I need new rotors and want to buy the parts on Amazon and then have a mechanic put them on. I searched all over and different size rotors seem to fit the model. Then I measured myself with the wheels still on, the front brake rotor seemed much larger, but since my wheels were still mounted it was tough to tell how accurate my measurements were.

I have a 2008 Mazda 3, 2.3L engine. The wheels are 16 inches (tires are 205-55r-16). is what I was looking at. I wouldn't mind spending a little more for the Cryo ones on the front if someone could point them out to me.

Are the front and rear the same size? And if not, what size are they? Amazon showed that 11 and 10.5 both fit.

Sorry for the wall of text, just hoping to solve my confusion. Thanks in advance!

 

I can't resolve all of your confusion, but front and rear are much different.

Look it up on a website of any auto parts store and RockAuto.com.

Typically you get what you pay for. Some rotors have walls so thin, they seem to warp when you touch them.
