I had them. Had brake squeaking so I took them off before I went to the dealer anticipating a problem because I had them on. I had them for probably 5000 miles. They work absolutely perfectly. The brakes (pads and rotors) turned out to be fine just packed with mud (see the mud thread).

I destroyed them getting them off as they had almost fused with the wheel.

I'm gonna reorder them but I'm not sure if I'm gonna get the flat black or the glossy black. I will defintetly be cleaning the inside occasionally on this next set.
