BOSCH 34010890 QuietCast Premium Disc Brake Rotor - Compatible With Select Mazda 3, 5; FRONT; 1 PACK

half the price of OEM brakes and better quality, one rotor was incorrectly packaged, did not discover it until mechanic opened the box :(

Want to say my breaking is better. Not sure if it’s because of new rotor or the new rotor is better but definitely works very well.

I was doubtful that the aluminized coating on these rotors was going to last more than a few miles but it is holding up reasonably well after a couple of thousand miles on the front. What it really does is keep the radial ventilation holes from rusting and throwing them out of balance. The iron quality and casting seem high along with the grinding. These rotors have been quite and improvement over the OEM rotors. When it comes time to replace the rears, I'll use this same product.

So far so good, bought these for front and rear along with QuietCast rotors and they still look good after a 4 days of driving. It's rained, I've taken the car through the carwash and no signs of rust yet. They sure are quiet and equal to OEM brakes. I read some people having fitment issues and that's on them for not doing their research, Amazons fitment guide isn't always accurate. If you're looking at buying these or any car parts on Amazon I would do your research first for the part number specific to your car then search it on here.

Defected rotors, my steering wheels shakes when I use brakes,still didn’t hear anything from seller.

OK

I purchased these a couple weeks ago and installed on my wife’s car to replace some OEM warped rotors. Perfect fit on a 2011 2.5 GT and solved the vibration problem. No need to turn the new rotors or have them balanced, perfect right out of the box. Completely quiet and solid/straight braking. I used the OEM pads with about 36K miles on them and didn’t have to compress the calipers.

Nice rotors. Cheaper than OEM. Combined with Bosch pads they are excellent value for the money!

Kind of disappointed in these brakes. Bought them for my 2010 Mazda 5, both front and rear. The front right brake makes a terrible rubbing noise at low speeds and the hotter the brake gets the worse the noise. Had them professionally installed at a dealership and had to take it back. They proceeded to take the brakes apart on the front, twice, to determine what the problem was. They had to consult further with their senior technicians as there was no problem with the install. Conclusion by the dealership is that the brake rotor was a "bad cut". Thankfully they did not charge me for diagnosing the noise issue considering the work they had put in. Not sure yet if I will be able to get a replacement rotor. The dealership stated that there is a 50/50 chance that the noise will go away with wear.

Great quality product

Excellent!!
