Hey guys, Ive been gather some info for my upcoming 350Z track rotor brake upgrade and was wondering if anyone had ordered the 350Z track rotor kit from Concept Z? If so, what were your opinions on the rotors he ships? Also, is it worth the extra 2 or 3 hundred to get the stoptech 350Z rotor kit he offers or are these overkill for my daily street driving and occasional canyon run? thanks for your help.
