So, heat? Nothing has changed that would cause heat buildup. The car sits on AMG 2002-2004 style split-spoke wheels, which get PLENTY of air. There is no obstruction in either brake vent at the front of the wheel wells.

What can be done? I'm tempted to call the parts counter and find out if they're selling knock-offs.
