can anyone tell me the approx. cost of the cross drilled rotors? and what advantages do they have and if i did get them could i have the dealer put them on for me or would they not do that. also, i think i need them because i constantly get that annoying noise coming from them , they are warped i think, i got them machined not long ago so i dont really know why the noise is still there. the last time they forgot to put a spacer back in my caliper and when they fixed that it was fine for a few weeks, but the noise is back. any suggestions? sorry for the long post
