Ralj posted in another thread about his rotors going at 20-25k intervals (2002 S430) and has found a TBS that he graciously sent to me. However, it does not involve the 202. Nevertheless, my rotors are warped after 21k and the dealer says this is common, and not a warranty item? What the hell? I've never heard of pads outlasting rotors. If I have to pay for rotors, I am not inclined to buy expensive MB replacements. What do you like? Brembo cross-drilled? ATE? Greenstuff slotted?
