My 94 Accord is dropped 3", and I went to Sears Auto Center to get it aligned $54.99 for all 4 tires). There's a certain Auto Center that specializes in lowered cars. I went there, and they didn't have any problems. They even adjusted the camber kit I installed for free.
Also, when I was going to get my exhaust installed (it was supposed to be cat-back RS*R, but didn't fit right, needed custom welding). I went to one shop, and they said that I'd have to either raise the car up with the coilovers, or take the bumper off. Both are things I didn't want to have to do. I drove down the road, and asked Midas if they could do it. They said sure, and even had a rack for lowered cars. I watched the guy drive it up, and off, didn't scrape. But I also have stock lips and skirts.
