Detailed Product Description

This Dynamite Friction disc brake rotor is a solid type rotor with a directional surface pattern combining drilled holes and slots. The drilled holes help vent gases and debris, while the slots assist in cleaning the brake pad surface and improving water dispersion. With a nominal thickness of 11.6 mm and a discard thickness of 10 mm, this rotor ensures a long service life before replacement is necessary. The rust resistant coating and Geospec silver grey hat finish protect against corrosion, which is especially beneficial in wet or humid environments. The rotor’s five-lug bolt pattern with a 112 mm bolt circle diameter and 15.2 mm stud hole diameter ensures proper fitment on Audi A3, Volkswagen Bora, Golf, Jetta, and Jetta City models.

Common Applications and Issues Addressed

• Replacement for worn or warped rotors causing brake pulsation
• Improved heat dissipation to reduce brake fade during heavy braking
• Enhanced braking performance in wet conditions due to slotted and drilled design
• Corrosion resistance to prevent rust buildup and extend rotor life
• Maintaining proper rotor thickness for consistent braking response

Installation Notes and Tips

Ensure the rotor surface is clean and free of any protective coatings before installation. Verify the bolt hole pattern and rotor dimensions match your vehicle specifications. It is recommended to replace brake pads when installing new rotors to optimize braking performance. Follow manufacturer torque specifications for lug nuts to avoid rotor warping. Proper bedding-in of the brake pads and rotors will help achieve optimal braking efficiency.
