The Dynamite Friction DFC GEOSPEC Coated Rotor 604-74021 is engineered for reliable braking performance on select Audi and Volkswagen models. Designed as a vented disc brake rotor, it offers consistent heat dissipation and durability for vehicles like the Audi Golf, Jetta, TT, and TT Quattro.

• Nominal thickness of 25 mm with a discard thickness of 23 mm
• Vented rotor design for improved cooling
• Outside diameter measures 312 mm for precise fitment
• Five bolt holes with a diameter of 15.75 mm
• Inside diameter of 65 mm and rotor height of 34.2 mm

Detailed Product Features and Specifications

This disc brake rotor features a vented design that enhances airflow to reduce heat buildup during braking, which helps maintain consistent stopping power and rotor longevity. The nominal thickness of 25 mm ensures structural integrity, while the discard thickness of 23 mm indicates when replacement is necessary to maintain safe braking performance. The rotor’s 312 mm outside diameter and 65 mm inside diameter are tailored for compatibility with specific Audi and Volkswagen models, including the Golf, Jetta, TT, and TT Quattro. The five bolt holes, each 15.75 mm in diameter, provide secure mounting, and the rotor height of 34.2 mm supports proper caliper clearance and fitment.
