well i installed my ceramics last night...and o man are these soooooooooooo nice..the grab really good. but i am sure that i will need to replace my rear calipers soon..so i'm thinking of changing them in a month when i replace all my rotors with brembo blanks...jess you were talking about upgrading to 6th parts...how hard is it to upgrade to 6th gen calipers and retain all other maxima parts? or am i suppose to upgrade pads also or can i keep my just installed ceramics?
