Project Mu PPR961 Type PS Rear Brake Pads Performance Street Compound

The Project Mu PPR961 is a Type PS (Performance Spec) compound rear brake pad engineered for performance street and sport driving. Developed by Project Mu — a Japanese brake manufacturer with roots in motorsport dating back to 1988 — the Type PS compound delivers a compelling balance of confident stopping power, low brake dust, and reduced noise for drivers who demand more than a standard OE replacement pad.

The Type PS compound is designed to operate across a wide rotor temperature range of 0–500°C, making it equally well-suited to daily commuting and spirited driving. The non-steel, non-asbestos friction material features a friction coefficient of 0.38–0.45, providing progressive, linear brake feel without the harshness or cold-bite inconsistency associated with more aggressive race-oriented compounds.

Key Features:

• Type PS (Performance Spec) compound — Project Mu's street-sport formula offering improved anti-fade performance over OE pads
• Non-steel, non-asbestos friction material — safer formulation compatible with vehicle inspection requirements
• Friction coefficient: 0.38–0.45 — linear, predictable pedal response
• Operating temperature range: 0–500°C — effective from cold starts through sustained sport driving
• Low dust and low noise — designed to minimize wheel contamination and brake squeal
• Compatible with radial tires and larger aftermarket wheels
• Rear axle fitment — direct OE-style replacement installation

Project Mu has been a trusted name in performance braking since 1988, with a heritage that spans WRC, D1 Drifting, and endurance racing. The PPR961 brings that engineering expertise to the street in an accessible, everyday-ready package.
