The high-carbon casting supports better thermal transfer, while the coated finish helps resist corrosion on exposed surfaces. This rotor is identified by part number 150.3465.32 and is intended for BMW front brake applications listed in the fitment data, including 2008-2013 BMW 135i front and 2013 BMW 135is front. It also fits 2012 BMW 120i front with Performance Brake equipment.\u003c\/p\u003e\u003ch2\u003eCommon Issues Addressed\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eBrake pulsation from worn or uneven rotor surfaces\u003c\/li\u003e\n\u003cli\u003eReduced braking consistency during repeated stops\u003c\/li\u003e\n\u003cli\u003eCorrosion on exposed rotor surfaces\u003c\/li\u003e\n\u003cli\u003eRotor wear that has reached minimum thickness\u003c\/li\u003e\n\u003cli\u003eHeat buildup in demanding driving conditions\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes\u003c\/h2\u003e\u003cp\u003eVerify rotor diameter, hub bore, bolt pattern, and brake system configuration before installation.
