With an outside diameter of 11.591 inches and a nominal thickness of 0.980 inches, this rotor fits precisely to ensure proper brake pad contact and rotor longevity. The vented design helps dissipate heat generated during braking, reducing the risk of brake fade under normal driving conditions. Featuring five mounting bolt holes arranged on a 4.5 inch bolt circle diameter, this rotor is engineered for straightforward installation on compatible Mazda models. The discard thickness of 0.910 inches indicates the minimum safe thickness before replacement is necessary, helping maintain braking safety and performance.\u003c\/p\u003e\u003ch2\u003eAbout the Raybestos R-Line Product Line\u003c\/h2\u003e\u003cp\u003eThe R-Line by Raybestos is a product line focused on delivering reliable, OEM-quality brake components designed to meet or exceed factory specifications.
