I also get a clunking noise from front right wheel when I turn slowly like coming into the driveway. It is not consistant. seems to depend how much steering lock is applied. Not sure if it is all related. I just fitted new struts and shocks (Bilstein). Brakes (Irotor- centric with stoptech pads) and yes I fell for the slotted drilled look. I cannot see that these rotors could be warped and the theory of brake dust build seems a remote possibility.
