I bought a pair of these drums for the back of my 2010 Toyota Corolla S as Revane said they were perfect for my car. So! Received the item from Amazon within a reasonable time. my mechanic installed the parts on 01/24/2014. Everything seemed fine until a few days ago I started hearing a loud rattle from the back of my car. Now I had to order a pair of genuine Toyota Corolla drums for my car to make the injury worse. I'm going through a return period. So my advice to others, stay away from this brand unless you want to buy precision machined parts. This is actually the second time I have had problems with their parts, the first was I bought a set of anti-roll bar bushings, installed them at the mechanic, same day after road testing the car that the car had over-engineered wobble, removed them and installed the Dorman stabilizer with bushing which corrected the problem. I compared their bushings to the ones Toyota sells for my car and found that the Rybestos bushing ID is much larger than the Dorman and Toyota ones. that the larger diameter allowed movement within the bushing. So, that's enough! Raybest no longer exists!
