Dynamic Friction rncWFWH1-63147 GeoSpec Coated Drilled and Slotted Front Brake Rotor

The Dynamic Friction rncWFWH1-63147 (634-63147) is a GeoPerformance drilled and slotted disc brake rotor featuring DFC's proprietary GeoSpec corrosion-resistant coating. Engineered to meet or exceed OEM specifications, this front rotor delivers enhanced braking performance with superior durability and rust protection.

GeoSpec Coating Advantages:

• Patented silver-gray finish — fights rust far better than conventional paint or zinc coatings
• Processed dry and shipped dry — ready to install with no additional preparation or degreasing required
• The coating is safely swept away by brake pad friction material with no harmful effects
• Superior cyclic corrosion protection tested to withstand 400+ hours of salt spray (SAE J2334, GMW 14872)

Drilled and Slotted Performance Features:

• Cross-drilled holes dissipate heat buildup during braking and are chamfered to reduce the potential for cracking
• Machined slots evacuate brake dust and road debris, preventing pad glazing for consistent bite
• Drilled and slotted design provides shorter stopping distances, particularly in wet weather conditions
• OE vane configuration ensures proper and maximum heat dissipation

Precision Manufacturing:

• Cast from premium G3000/G11H18 iron for strength, stability, and long-term durability
• Machined to the tightest tolerances using state-of-the-art equipment
• Non-directional surface finish promotes faster, more even brake pad bed-in for quieter, smoother stops
• Vented rotors are 100% inspected for balance and electronically corrected as needed
• Each rotor passes a 100% electronic inspection measuring all critical attributes to confirm OE specification compliance

The Dynamic Friction 634-63147 GeoSpec drilled and slotted rotor is a direct-fit, performance-oriented upgrade designed to restore and improve braking system reliability — installed in the same time as a standard brake job with no extra prep work required.
