Features

• DTC-30 compound delivers controllable torque with smooth, consistent initial bite and superior pedal feel.
• Effective from cold - operates across a wide 100-1200°F temperature range.
• Excellent release characteristics reduce brake drag and improve modulation.
• Very low rotor wear compared to higher-torque DTC compounds.
• Multi-purpose compound suited for road racing, dirt track, drag racing, and circle track use.
• Proven in NASCAR Modified, Trophy Trucks, Pro Buggies, and Open Wheel applications.
• Ferro-Carbon construction provides high fade resistance under sustained heavy braking.
• Can be used on both axles of lightweight sport vehicles or paired with DTC-60/70 for split-friction setups.

Product Description

The Hawk HB148W.560 DTC-30 front brake pads are engineered for competitive motorsport use on lightweight sport compacts, specifically the 1990-1993 Mazda Miata, Geo Storm, and Isuzu Impulse. Built around Hawk's Dynamic Torque Control 30 (DTC-30) compound, these pads are designed for drivers who prioritize smooth, controllable braking over outright maximum bite. The DTC-30 compound is effective from cold temperatures and delivers consistent, progressive pedal feel across its wide operating range - making it well suited for both track day use and race applications where precise torque control is critical.

The DTC-30 is a popular choice for Spec Miata competitors and can be run on both front and rear axles of small, lightweight race cars, or used in a split-friction setup paired with a more aggressive compound on the front. Expect increased dust and noise compared to street pads - this is a purpose-built race compound. Proper bed-in procedure is recommended before competitive use to ensure optimal friction film transfer and maximum stopping performance.
