Project Mu PBR261 B-Spec High-Performance Street Brake Pad Set

The Project Mu B-Spec (PBR261) brake pads are engineered for drivers who demand improved stopping power on the street without sacrificing daily drivability. Developed around Project Mu's proprietary Hyper Carbon B compound, the B-Spec formula strikes a practical balance between aggressive initial bite and manageable rotor wear — making it an ideal upgrade for performance street vehicles and occasional track day use.

Designed to combat brake fade under repeated hard stops, the B-Spec compound maintains consistent friction levels across a wide operating temperature range of 0°C to 500°C (32°F to 932°F), with a friction coefficient of 0.32 to 0.42. This makes the B-Spec pads equally capable on a spirited canyon run or a light-duty autocross event.

Key Features:

• Compound: Hyper Carbon B — Project Mu's street-focused carbon compound
• Operating Temperature Range: 0°C – 500°C (32°F – 932°F)
• Friction Coefficient: 0.32 – 0.42 (consistent bite across temp range)
• Low dust formulation — keeps wheels cleaner than many performance compounds
• Rotor-friendly — gentle on rotors even under track day conditions
• Excellent wear characteristics for extended pad life in street environments
• Applications: Street driving, performance driving, light track duty

The Project Mu B-Spec pads offer a meaningful upgrade over OEM brake pads for enthusiasts who want sharper, more confident braking in real-world conditions. Whether commuting or pushing hard on a weekend drive, the B-Spec compound delivers reliable, fade-resistant performance that raises the bar for street brake pad performance.
