xBosch QuietCast Premium Rear Brake Rotor — smooth, reliable braking you can trust
Crafted for drivers who value consistent performance and quiet operation, the Bosch QuietCast rear rotor pairs precision manufacturing with advanced materials. Its factory mill precision balance helps distribute weight evenly, contributing to smooth, pulsation-free stops and a calm pedal feel even during busy commutes or steep descents. This rotor is designed to work with the vehicle systems you rely on, so everyday braking can feel more predictable and controlled.
Heat management is at the heart of the QuietCast design. OEM-style vane configurations guide heat away from the braking surface, helping to maintain performance under repeated stops and reducing the likelihood of brake fade. The result is a braking experience that remains steady as you navigate city traffic, mountain roads, or long highway drives, without excessive noise or vibration.
- Balanced mill-precision rotor ensures even weight distribution for smooth, predictable braking.
- OEM vane layout enhances heat dissipation, reduces vibration, and can extend rotor life.
- Aluminum/Zinc coating protects against rust and corrosion, keeping the rotor looking clean on today’s open-wheel setups.
- OEM-style ABS tone ring on required applications supports reliable Antilock Brake and Traction Control interactions.
- Engraved discard thickness indicates remaining useful life, with Bosch branding to verify authenticity.
Rear-specific fitment for this model year range includes a 309mm rotor diameter. Compatibility spans select Lexus and Toyota vehicles, with trim and engine variation potentially affecting fitment. Use the fit checker above to verify exact compatibility with your configuration.
