I had the R1 Rotors on my Charger before I sold it a couple of weeks ago. I was very happy with them. Had them for about 2 years and had little to no wear. I was also running the Hawk Ceramic pads. The combo worked great. I installed Hawk Ceramics on my Camaro and Challenger as well. Very pleased with them. If I were to get the R1 Rotors for my Camaro or Challenger I would opt for the Slotted only rotors as the drilled ones make me nervous lol. Great Rotors though and the customer service was great.
