I found a place, www.buybrakes.com, which has Rotex brake pads for a lower
price than brakeworld, though lower doesn't always equal available I guess.

I ordered the Rotex MBz part numbers since they didn't have a listing on their site for
the Crossfire. They sent me an email to clarify my order and I let them know the
pads are for a Crossfire. They said no problem, but that they were out of
the front Rotex pads, I had ordered front and rear. The Axxis pads cost a little
more, but they are willing to send the Axxis pads for the same price as the Rotex.

Looking up Axxis Delux Plus on google, I see that they are performance pads
and popular on BWM's. The few places I looked, no one seemed to be negative.

Anyone on this forum have any experience with Axxis pads on the Crossfire
or other cars?
