A-Premium Drilled & Slotted Rear Brake Rotors — F10 5 Series

The rotors are cast from G3000 metallurgy, the same high-carbon iron specification used by many OE brake suppliers, delivering consistent thermal stability and wear resistance over the long haul. A factory-applied metallic coating guards the rotor face and hat against corrosion during storage and between brake pad contact zones, so you're not fighting rust-jacking on a rotor you just installed. Tight runout and DTV (disc thickness variation) tolerances are maintained from the factory, which directly translates to a smooth, judder-free pedal feel from the first drive.

The cross-drilled holes and machined slots aren't just aesthetic — they serve distinct functional roles. Drilling reduces rotor mass and provides escape channels for heat and outgassed material produced during repeated hard stops, while the slots continuously sweep the pad face clean of debris and glaze, maintaining a fresh bite surface. Together, they keep brake temperatures lower and pad contact more consistent, resulting in shorter stopping distances and reduced fade during spirited driving or repeated deceleration events on longer descents.

Each purchase includes two rotors — driver and passenger side — making this a complete rear axle replacement in a single order. A-Premium backs the set with a one-year unlimited-mileage guarantee, which is a meaningful commitment for a budget-tier rotor and gives you a genuine fallback if a manufacturing defect surfaces. Reference numbers S-1213413 / S1213413 can be used to cross-check compatibility with your parts catalog or confirm a match with your independent shop before installation.
