• Directional slotted and drilled surface for improved brake pad bite and cooling
• Solid rotor construction with a nominal thickness of 12 mm and discard thickness of 10.4 mm
• Rust resistant coating with Geospec silver grey hat finish
• 5 bolt holes with 16.6 mm diameter and 127 mm bolt circle diameter
• Overall diameter of 316 mm and height of 76.5 mm

Detailed Product Features and Specifications

This Dynamite Friction rotor is part of the DFC Geoperformance Rotor - Drilled and Slotted line, which focuses on delivering enhanced braking efficiency through advanced surface design. The rotor’s slotted and drilled surface helps to evacuate gases, dust, and water, reducing brake fade and maintaining consistent stopping power under demanding conditions. The directional brake surface is optimized for the rotational direction of the rotor, ensuring maximum performance and longevity.

The rotor is solid rather than vented, providing a robust and durable braking surface. It has a nominal thickness of 12 mm and a discard thickness of 10.4 mm, which indicates when the rotor should be replaced to maintain safe braking. The hat section features a Geospec silver grey finish that offers corrosion resistance, complemented by an overall rust resistant coating to extend the rotor’s service life.

Applications and Problem Solving

• Replacement rotor for worn or warped rotors on Jeep Wrangler and Wrangler JK
• Improves heat dissipation to reduce brake fade during off-road or heavy braking
• Helps maintain consistent braking performance in wet or dusty conditions
• Addresses rotor surface glazing and uneven pad wear
• Restores proper rotor thickness and braking efficiency

Installation Notes and Tips

Ensure the rotor is compatible with your specific Jeep Wrangler or Wrangler JK model year before installation. Clean the hub surface thoroughly to prevent rotor runout. Use proper torque specifications on the 5 lug bolts (16.6 mm diameter) to secure the rotor. Since this rotor has a directional surface, install it according to the indicated rotation direction for optimal performance.
