As the title states, what is the size of the stock rotor for a '99 E430 Sport?
I'm having difficulty with Tirerack, and need to verify the proper rotor size. I'm getting two different opinions. Tirerack sent me 316mm Brembo replacement rotors, but my indy mechanic is telling me that I need 299ish mm fronts. Can someone point me in the right direction? Attached is the rotor in question. Thanks for any input or for pointing me in the right direction.
