I bought these thinking it's ACDelco so it must be a good replacement for my '99 Suburban. What I didn't realize is that the Advantage ACDelco parts are a cheaper line of their parts as opposed to their Professional line. These cheap rotors introduced a vibration at highway speeds that took me a long time to track down. My wife was the primary driver for the Suburban so I didn't realize the vibration was introduced until much later and by that time I didn't correlate it to adding the rotors. Long story short, these rotors were warped from day one and caused nothing but heartburn. My suggestion would be to by the ACDelco Professional rotors instead. Even at that, I put the rear of my Suburban on jack stands so that I could observe the rotors turning to see if they were out of round and ended up sending one of them back because it came warped. Most people will tell you that you will only feel a brake rotor vibration when braking but I'm here to tell you that if you have rear drum rotors that are warped badly enough they can cause terrible vibrations while cruising at highway speed.

I use to only by ACDelco brand for my Suburban, but not any more. I purchased two of these. They came in different boxes, both made in china. The castings were different and the finishing grind on the inside was different. The vehicle pulled severely to the right for 5 to 7 days until the drums smoothed out. I get a high speed out of balance shake from the rear that I did not have just prior to the installation, so I'm guessing at least one of these were not balanced right. Looks like I will have to go down to the local Auto supply and replace these with a matching set. So sad to see that ACDelco has lost their pride and has opened their business to the lowest bidder.
