Project Mu PBR911 B-Spec High-Performance Street Light Track Brake Pad Set

The Project Mu PBR911 B-Spec Brake Pads are engineered for drivers who demand strong initial bite and reliable fade resistance without sacrificing everyday street manners. Built around Project Mu's proprietary Hyper Carbon B compound, the B-Spec formula bridges the gap between daily street driving and light track day use — delivering consistent, confident stopping power in both environments.

The B-Spec compound operates effectively across a rotor temperature range of 0–500°C, making it well-suited for performance street driving where brake temperatures can climb during spirited use. With a friction coefficient of 0.32–0.42, these pads provide progressive, linear braking feel that inspires driver confidence without the aggressive initial grab typical of full race compounds.

Key Features:

• Compound: Hyper Carbon B — Project Mu's purpose-built street/light track formulation
• Operating Temperature Range: 0–500°C (32–932°F)
• Friction Coefficient: 0.32–0.42 for progressive, predictable braking feel
• Low Dust Formula: Excellent dust characteristics for cleaner wheels on the street
• Rotor-Friendly: Gentle on rotors even under track day heat cycles, extending rotor life
• Applications: Street driving, performance driving, and light track duty

Project Mu is a Japanese performance brake brand renowned in motorsport and enthusiast communities for compound consistency and quality. The B-Spec pads are an ideal upgrade for performance street vehicles looking to improve braking authority over OEM pads while remaining practical for daily use.
