The Dynamite Friction DFC GEOSPEC Coated Rotor - Drilled and Slotted (part number 634-63101) is engineered for precision braking performance. Designed specifically for Mercedes-Benz models such as the CLA45 AMG, GLA45 AMG, SLC43 AMG, and SLK55 AMG, this vented disc brake rotor offers reliable heat dissipation and consistent stopping power.
- Vented rotor design for improved heat management
- Drilled and slotted surface to reduce brake fade and improve water dispersion
- Nominal thickness of 22 mm with a discard thickness of 20 mm
- Outside diameter of 330 mm and inside diameter of 67 mm
- Five bolt holes with a diameter of 15.2 mm for secure fitment
- Height of 41.8 mm ensuring proper alignment and compatibility
Detailed Product Features and Specifications
This disc brake rotor is constructed with a vented design that enhances airflow between the rotor surfaces, helping to dissipate heat generated during braking. The drilled and slotted pattern on the rotor surface aids in reducing brake fade by allowing gases and debris to escape, which is especially beneficial during aggressive driving or in wet conditions. The rotor’s nominal thickness is 22 mm, with a discard thickness of 20 mm, indicating when replacement is necessary to maintain braking efficiency and safety.
With an outside diameter of 330 mm and an inside diameter of 67 mm, this rotor fits securely on compatible Mercedes-Benz models. The five bolt holes, each measuring 15.2 mm in diameter, ensure a precise and stable mounting. The rotor height of 41.8 mm is designed to maintain proper caliper clearance and brake system alignment.
