I'm trying to locate a few upgraded parts for my 99 SL500, namely some OEM size cross-drilled rotors and performance pads. I've tried a few on the web, but some don't seem all that MB oriented or are non-responsive when I inquire about the parts they have listed. Does anyone have a reliable parts company that they'd recommend? I'm in Atlanta so anyone local would be really appreciated. Ideally, I'd like to order from an MB specialist and have the parts shipped so I can have them installed.
