- All QuietCast rotors are factory mill precision balanced, which disperses the weight evenly, and allows for smooth, safe stops with no pedal pulsation
- Performance ensured by OEM style vane configuration that provides more efficient heat dissipation, reduced vibration for quieter operation, and extended rotor life
- Aluminum/Zinc coating protection prevents rust and corrosion, extending the life of the rotor while providing a clean look for today’s open wheels
- OEM style ABS tone ring (on required applications) provides trouble free operation of Antilock Brake and Traction Control systems
- Every Bosch QuietCast rotor features an engraved discard thickness, that lets you know when the rotor has reached its useful life, and an “on-the-part” Bosch brand name, so you can be confident you are receiving an authentic Bosch product
- FRONT: 319.8; Compatible with select vehicles (Note: vehicle trim level/engine may affect fitment – verify specific vehicle fitment details with fit checker above): MAZDA: 2007-15 CX-9

Match these baby up with Bosch pads and my Mazda CX9 stops in a dime. Love the galvanize coating on it, It keeps the rust out. Very solid no issue to install on a Mazda. It does not come with the hold screw, but if you have one you can reuse it, but I did not need it.
Just make sure to get some brake cleaner and spray them down before installing the calipers back on.

Installed these on our Mazda CX-9 three weeks ago. Our wheels are COVERED in brake dust and when we bring the car to a complete stop we hear the same high pitched squealing you hear when the brakes are bad and the wear plate hits the rotors. Bosch is synonymous with quality European made auto parts but these pads suck. The brake well but are noisy and we’ll never have clean wheels again

I recently put new rear rotors and pads on my daily driver. I got the best Advance Auto had to offer. They’re fine, no complaints.
But even more recently when I needed new front rotors and pads, I researched these Bosch Quiet Cast, with the clear rust resistant coating on the rotors, found them on Amazon, and discovered they cost less than the best from the auto parts store.
I have to say, the appearance of these rotors is hands down better than the others, and after a month of very rainy weather exposure, there’s no sign of rust yet. These combined with the Quiet Cast pads are fantastic. I’ve noticed no difference in noise, brake feel, or stopping power over the factory Ford parts they replaced, and the wheels are staying free of brake dust.
From now on, I’ll only get Bosch Quiet Cast.

These are some of the best Rotors I’ve ever used. I had some AC Delco on previously and made seem to get warm in a matter of thirty thousand miles. You seem very quiet and have held up very well. I would definitely recommend this to anyone.

These worked great with my Mazda CX-9, i paired them with Akebono ACT1258/9 ProACT Ultra-Premium Ceramic Brake Pad Set. Much better that original. To be honest i can’t tell if its the rotors or pads or the combination, but it works great.

Nice Fit, worked great, no issues. Sold the car a year later (regret it) but everything was working fine.
