I got mine today and just installed (BIG thanks to Jeff McKenzie for last minute install) they are an unbelievable upgrade to the hawk HP +. Just got back from bedding them in...thank god I got home safely, I felt like an idiot bedding them in, I think I did the job though.
Mine are quite new; otherwise, I'd pick 'em up. Beware - these are serious pads. They are dirty, and they are noisy (relative to street pads). They will, without question, stop your car. Go to the Carbotech site for info bedding info. They are a different compound from most street pads.
