Verify rear axle fitment, brake package, and any model-specific notes before ordering. This kit is listed for standard brake applications only, and the 2015 BMW 328i rear fitment requires the 194mm rear disc hat diameter note shown in the catalog data. Follow BMW service procedures for rotor and pad replacement, and inspect caliper condition, slide hardware, and brake fluid condition during service.
