Ask for Bosch QuietCast™ Premium Disc Brake Rotors at your local auto supply store or your wholesale supplier.
Full-line Domestic, Asian and European
All QuietCast rotors are factory mill precision balanced, which disperses the weight evenly and allows for smooth operation.
Industry low run-out and DTV specifications
Ensures smooth pedal feel and safe stops.
G3000 heat-flowed castings
Bosch QuietCast rotors use Heat-Flow G-3000 castings for Domestic and Asian applications which provide consistent wear, long life, and quiet operation.
On Euro applications, G3000, GG-20, GG15, and high carbon castings are used, following OEM for low NVH and superior performance.
OEM style vane configuration
OEM style vane configurations pull the heat from the inner part of the wheel, away from the caliper, speeding the cooling process and increasing performance and life. Using OEM vane techniques reduces the amount of heat absorbed by the wheel hub, which eliminates premature hub failures.
OEM style ABS tone ring (on required applications)
Trouble-free ABS/TCS operation
Factory engraved edge code
The on-the-part Bosch brand ensures quality and the discard thickness lets you know when the rotor has reached it useful life.
Premium clean look coating protection
Select applications of QuietCast rotors have a clear-look coating protection, which
- Prevents rust and corrosion
- Extends the life of the rotor
- Allows for better heat dissipation
- Provides a clean look for today’s open wheel applications.
Coated applications are salt spray tested to exceed 300 hours of corrosion free operation. This coating is water-based, environmentally friendly, and aluminum-zinc based.
Bosch is the only rotor manufacturer to conduct visual, dimensional and material inspections on brake rotors.

What is the best way to improve brake performance?
The best way to improve brake performance is to purchase high quality brake components such as Bosch QuietCastTM Premium Brake Pads and Bosch QuietCastTM Premium Disc Brake Rotors. Additionally, a thorough brake job that restores a vehicle’s brake system to its original operating condition can also improve a vehicle’s braking performance.
How often should my brake system be inspected?
A vehicle’s braking system should be checked as stated by the vehicle’s factory maintenence schedule.
Are slotted or drilled rotors better than non-slotted or non-drilled rotors?
In high performance vehicles, slotted or drilled rotors are an advantage due to additional high braking temperatures. Bosch QuietCast™ Premium Disc Brake Rotors are drilled and slotted in applications where the OE design specifies this requirement.

Where are Bosch QuietCast™ Premium Disc Brake Rotors manufactured?
Bosch QuietCast™ Premium Disc Brake Rotors are manufactured by the world’s leading brake rotor manufacturers. Bosch QuietCast™ coverage includes European, Domestic and Asian vehicles. Bosch’s European applications are sourced from European vendors, in order to keep the OE style form, fit and function. Bosch’s Domestic and Asian rotors are sourced from industry leading manufacturers in the Asian-Pacific region.
What causes rotor warping/runout?
Rotor warping/runout can be due to improper rotor installation during the tightening (torquing) of the lug nuts.
What are the benefits of coated rotors?
Premium coated rotors are designed to prolong corrosion and maintain higher thermo stability, allowing for extended brake system longevity.
Do coated rotors effect my braking performance?
No, the brake pad brushes off the coating on the rotor’s braking surface within the first 50 stops.
What is the best way to improve brake performance?
The best way to improve brake performance is to purchase high quality brake components such as Bosch QuietCastTM Premium Brake Pads and Bosch QuietCastTM Premium Disc Brake Rotors. Additionally, a thourough brake job that restores a vehicle’s brake system to its original operating compacity can also improve a vehicle’s braking performance.
Why should machined brake rotors be washed when installing new pads?
Machined rotors should be washed with a mild dishwashing detergent and hand brush prior to installing new brake pads. This process removes machining debris left on the surface of the rotor from the machining process. Failure to properly wash the machined rotors can result in damage to the friction material on the new pad and additional vibration and noise.
