Just got my 2011 XB and have been reseaching for the door step sills. The door sills and bumper protector combo from Ebay looks good but might want something more subtle. Does anyone here get Scion xB Spec-D Tuning Door Step Sill before? They are made of carbon. What are your opinions with regard to their durability, look, ease of application? Do they fit the door step well?
