hello, my friend has been having trouble with front brake rotors warping. I've been told by several mechanics (and suppliers) the chinese parts are the source of this problem. not all manufacturers but too many get rotors made in china. the result is cheap quality rotors that warp easy (less than 10k miles).
So, what is a good quality rotor that is in fact NOT made in china?
I'm thinking of either asking for original mercedes rotors or looking for very high quality after-market rotors (high performance). Does anyone know what AMG uses for brakes? I was wondering about upgrading and getting the better quality brakes AMG uses, but don't know too much about this.
I saw R1 concepts on ebay doing a search for 500 sel brake rotors. Are these any good??
Thank you
