Gran Turismo East in Chamblee. They have worked on 2 of my NSXs and several more of my cars. Their alignment tech has been doing alignments for the Road Atlanta crowd for 30-40 years. My current NSX is about 3.5in off the ground at each jack point and they were able to get it on the rack. I'm not sure about lower but I think your setup is probably not as low or at least not any lower.
I'm not an expert, but I don't think you are going to get your alignment back to factory camber specs without camber kits. I wouldn't even worry about it though. Just as long as toe is OK. I'm at -2 front and -3.3 rear for camber at my ride height.
