Project Mu HC+ R3 Brake Pads (FRONT)

2023+ Toyota GR Corolla

PHRF009

Overview:

The Project Mu HC+ R3 brake pads are engineered specifically for the front brakes of the 2023 and newer Toyota GR Corolla. Designed to deliver exceptional braking performance across a wide range of driving conditions, these pads excel from everyday city driving to spirited sports driving and even circuit use. They offer enhanced fade resistance compared to previous HC series models, ensuring consistent stopping power even under demanding high-temperature conditions. With a focus on pedal feel and control, these pads complement modern electronic brake systems and ABS for a confident driving experience.

Key Features:

Project Mu HC+ R3 brake pads incorporate advanced technology and thoughtful design elements to maximize performance and reliability:

• Super Graphite Metallic Material: Provides a high friction coefficient ranging from 0.39 to 0.49μ for strong, consistent braking.
• Wide Operating Temperature Range: Effective from 50°C up to 700°C, suitable for both street and track conditions.
• Gas and Dust Management: Central slits in the pad surface efficiently discharge gases and pad residue generated by intense friction, reducing brake fade.
• Chamfered Edges: Precision-cut corners minimize unpleasant brake squeal caused by pad corner contact.
• Pre-Heat Treated: Pads are factory pre-quenched to burn off unnecessary materials, reducing initial gas generation and improving break-in consistency.
• Reinforced Backplate: Steel backplates are 20% stronger than standard to prevent warping under heavy braking pressure, ensuring pad integrity and safety.

Construction & Design:

The HC+ R3 pads utilize a super graphite metallic friction material that balances high-temperature stability with excellent pedal modulation. This advanced compound maintains consistent friction levels even when the brakes reach extreme temperatures, making it ideal for aggressive driving and track use. The pads feature a robust steel backplate engineered to resist distortion and maintain structural integrity under intense braking forces. Additionally, the chamfered edges and central slits are carefully designed to reduce noise and improve pad longevity by managing heat and debris effectively.

Performance & Sound

These brake pads deliver stable and powerful braking performance with a friction coefficient optimized for both street and circuit applications. The design minimizes brake fade by efficiently venting gases and debris, ensuring consistent pedal feel throughout extended use. While the chamfered edges help suppress brake squeal, some noise may still occur due to factors such as rotor condition, dust, rust, or weather. Proper break-in is essential to achieve optimal performance and reduce initial braking force variability.

Installation & Fitment:

Project Mu HC+ R3 brake pads are a direct fit replacement for the front brakes of the 2023 and newer Toyota GR Corolla. Installation requires no modifications, but it is important to allow a proper break-in period after installation. Initially, braking force may be reduced until the pads and rotors reach operating temperature. Following the recommended break-in procedure ensures maximum performance and longevity.

What's Included:

• Set of front brake pads for Toyota GR Corolla 2023+
• Installation instructions and break-in guidelines

Ideal For:

These brake pads are ideal for Toyota GR Corolla owners seeking a versatile, high-performance upgrade that performs reliably in daily driving, spirited road use, and occasional track sessions. Enthusiasts who demand improved fade resistance and pedal feel without sacrificing street manners will find the HC+ R3 pads an excellent choice.
