So far, the feedback from my brake pedal says it is giving me better than OEM stopping power. The calipers are as pretty as they are online, and the warranty that comes with it is the best I've seen. I am always skeptical when things do not cost a lot (considering that an OEM rear caliper is $150+ each), but being a college student, I had to give this a try... So far, seems like it was a great decision, and I will definitely be shopping here for parts in the future.
