What is the main benefit of drilled and slotted rotors over standard rotors?

Drilled and slotted rotors help improve brake performance by dissipating heat more effectively through the holes and clearing away gases, dust, and moisture with the slots. This leads to more consistent stopping power, especially during hard braking or repeated stops.

Do these rotors come with any hardware or are they sold as a pair?

These rotors are sold as a pair for the rear axle of your vehicle. Installation hardware is not typically included and may need to be sourced separately if your original hardware is worn or damaged.

How does the zinc plating help these rotors?

The silver zinc dichromate plating on these rotors provides protection against rust and corrosion. This helps maintain the rotor's appearance and prevents premature degradation, especially in areas exposed to moisture and road salt.

Product Details

If you're looking to get more out of your BMW's braking system, especially during spirited driving or when carrying extra weight, these Power Stop Evolution drilled and slotted rotors are a solid option. They're designed to replace your stock rear rotors directly, meaning no special modifications are needed for installation. The cross-drilled holes help dissipate heat, which is crucial for preventing brake fade when things get hot, while the rounded slots work to sweep away gases, dust, and moisture from the rotor surface. This keeps the pad in constant contact with a clean rotor face, ensuring consistent stopping power.

These rotors are built to strict tolerances for runout and DTV (disc thickness variation), which helps ensure smooth, quiet operation and prevents the kind of pulsing you can feel in the brake pedal with less well-made rotors. The silver zinc dichromate plating offers good protection against rust and corrosion, keeping your rotors looking good and functioning properly for longer. They match the original equipment design in terms of weight and vane count, so you know they're engineered to work with your BMW's existing brake system, including models like the 2013-2018 BMW 320i xDrive, 2014-2018 BMW 328d xDrive, and 2014-2016 BMW 328i GT xDrive.
