• Slotted design helps remove water, dust, and debris from the brake pad surface, maintaining consistent contact and stopping power.
• Vented construction enhances airflow around the rotor, further aiding in heat management and reducing thermal stress.
• Designed as a direct replacement for the factory rotor, ensuring perfect fitment and easy installation without modifications.
• Manufactured with strict quality control standards to meet or exceed OEM specifications, providing reliable performance and safety.
• Finished with a corrosion-resistant coating to maintain appearance and prevent rust, especially in harsh environments.
• Ideal for street driving, spirited driving, and light track use, offering a balance of performance, longevity, and value.
• Compatible with Lexus LS460 models equipped with standard or upgraded brake systems for enhanced stopping power.

Construction & Design

The PowerStop JBR1378XR rotor features a robust cast iron construction with precision-drilled and slotted patterns that are engineered for optimal heat dissipation and debris removal. The drilled holes are strategically placed to maximize airflow and cooling, reducing the risk of brake fade during intense braking. The slots help keep the brake pad surface clean, ensuring consistent friction and reducing uneven wear.

The rotor's vented design allows air to circulate freely between the two friction surfaces, further aiding in temperature control. Its corrosion-resistant coating protects against rust and corrosion, maintaining both performance and appearance over time. The manufacturing process adheres to strict quality standards, including TIG welding and CNC machining, to ensure precise fitment and reliable operation.

Performance & Sound

The PowerStop Evolution drilled and slotted rotor provides improved braking response and reduced stopping distances compared to standard rotors. The enhanced heat dissipation minimizes brake fade during repeated or aggressive braking, giving you confidence in your vehicle's stopping power. The design also helps reduce brake noise and vibration, resulting in a smoother, quieter braking experience.

Installation & Fitment

This rotor is a direct bolt-on replacement for the original equipment, requiring no modifications, cutting, or special tools. It mounts using the factory hardware and aligns perfectly with your Lexus LS460's brake calipers and pads. For optimal performance, it is recommended to inspect and replace brake pads simultaneously. No additional tuning or adjustments are necessary, making installation straightforward for experienced DIY enthusiasts or professional mechanics.
