Whether you're pushing your vehicle on the track or engaging in spirited driving, the D1 Spec pads deliver consistent, fade-resistant braking power to help you maintain control and confidence.

Constructed for rear-brake use, these pads excel in providing excellent friction characteristics while maintaining durability. Their specialized formulation ensures optimal performance during high-temperature maneuvers common in drifting and aggressive driving, making them a perfect upgrade for enthusiasts looking to enhance their vehicle's braking response without sacrificing reliability.

Key Features

Project Mu's D1 Spec brake pads incorporate advanced materials and design features to deliver superior braking performance. Here are some of the key aspects:

• Super Graphite Metallic Material: Crafted from a high-performance metallic compound, these pads offer excellent friction levels and thermal stability, ensuring consistent braking even during prolonged use.
• Optimized Friction Coefficient: With a friction coefficient ranging from 0.50 to 0.60, the D1 Spec pads provide strong initial bite and reliable stopping power, crucial for drifting and high-performance driving scenarios.
• Temperature Range: Designed to operate effectively within rotor temperatures of 0-380°C, these pads resist fade and maintain performance during aggressive maneuvers.
• Exclusive Rear Application: Tailored specifically for rear brakes, ensuring perfect fitment and balanced braking response when paired with compatible front components.
• Durability and Reliability: Engineered to withstand the rigors of drifting and spirited driving, these pads offer long-lasting performance with minimal fade.
• Low Dust and Noise: Designed to produce less brake dust and operate quietly, keeping your vehicle cleaner and your driving experience more comfortable.

Construction & Design

The Project Mu D1 Spec brake pads feature a high-quality metallic compound bonded to a durable backing plate, ensuring consistent contact and minimal wear. The super graphite metallic material provides excellent heat dissipation, reducing the risk of brake fade during intense use. The pads are precisely machined to fit the rear calipers of the Toyota Corolla GTS models from the mid-80s, ensuring a perfect, secure fit without the need for modifications.

The design emphasizes thermal stability and friction consistency, making these pads suitable for drifting, track days, and aggressive street driving. Their construction minimizes noise and dust, contributing to a cleaner, quieter braking experience while maintaining high performance under demanding conditions.

Installation & Fitment

The Project Mu D1 Spec brake pads are designed as direct replacements for the rear brakes on 1985–1987 Toyota Corolla GTS and Sport GTS Coupe models. Installation is straightforward for those familiar with brake service, as they utilize the factory mounting points and hardware. No special tools or modifications are required, and the pads are compatible with existing rear calipers. For optimal performance, it is recommended to replace brake pads in pairs and inspect the rotors for wear.
