I've had them on my Dodge Charger R/T AWD 07 for over a month now. They're working great so far! Great stopping power. Remember this is for the police pack. Which tail rotors are more than OEM. I wanted bigger rotors because the smaller ones from other brands always warp easily. I went to the dealer and bought a large caliper brace so I could mount these rotors. As I said, so far so good. I'm really happy at the moment. Should anything fail or the rotors deform quickly I will update this review.
