Got some Powerstop pads and rotors for my Kia Stinger, pads had been done before I bought it but rotors were terribly warped.

1. Realized I put them on backwards after I took this picture, slots have a specific orientation.

2. Rear rotors are a pain on modern cars with electronic parking brakes because those are actuated by drum brakes under the rear rotors. There is something on the back of the new rotors rubbing against against the drum brakes, it made a terrible sound when I first put them on but I took it to a tire shop and they said it would go away with time, just drive the car and it will wear itself down with time.
