R1 13-19 Cadillac ATS Rear Left Drilled & Slotted Black Brake Rotor

This is the rear left brake rotor for your 2013-2019 Cadillac ATS. It's a drilled and slotted rotor with a black finish from R1 Concepts, designed to replace your factory original. These rotors help your brakes perform better, especially when you're stopping hard or driving in wet conditions.

The drilled holes in the rotor help to vent gases and heat away from the brake pad surface. This means you get more consistent stopping power and less chance of the brakes fading when they get hot. The slots on the rotor surface also help to sweep away dust and gas, keeping the pad surface clean and ready to grab. The black finish isn't just for looks; it helps protect the rotor from rust and corrosion, keeping it looking good and working well for longer.

This rotor is a direct replacement for the original on the rear left side of your ATS. Make sure to replace rotors in pairs (left and right) for balanced braking performance.
