Hawk HB581Q.660 DTC-80 Motorsport Disc Brake Pad 0.660in Thickness

The Hawk Performance HB581Q.660 is a DTC-80 compound motorsport disc brake pad engineered for the most demanding racing environments. Built for serious competitors who push braking systems to their absolute limits, the DTC-80 is a track-only friction compound designed for circle track and road racing venues where maximum brake torque and extreme temperature resilience are non-negotiable.

Key Features:

• Extreme Temperature Range: Ferro-Carbon construction performs from 500°F to 1700°F, maintaining a flat, consistent coefficient of friction at the highest heat levels
• Maximum Brake Torque: Delivers the highest torque values in the Hawk DTC lineup — more brake torque than the DTC-70 — for hard-charging braking zones
• Consistent Corner-to-Corner Performance: Formulated flat friction curve provides predictable, repeatable stopping power lap after lap
• Lower Wear Rates: Track-tested construction offers reduced wear compared to competing race compounds at similar temperature ranges
• 0.660 in. Pad Thickness for precise fitment in compatible calipers
• Race-Proven Confidence: Delivers better car control, more confident brake zone feel, and highly predictable performance under maximum deceleration
• 100% free of asbestos, lead, chromium, cadmium, and antimony
• Manufactured in ISO certified facilities

Important Notes: The DTC-80 compound is intended for track use only and is not suitable for street driving. Not compatible with carbon ceramic rotors. Recommended for experienced racers operating in high-temperature braking environments where less aggressive compounds have proven insufficient.
