Detailed Product Features and Specifications

This disc brake rotor features a vented design that improves airflow to reduce heat buildup during braking, which is critical for maintaining consistent stopping power. The drilled and slotted surface helps evacuate gases, dust, and water, enhancing brake pad contact and reducing brake fade. The rotor’s nominal thickness is 25 mm, with a discard thickness of 22 mm, ensuring a clear service limit for safety and performance. The hat section is finished in Geospec silver grey, providing corrosion resistance alongside the rust resistant coating applied to the rotor surface.

With 5 bolt holes spaced on a 112 mm bolt circle diameter and a center hole diameter of 65 mm, this rotor is designed to fit specific Audi and Volkswagen models including the A3, Beetle, Bora, Caddy, e-Golf, Golf, Golf SportWagen, Jetta, Jetta City, Q2, and Taos. The directional surface pattern is engineered to optimize braking efficiency and pad wear.
