Ok, just an update. My experience was excellent; the parts were installed, perfectly customized (they even re-directed my rear wire harness for easier access when towing), and the paint work was great.

If there is anyone on here with a towing package unsure about getting the aero kit, or anyone local in the MD/DC/VA area...or even someone who just needs their aero kit painted for a low price, let me know and I'll hook up up with these guys. BTW, the price for me to get done all I had done was $550...for everyone else, it's $650. I don't get any kick-backs or anything like that; it's just that he realized he charged me too little for all the work and told me everyone else would be more.
