The rotors are machined to tight tolerances, inspected for critical dimensions, and finished to support even braking performance. The pads are formulated for consistent friction and assembled with shims that help reduce vibration and brake noise. This makes 4512-31249 a practical choice for a rear brake job on a BMW 328i where fitment, finish, and drivability matter.\u003c\/p\u003e\u003cp\u003eThis part cross-references Monroe Shocks \u0026amp; Struts (e.g., 172286, 182286) for the same application.\u003c\/p\u003e\u003ch2\u003eCommon Brake Issues It Can Address\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eBrake noise from worn rear pads or fatigued hardware\u003c\/li\u003e\n\u003cli\u003eUneven rear pad wear caused by corroded or stressed hardware\u003c\/li\u003e\n\u003cli\u003eRotor rust buildup on exposed braking surfaces\u003c\/li\u003e\n\u003cli\u003eReduced braking smoothness from worn or out-of-spec rear components\u003c\/li\u003e\n\u003cli\u003eExcessive caliper movement related to aged brake hardware\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes\u003c\/h2\u003e\u003cp\u003eConfirm rear fitment before installation: 2014-2015 BMW 328i, rear, with M Sports Package, single piston front calipers, and 330mm rear rotors. The rotors are processed dry and ready to install, which helps reduce prep time during service. Clean all mating surfaces, inspect caliper slides and mounting points, and follow the vehicle manufacturer’s brake service procedure for proper torque and bedding.\u003c\/p\u003e\u003ch2\u003eQuality Assurance\u003c\/h2\u003e\u003cp\u003eDFC states that each GEOSPEC rotor is inspected for critical attributes and that vented rotors are balance-corrected when needed. The rotors carry a 12-month warranty against defects in material and workmanship. The brake pads are post-cured and scorched to support stable friction performance from the initial stop.\u003c\/p\u003e","brand":"Dynamite Friction","offers":[{"title":"Default Title","offer_id":52467834486965,"sku":"HBHR-4512-31249","price":199.27,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0628\/1442\/1173\/files\/DF_451231249_Fro.jpg?v=1777952488","url":"https:\/\/www.partcatalog.com\/products\/dynamite-friction-4512-31249-disc-brake-kit-rear","provider":"PartCatalog","version":"1.0","type":"link"}
