If you guys really care about the quality of your brakes, why not go to a place like German Autoparts.com and buy the quality rotors they sell there. Here's a link to rotors for a 2004 SLK320.

I just bought a set of blank brembo rotors for my VW from the parts bin. Here's the link to rotors for a 2007 crossfire:
Parts Bin - Auto Parts and Accessories Catalog - 2007 Chrysler Crossfire Brake Disc
Disc italia? I never heard of them before I came to this site. Why cheap out on brake rotors? Both places I have linked to sell high quality rotors. I've bought from both places in past and will continue to do the same in the future. Some the places in this thread seem shadey as all get out! :-)
