50011501 QuietCast Premium Disc Brake Rotor - Rear, 309mm (Single) | Compatible with Select Lexus RX350, RX450h; Toyota Highlander, Sienna

They're brake rotors, pretty straightforward. It's been 4 months since I installed them with Bosch pads on a '16 Toyota Highlander and no complaints. They're holding up exceptionally well in the Ohio winter - no signs of rust even with my bad habit of not washing the salt off regularly. The rotors and pads are silent; no vibration; great coating that inhibits rust. I'll update the review if anything changes for the worse in the future.

Fits just right, same diameter as original REAR brake discs, they come coated so they don’t rust and there’s no oily residue to clean before installing them. Paired with some bosch ceramic brake pads and these are quiet as a mouse.🐁 I would buy again and recommend them.

These have been great. I have put 10,000 miles or more on them already and they have held up. I'm definitely going to order some for the front when replacing those rotors.

First time using Bosch rotors. Used the Bosch parts in my old BMW before. These rotors were for my 2015 Sienna SE. The van developed pulsation while applying brakes at higher speed. I chose Toyota brake pads and Bosch rotors. Great fit. Easy install. Problem solved. Thinking of the same combo for the front to completely renew my brakes.

First of all I want to say, if you are on the fence about rotors. PLEASE avoid the company Detroit Axle at all cost I played myself by trying to save $20 and I still haven't gotten my refund! On the other hand I purchased the same set of Bosch for the front over a year ago and have had no complaints. I used raybestos pads, good quality for the price.

I put these on a 2015 Sienna with pads from the Toyota dealership. They work great, quiet and even. My only complaint is that the inside diameter is a little larger than the ones sold from Toyota so my parking brake no longer engages completely. It’s not something we use often so not a huge issue but consider adjusting the parking break when you install them.

I just pulled these off my 2011 Sienna XLE. I installed them in 2017 so they made it about 4 years and I would guess about 30-40k miles. We have had a vibration within 6 months of installing them, it got progressively worse the entire time. I did a proper bedding procedure. I actually assumed it was the front where I put on a value set of rotors and pads from advanced auto the weekend after I installed these. Well the pads wore out to the wear indicators so I replaced them. These were the cause of all the issues, not the cheap front set which is still going strong. The vibration is completely gone. I am a huge fan of bosch stuff but I will avoid the rotors & pads going forward.

Fits my Toyota and works well. Bosch brand at a good price. Good alternative to OEM

Did fit easily

Good quality

I tried many different brands but i stick to these now for all the cars.

whistle noise, when you slowly press the breaks, defective item
