Raybestos R-Line Product Line Overview

The R-Line by Raybestos is a product line focused on delivering reliable braking components that meet or exceed OEM specifications. This line emphasizes quality materials and manufacturing processes to provide rotors that maintain structural integrity and consistent braking performance. The 980486R rotor is part of this line, offering a balance of durability and fitment precision for Lexus vehicles.

Detailed Product Description and Specifications

This Raybestos R-Line disc brake rotor features a vented design that enhances cooling by allowing air to flow between the rotor surfaces, reducing the risk of brake fade during extended use. The rotor's overall height measures 1.996 inches (50.7 mm), ensuring compatibility with the brake caliper assembly of the Lexus GS300 and IS250. The nominal thickness of 1.260 inches (32.0 mm) provides a solid braking surface, while the discard thickness of 1.181 inches (30.0 mm) indicates when the rotor should be replaced to maintain safe braking performance. The rotor includes five mounting bolt holes with a 0.573 inch (14.55 mm) diameter, arranged on a 4.5 inch (114.3 mm) bolt circle, matching the factory specifications for these Lexus models. The center hole diameter of 2.441 inches (62.0 mm) ensures proper hub fitment and alignment.

Applications and Problem Solving

• Replacement for worn or warped rotors on Lexus GS300 and IS250
• Addresses brake noise and vibration caused by uneven rotor surfaces
• Improves heat dissipation to reduce brake fade during heavy braking
• Restores proper rotor thickness for consistent braking performance
• Compatible with conventional brake systems requiring vented rotors

Installation Notes and Tips

Ensure the rotor surface and hub mounting area are clean and free of rust or debris before installation. Verify the rotor thickness is within specifications before mounting. Use proper torque settings on the mounting bolts to avoid rotor warping. It is recommended to replace brake pads simultaneously to ensure optimal braking performance. Check for any signs of uneven wear or damage on the caliper and hardware during installation.
