Bosch QuietCast Front Disc Brake Rotor 328mm (Single) – Premium OEM Fit, Corrosion-Resistant

BOSCH QuietCast 50011479 is a front, 328mm premium replacement disc brake rotor engineered to restore OEM braking feel, reduce noise and resist corrosion for compatible Lexus and Toyota models.

This single front rotor is built to meet or exceed factory expectations for fit, balance and longevity. Bosch designed the QuietCast line to combine precision machining, an OEM-style vane layout and a corrosion-resistant coating so the rotor performs smoothly on modern vehicles with open-wheel designs while maintaining compatibility with ABS/traction systems where required.

How does this rotor improve braking performance?

The QuietCast rotor offers factory mill balancing and an OEM-style internal vane configuration that together lower vibration and promote even pad contact. That translates into steadier pedal feel, fewer noise events and consistent stopping power under routine driving conditions.

• Precision-balanced at the factory to prevent pedal pulsation.
• Optimized vane layout for faster heat dispersion and reduced vibration.
• Engineered for even pad wear to help maintain braking consistency.

Will this rotor resist rust and keep a clean appearance?

Yes — Bosch applies an aluminum/zinc protective coating to help block corrosion on exposed surfaces. The finish preserves a cleaner look behind open wheels and helps the rotor last longer in climates where road salt and moisture accelerate rust.

• Aluminum/zinc coating shields against rust and surface corrosion.
• Clean visual finish for modern alloy wheel designs.
• Coating extends service life compared with untreated rotors.

Is this rotor compatible with ABS and traction control systems?

For applications that require ABS tone information, the QuietCast rotor includes an OEM-style tone ring to ensure proper communication with wheel-speed sensors. That makes the rotor suitable for vehicles equipped with ABS and electronic traction/stability systems without aftermarket modifications.

• OEM-style ABS tone ring provided on applicable fitments.
• Plug-and-play compatibility with vehicle sensor systems.
• Designed to maintain factory safety system performance.

Which vehicles will this Bosch rotor fit and what specifications should I verify?

This front rotor measures 328 mm and is listed for select Lexus and Toyota models, including NX, RX, Highlander and Sienna model years shown by Bosch. Because trim, axle configuration or engine options can change fitment, always confirm the rotor matches your vehicle’s year, model and front rotor size before purchase.

• Rotor diameter: 328 mm, front application (single unit).
• Common compatible vehicles: certain Lexus NX200t/NX300/NX300h, RX350/RX450h and Toyota Highlander, Sienna years as listed by Bosch.
