• Constructed from high carbon cast iron for enhanced strength and heat dissipation
• Features a rust-resistant Geomet coating to protect against corrosion
• Vented rotor design improves cooling and reduces brake fade
• Nominal thickness of 0.98 inches (24.90 mm) with discard thickness at 0.91 inches (23.00 mm)
• Overall height of 1.40 inches (34.30 mm) and outside diameter of 12.30 inches (311.60 mm)
• Mounting bolt hole circle diameter of 100 mm (3.90 inches) with 5 lug holes

Detailed Product Description

This Power Stop rotor is made from high carbon cast iron, which provides improved wear resistance and thermal conductivity compared to standard rotors. The vented design allows air to flow between the rotor surfaces, helping to dissipate heat generated during braking and reducing the risk of brake fade under demanding conditions. The Geomet coating applied to the rotor surface offers a protective barrier against rust and corrosion, extending the rotor's service life and maintaining consistent braking performance.

With precise dimensions including a nominal thickness of 0.98 inches and a discard thickness of 0.91 inches, this rotor meets strict OEM specifications. The 5-lug hole pattern with a 100 mm bolt circle diameter ensures proper fitment on compatible Audi and Volkswagen models, including the Golf, Jetta, TT, and TT Quattro.
