Anyone know of a shop in the Bay Area (near SF preferrably) that has installed side gills on a E90 sedan specifically? I tried several times using several different DIY methods from the threads posted here with no luck. I didn't want to crack or chip my paint, so I didn't want to force anything. So I'd like to go to a shop that someone has had a good experience getting side gills installed on their E90 sedan.
