Project Mu HC+ R3 Brake Pads (REAR)

2023+ Toyota GR Corolla

PHRR004

Overview:

The Project Mu HC+ R3 Rear Brake Pads are engineered specifically for the 2023 and newer Toyota GR Corolla, delivering exceptional braking performance across a wide range of driving conditions. Designed to improve upon the fade resistance of the original HC series, these pads offer reliable stopping power from everyday city driving to spirited sports and circuit use. With a focus on stable high-temperature performance and precise pedal feel, the HC+ R3 pads are an ideal upgrade for enthusiasts seeking enhanced control and durability without compromising comfort or safety.

These brake pads are crafted to work harmoniously with modern electronic control systems and ABS, providing consistent braking response that aligns with pedal pressure. Whether you are navigating tight corners on the track or managing stop-and-go traffic, the HC+ R3 pads maintain confidence-inspiring performance.

Key Features:

Project Mu’s HC+ R3 brake pads incorporate advanced technology and thoughtful design to maximize braking efficiency and reliability:

• Super Graphite Metallic Material: Ensures strong friction performance and durability under a wide temperature range.
• Wide Operating Temperature: Effective from 50 to 700 degrees Celsius, suitable for both street and track conditions.
• High Friction Coefficient: Ranges between 0.39 and 0.49 mu for consistent and powerful braking force.
• Gas and Dust Removal Slits: Center slits efficiently discharge gases and pad residue generated during intense braking, reducing fade and maintaining stable braking power.
• Chamfered Edges: Pad corners are chamfered to minimize unpleasant brake squeal caused by corner contact.
• Pre-Heat Treated: Pads are pre-quenched to burn off unnecessary materials, reducing gas generation and fade during initial use.
• Reinforced Backplate: Steel backplates are 20% stronger than OEM to prevent warping and ensure pad integrity under high pressure.
• Optimized for Electronic Controls: Designed to work seamlessly with ABS and other electronic braking systems for precise pedal feedback.

Construction & Design:

The HC+ R3 pads utilize a Super Graphite Metallic friction material that balances aggressive stopping power with durability and fade resistance. This advanced compound maintains consistent friction levels even at elevated temperatures, making it suitable for both street and track environments. The pads feature a robust steel backplate engineered to be 20% stronger than standard OEM plates, preventing distortion under heavy braking loads and ensuring the friction material remains securely bonded.

Special attention is given to the pad design with chamfered edges to reduce noise and slits that allow gases and debris to escape, preserving braking efficiency and pedal feel. Additionally, the pads are pre-heat treated during manufacturing to eliminate excess volatile materials, minimizing the risk of brake fade and ensuring reliable performance right from the break-in period.

Performance & Sound

Project Mu HC+ R3 brake pads deliver stable and powerful braking performance with a friction coefficient between 0.39 and 0.49 mu, providing confident stopping power in a variety of driving scenarios. The pads’ design minimizes brake fade by efficiently venting gases and residue generated during high-temperature braking. Chamfered edges help suppress unpleasant squealing noises commonly associated with aggressive pads, though some brake noise may still occur due to rotor condition, dust, or environmental factors.

Installation & Fitment:

These brake pads are a direct fit replacement for the rear brakes of the 2023 and newer Toyota GR Corolla. Installation requires no modifications and can be performed using standard brake service procedures. It is important to allow a proper break-in period after installation, as braking force will be reduced until the pads and rotors reach optimal operating temperature. This ensures the pads bed in correctly for maximum performance and longevity.

What's Included:

• Set of Project Mu HC+ R3 Rear Brake Pads
• Pre-installed shims and chamfered edges for noise reduction
• Installation instructions and break-in guidelines

Ideal For:

The Project Mu HC+ R3 Rear Brake Pads are ideal for Toyota GR Corolla owners who demand superior braking performance for daily driving, spirited road use, and occasional track sessions. Enthusiasts looking to upgrade from stock pads to a high-quality, fade-resistant compound that offers excellent pedal feel and durability will find these pads an excellent choice. They are especially suited for drivers who want a reliable brake pad that balances street comfort with circuit-capable performance.

Project Mu is a manufacturer specializing in high-performance braking components, including brake pads, rotors, stainless steel braided lines, and fluids. Their products are designed for a range of applications, from street driving to motorsports, offering consistent friction characteristics and reliable fitment across various vehicle platforms.
