DFC Geoperformance Rotor - Drilled and Slotted Product Line

The DFC Geoperformance Rotor - Drilled and Slotted line focuses on rotors that combine drilled holes and slots to improve brake pad bite and aid in heat and gas dissipation. This design helps maintain braking efficiency under demanding conditions. The rotors feature a rust-resistant coating and a Geospec silver grey hat finish, enhancing durability and corrosion resistance for extended service life.

Detailed Product Description

This Dynamite Friction disc brake rotor is specifically designed for use on Cadillac, Chevrolet, and GMC models including the Escalade, Escalade ESV, Sierra 1500, Sierra 1500 Limited, Silverado 1500, Silverado 1500 LTD, Tahoe, VISTIQ, Yukon, and Yukon XL. The rotor’s vented construction allows for improved airflow to reduce heat buildup during braking. The directional drilled and slotted surface helps evacuate brake dust, water, and gases, which can improve braking response and reduce fade. The rotor’s nominal thickness of 30 mm ensures durability, while the discard thickness of 28 mm indicates when replacement is necessary to maintain safe braking performance.

Applications and Problem Solving

• Reduces brake fade during heavy towing or hauling
• Improves braking performance in wet or dusty conditions
• Helps prevent rotor warping from excessive heat
• Maintains consistent brake pad contact and bite
• Protects against corrosion with rust-resistant coating

Installation Notes and Tips

Ensure the rotor is installed on compatible vehicles such as the Chevrolet Silverado 1500 or GMC Yukon with the correct bolt pattern (6 bolts, 16 mm diameter). Verify rotor thickness before installation and replace if below the discard thickness of 28 mm. Properly torque lug nuts to manufacturer specifications to avoid rotor damage. The directional surface requires installation in the correct rotation direction for optimal performance.

Quality Assurance

Dynamite Friction rotors are manufactured to meet OEM specifications for fit and function. The rust-resistant coating and Geospec silver grey hat finish provide added protection against corrosion. While no specific warranty information is provided, adherence to discard thickness and proper installation will ensure reliable braking performance.
