Product Line Details: Centric Premium High Carbon Alloy Disc Brake Rotors

The Centric Premium High Carbon Alloy Disc Brake Rotors line focuses on high carbon alloy construction to enhance rotor strength and thermal stability. This product line is designed to reduce brake fade and extend rotor life, making it suitable for performance-oriented vehicles like the BMW 750Li and Mercedes-Benz 550i GT xDrive. The high carbon content also helps minimize noise and vibration during braking.

Technical Specifications and Features

This disc brake rotor features a vented design that improves heat dissipation during braking, reducing the risk of warping under heavy use. The coated hat finish provides corrosion resistance, extending the rotor’s service life. With a nominal thickness of 36 mm and a discard thickness of 34 mm, this rotor maintains structural integrity while meeting safety standards. The rotor’s overall diameter measures 374 mm, compatible with specific BMW and Mercedes-Benz models requiring a 5-lug bolt pattern with a 120 mm bolt circle diameter. The floating mounting type allows for slight movement to accommodate thermal expansion and improve braking consistency.

Compatible Vehicles and Applications

• BMW 550i GT and 550i GT xDrive
• BMW 750i, 750i xDrive, 750Li, and 750Li xDrive
• Mercedes-Benz SLK55 AMG

This rotor is designed for use in OEM replacement and maintenance scenarios where maintaining factory braking performance is critical.

Common Issues Addressed by This Rotor

• Brake rotor warping due to heat buildup
• Corrosion and rust on rotor surfaces
• Uneven brake pad wear caused by rotor surface irregularities
• Brake noise and vibration during stopping
• Reduced braking efficiency from worn or undersized rotors

Installation Notes and Tips

Ensure the rotor is installed on compatible BMW or Mercedes-Benz models listed above. Verify the bolt hole pattern matches the vehicle’s hub assembly (5 lug, 120 mm bolt circle). Clean the rotor surface before installation to remove any protective coatings or contaminants. Use proper torque specifications for mounting bolts to avoid rotor distortion. It is recommended to replace brake pads simultaneously to ensure optimal braking performance.
