Product Description
The **Hawk HB521F.800** brake pads feature the **DTC‑70XL ultra high‑torque compound**, engineered for demanding performance braking applications where aggressive deceleration and thermal durability are key. With an extra‑thick **.800″ friction layer**, this pad set provides increased pad life and heat absorption ideal for track, drag, and heavy‑duty motorsport brake systems.
DTC‑70XL delivers strong initial bite and dependable release characteristics across a wide range of temperatures, giving drivers confident braking performance under repeated heavy load. These pads are designed to pair with **performance calipers** — such as Wilwood BB/SL, AP Racing, Brembo race series, and other aftermarket systems — where standard street pads are not sufficient. They are intended for **iron or steel rotors only** and are *not compatible* with carbon‑ceramic rotors. Always verify pad thickness, pad shape, and caliper compatibility before ordering to ensure proper fitment.
