Detailed Product Description

This Dynamite Friction rotor features a vented design that helps reduce heat buildup during braking, which is critical for maintaining brake performance and preventing warping. The drilled and slotted surface improves water and debris evacuation, enhancing brake pad contact and reducing fade under demanding conditions. The rotor’s plain disc finish combined with a Geospec silver grey hat finish provides corrosion resistance, supported further by a rust-resistant coating to extend rotor life.

With a bolt hole pattern of 5 holes on a 112 mm circle and a center hole diameter of 65 mm, this rotor is specifically designed to fit a range of Audi and Volkswagen vehicles, including the Audi A3, Volkswagen Beetle, Bora, Caddy, e-Golf, Golf SportWagen, Jetta, Jetta City, Q2, and Taos. The directional surface ensures the rotor is installed correctly for optimal performance.

Applications and Problem Solving

• Reduces brake fade caused by overheating during extended braking
• Improves braking performance in wet or debris-prone environments
• Prevents rotor warping and uneven wear
• Enhances stopping power for daily driving and light performance use
• Compatible replacement for worn or damaged rotors on specified Audi and Volkswagen models

Installation Notes and Tips

Ensure the rotor is installed with the directional surface facing the correct rotation direction as indicated. Verify bolt hole alignment with the vehicle’s hub using the 5-bolt, 112 mm bolt circle pattern. Check rotor thickness before installation; replace if below the discard thickness of 22 mm. Clean the rotor surface to remove any protective coatings before mounting brake pads.

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.
