There are brake pads available for 2015+ STI's for $5CAD on rockauto. They are semi-metallic. I assume that the pad material on my (2ndhand) car right now is also semi-metallic as they are dusty and noisy. Who cares if the $5 pads wear out faster? Why pay over $100 for pads that might last longer when I can get these pads nearly for free? Random manufacturing defects aside, do you think these people could sell brake pads that that will fail?
