Ok so my suspicions have been verified My rotors are not only out of spec but one has a slight warp. my Mechanic said ride it till it annoys me then replace both. Great Idea except It annoys me now. Question is EBC for $202 a side or $280 (Ron Ayers) for OEM . Using stock pads which would void EBC warranty. My friend Loves the EBC on his connie does anyone here have any experience on the ST1300A
