I'd take Race Related off that list and put fordspeed.com in place of it. Joe at fordspeed is a cool guy who knows his shit.

I had my gear install done at race related and wasn't at all impressed with customer service (waited over an hour there to pay and get my receipt while my car was sitting there done) and the fact that he said he'd put it on the dyno for me and never came through. They may not be too bad, but that was my expierience with them
