Great product!
I would most definitely buy these rotors again. They were a breeze to install on my 04 regal LS and they are wearing well after 2000 miles. Big Thumbs up to AC Delco!

2004 Chevy Impala
I purchased these to put on the rear of my 2004 Chevy Impala. Quality is excellent. It's been a year since I put them on and have had zero issues. Excellent braking performance, and they have held up well to winter + salted roads very well.

Incorrect Machining on mounting bracket
Caliper Bracket dos not fit, manufactured wrong. The cut out recess where the bracket mounts are too deep causing the bracket to wedge against the rotor and rotor will not move. Can clearly see the issue when compared to the old one. I had to use the old brackets.

They were an exact fit for the 2005 Impala and now it stops on a dime. 👍
