The nominal thickness of 25 mm ensures structural integrity, while the discard thickness of 23.4 mm indicates the minimum safe thickness before replacement is necessary. The rotor’s 325 mm outside diameter and 75 mm inside diameter are tailored to fit the BMW X3’s braking system precisely. With five bolt holes each measuring 16.6 mm in diameter, installation aligns with factory specifications. The rotor height of 62.3 mm supports proper caliper clearance and brake pad engagement.\u003c\/p\u003e\u003ch2\u003eDFC GEOSPEC Coated Rotor Product Line\u003c\/h2\u003e\u003cp\u003eThe DFC GEOSPEC Coated Rotor line by Dynamite Friction is designed to provide enhanced corrosion resistance and consistent braking performance. The coating helps protect the rotor surface from rust and environmental wear, extending the rotor’s service life.
