaning you get reliable stopping power lap after lap, or during spirited drives.

This set is designed as a direct replacement for your factory front rotors, excluding models equipped with Porsche Ceramic Composite Brakes (PCCB). You'll be installing a well-built component from a respected name in braking technology, ensuring you have the stopping power needed to match your GT3 or GT3 RS's performance capabilities. Make sure to refer to the manufacturer's installation instructions for proper mounting and break-in procedures.
