Magura Venti's 203mm on BB7's
The Avid rotors would ting at speed and it was slightly annoying. These suckers are thick and beefy at the center as they cover the entire hub mounting area.

rotor is 2mm thick and goodbye ting-a-ling

mounts up and fits fine. plug and play

stops on a dime and you can get some nice controlled skids on the 203's.
