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 consistent braking performance under demanding conditions. The rotors feature a vented construction to further reduce heat buildup, and a rust-resistant coating to extend service life. The Geospec silver grey hat finish adds corrosion resistance and a clean appearance.

Technical Details and Specifications

This disc brake rotor features a nominal thickness of 23 mm and a discard thickness of 21 mm, ensuring it meets safety standards for replacement intervals. The rotor’s 282 mm outside diameter and 47.1 mm overall height are engineered to fit specific vehicle brake assemblies precisely. The drilled and slotted surface is directional, designed to optimize water and debris evacuation while improving pad contact. The rotor includes five bolt holes with a 12.6 mm diameter and a bolt circle diameter of 114.3 mm, matching the lug pattern of compatible Acura, Honda, and Isuzu models.

Applications and Problem Solving

• Reduces brake fade caused by excessive heat during prolonged braking
• Improves wet weather braking by channeling water away from the rotor surface
• Minimizes brake dust buildup on the rotor surface
• Helps maintain consistent brake pad contact and performance
• Prevents rust and corrosion with a protective coating for longer rotor life

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 21 mm before installation. Clean the rotor surface to remove any protective oils or residues prior to mounting. Verify bolt hole alignment and torque lug nuts to manufacturer specifications. This rotor is directional; install with the correct orientation to maintain optimal performance. Compatible with vehicles including Acura RL, TL, Honda Odyssey, Prelude, and Isuzu Oasis.

Quality Assurance

Dynamite Friction rotors are manufactured to meet or exceed OEM specifications for fit, form, and function. The rust-resistant coating and precision machining contribute to durability and consistent braking performance. While no specific warranty information is provided, the product is designed for reliable service life when installed and maintained according to vehicle manufacturer guidelines.
