Glad that you're happy with the work Tag did for you. I have my appointment with them for next friday to get the ACS springs installed on my 550i. I was a little worried because apart from the yelp reviews and the Morr wheels vendor, I had not heard anyone really vouch for their work on this forum. So I'm glad your experience with them was positive. Alex at Tag has been great so far over the phone. He tells me that they do work for several dealerships in the SD area, so that's encouraging.
