My 09 Sonata needs a brake job and I like to do them myself. I have some minor pulsing of the front rotors so I would prefer to replace them rather than hassling around with getting them turned. The auto parts store sells a premium rotor that is flat to within 0.004 inches and a super premium rotor which is flat to within 0.002 inches for twice the price. My first question is this: which one meets the sonata spec for required runout? Second question is this: Are the original brake pads organic semi-metallic or ceramic?
