The C Street thread will either be enlightening or terrifying for you, take everything with a grain of salt:

I ended up buying a more street oriented pad because I'm cheap and wanted to see if I could get away with it so I got Project Mu NS400, pretty good street pad so far, won't know for awhile how they hold up to auox. Not sure what I'll do after that, W2/3, HC800 or DS2500 are top of the list followed by AX6. Hmm maybe I should just say fuck it and do the AX6's... Guess I'm just nervous how long they'll last DD as I don't want to buy pads every year. I really like my Carbotech XP10's for the track and they respond to autox very well but I can't get heat in them regularly enough for them to stay quiet on the street for more than a few days, the stock rotors are beastly, don't replace them thinking you've made an upgrade and when you do everyone seems to love the cheap centrics that you can get on Amazon prime.
