Hawk HB521Q.650 DTC-80 Compound Performance Disc Brake Pad Set

The Hawk Performance HB521Q.650 features Hawk's DTC-80 (Dynamic Torque Control) compound, an ultra-high-performance racing brake pad engineered for extreme-duty motorsport and track applications. Designed for vehicles subjected to severe braking demands, the DTC-80 delivers exceptional torque and stopping power at very high operating temperatures where conventional and street-performance pads lose effectiveness.

Key Features:

• DTC-80 compound — Hawk's highest-temperature racing formulation, optimized for operating temperatures between 400°F and 1,600°F (204°C–871°C)
• Outstanding high-temperature friction stability — maintains consistent coefficient of friction under repeated, hard braking events
• Excellent resistance to brake fade — purpose-built for endurance racing, road course, and sanctioned competition use
• Positive mold construction — ensures uniform pad density and consistent performance across the full face of the pad
• Ferro-Carbon compound — provides high torque output and aggressive initial bite suited for race conditions
• Low rotor wear characteristics relative to other compounds in the extreme-duty category
• Chamfered and slotted design reduces noise and helps expel heat and gas buildup

The DTC-80 compound is intended exclusively for closed-course competition and track day use. Because this compound requires elevated operating temperatures to reach optimal performance, it is not recommended for standard street driving. Hawk Performance manufactures the HB521Q.650 to meet the rigorous demands of professional motorsport teams and serious club racers seeking maximum braking performance on demanding circuits.
