Detailed Product Description
This Dynamite Friction rotor is part of the DFC Geoperformance Rotor - Drilled and Slotted line, which focuses on delivering reliable braking performance through advanced rotor surface technology. The drilled and slotted design helps to reduce brake fade by allowing gases and heat to escape more efficiently during braking. The rotor is solid rather than vented, providing a consistent braking surface with an overall height of 40.9 mm and a center hole diameter of 71.7 mm. The rotor’s hat is finished in Geospec silver grey, which adds a layer of corrosion resistance, complemented by a rust resistant coating on the disc surface. This rotor is designed specifically for Mazda 3 and Mazda 3 Sport vehicles, ensuring proper fitment with its 5 lug holes and 114.3 mm bolt circle diameter.
Applications and Problem Solving
- Improves braking performance for Mazda 3 and Mazda 3 Sport models
- Reduces brake fade during aggressive or repeated braking
- Helps prevent rotor warping caused by excessive heat buildup
- Minimizes rust and corrosion for longer rotor life
- Maintains consistent braking feel with directional drilled and slotted surface
Installation Notes and Tips
Ensure the rotor is installed on compatible Mazda 3 or Mazda 3 Sport models using the correct lug pattern and bolt circle diameter. Verify the rotor thickness before installation; replace if below the discard thickness of 9 mm. Clean the rotor surface to remove any protective coatings or debris before mounting. Proper torque specifications should be followed for lug nuts to avoid rotor damage or uneven wear.
Quality Assurance
Dynamite Friction manufactures the DFC Geoperformance Rotor - Drilled and Slotted to meet or exceed OEM standards for fit, form, and function.
