Raybestos R-Line Product Line Details

The R-Line by Raybestos focuses on delivering dependable brake components that meet or exceed OEM specifications. This product line emphasizes precise engineering and quality materials, making the 9173R rotor a suitable replacement part for Toyota Celica owners seeking consistent braking performance and durability.

Technical Description and Specifications

The 9173R disc brake rotor features a vented design that enhances heat dissipation during braking, reducing the risk of brake fade under normal driving conditions. With an overall height of 1.820 inches and an outside diameter of 9.370 inches, this rotor fits Toyota Celica models requiring a 4-bolt mounting pattern with a 3.937 inch bolt circle diameter. The nominal thickness of 0.865 inches ensures structural integrity, while the discard thickness of 0.787 inches indicates the minimum safe thickness before replacement is necessary. The center hole diameter of 2.126 inches allows for proper hub fitment, and the rotor is designed as a conventional type rather than drum-in-hat style.

Applications and Problem Solving

• Replacement for worn or warped rotors on Toyota Celica
