Installation Notes and Tips

Confirm rear axle fitment against the vehicle’s brake configuration before installation, especially on models listed with vented rotor notes. Match the rotor to the correct Lexus GS350, IS350, or RC application by year and position, and inspect pads, caliper hardware, and hub condition during brake service.
