Raybestos R-Line Product Line Details

The R-Line by Raybestos focuses on delivering rotors that align closely with original equipment specifications. This product line emphasizes consistent thickness and precise mounting dimensions, such as the 4.720-inch bolt hole circle diameter, to ensure proper fit and function. The 980650R rotor exemplifies the R-Line’s commitment to quality and compatibility for BMW vehicles requiring conventional disc brake rotors.

Technical Specifications and Features

This disc brake rotor features a nominal thickness of 1.180 inches (29.950 mm), providing a solid braking surface for effective heat dissipation and wear resistance. The discard thickness is set at 1.120 inches (28.450 mm), indicating the minimum safe thickness before replacement is necessary. The mounting bolt hole circle diameter and bolt hole diameter both measure 4.720 inches (119.900 mm), ensuring a precise fit on compatible BMW brake assemblies. The rotor is designed as a conventional type, suitable for standard drum-in-hat brake systems.

Common Applications and Problem Solving

• Replacement for worn or warped rotors on BMW 335i and 335d models
• Restores braking performance affected by rotor thickness below discard limits
• Addresses vibration or noise issues caused by uneven rotor surfaces
• Ensures proper fitment for BMW X1 brake assemblies requiring 4.720-inch bolt circle diameter
• Supports safe braking by maintaining OEM thickness specifications

Installation Notes and Tips

When installing the Raybestos R-Line 980650R rotor, verify the rotor thickness before and after installation to ensure it meets the nominal thickness of 1.180 inches. Clean the mounting surface and bolts to prevent uneven rotor seating. Use proper torque specifications for the 4.720-inch bolt hole diameter to avoid warping. It is recommended to replace brake pads simultaneously to optimize braking performance.
