I am looking to change the factory pads on my 2007 Boxster to dustless. The factory pads work great but are the dirtiest pads I have had. 50 street miles and the wheels look as if I just got off the track. Wheels get dirty real fast and attract a lot of rail dust, which is hard to remove without using a claybar. I heard ceramic pads are an option. Any ideas? Pros, cons to the idea?
