• Non-directional brake surface for versatile installation

Technical Details and Construction

The DuraGo BR31172-01 rotor features a full cast iron construction, providing a solid and durable braking surface. Its vented design allows air to flow between the rotor faces, helping to dissipate heat generated during braking. This reduces the risk of brake fade and maintains consistent performance under demanding conditions. The rotor's rust-resistant coating helps prevent corrosion, which is especially beneficial in humid or wet environments. With an overall height of 2 inches (50.8 mm) and a center hole diameter of 2.44 inches (62.1 mm), this rotor is engineered to meet the precise specifications required for Lexus GS300, GS400, GS430, IS300, LS400, SC300, SC400, and SC430 models.

Compatible Lexus Models and Applications

• Designed specifically for Lexus GS300, GS400, and GS430
• Compatible with Lexus IS300 and LS400 brake systems
• Fits Lexus SC300, SC400, and SC430 models requiring a 5-bolt vented rotor
• Ideal for replacing worn or damaged rotors to restore braking efficiency
• Suitable for vehicles requiring a conventional, non-directional rotor design

Installation Notes and Tips

• Ensure rotor thickness is above discard thickness (1.18 inches) before installation
• Check compatibility with vehicle ABS systems; this rotor does not include an ABS tone ring
• Use proper torque specifications for the 5 mounting bolts with 0.58 inch (14.8 mm) diameter holes
• Inspect brake pads and calipers during rotor replacement for optimal performance
• Clean rotor surface before installation to remove any protective coatings or debris
