Product Line Details: Centric Premium Disc Brake Rotors

The Centric Premium Disc Brake Rotors line focuses on delivering rotors that meet or exceed OEM specifications. This product line emphasizes quality materials and precise manufacturing processes to provide rotors with consistent thickness and balanced venting. The 120.62090 rotor benefits from this approach, offering a vented design that helps maintain optimal braking temperatures and a coated hat finish that extends rotor life by reducing corrosion.

Technical Description and Specifications

This disc brake rotor features a vented design, which improves heat dissipation during braking, reducing the risk of brake fade. The rotor has a nominal thickness of 18 mm and a discard thickness of 16 mm, indicating when replacement is necessary to maintain safe braking performance. The outside diameter measures 285.7 mm, suitable for the braking system of the Pontiac GTO. The rotor includes five bolt holes arranged on a 120 mm bolt circle diameter, with a center hole diameter of 70.1 mm to ensure proper fitment. The smooth surface type provides consistent contact with brake pads, while the coated hat finish protects against rust and corrosion.

Common Applications and Problem Solving

• Replacement for worn or warped rotors on Pontiac GTO
