About the Brembo PRIME Product Line

The Brembo PRIME line focuses on delivering premium-grade brake components that balance performance and durability. This product line is designed to meet the rigorous demands of high-performance vehicles like Porsche models, providing reliable stopping power and resistance to wear. The 09.D931.11 rotor exemplifies the PRIME line’s commitment to quality materials and precise manufacturing standards.

Detailed Product Description

This Brembo disc brake rotor 09.D931.11 is constructed from high carbon cast iron, which enhances thermal conductivity and reduces the risk of warping under heavy braking conditions. The vented full cast design allows for efficient heat dissipation, helping maintain consistent braking performance during aggressive driving or track use. The X drilled surface improves pad bite and helps evacuate gases and debris, contributing to better brake response. Additionally, the rust resistant coating extends the rotor’s service life by protecting against corrosion, an important feature for vehicles exposed to varying weather conditions.

Compatible Vehicles and Applications

• Compatible with Porsche 718 Boxster and 718 Cayman models
• Suitable for Porsche 911, Boxster, and Cayman vehicles requiring a 330 mm rotor
• Ideal for replacing worn or damaged rotors to restore braking efficiency
• Addresses issues such as brake fade, rotor warping, and uneven pad wear
• Helps maintain optimal braking performance for daily driving and spirited use

Installation Notes and Tips

Ensure the rotor thickness is within the specified nominal and discard limits before installation. The 09.D931.11 rotor requires a 5-lug wheel hub with a 98 mm center hole diameter. Proper cleaning of the rotor surface before installation is recommended to remove any protective coatings or residues. Use a calibrated torque wrench to tighten lug nuts to manufacturer specifications to avoid rotor distortion. Note that this rotor does not include an ABS tone ring, so verify compatibility with your vehicle’s ABS system.
