A service guy at Town North Mazda (Central Expressway just south of Belt Line) told me they will do custom alignments to your specifications. Cost is under $100. I'm not sure if they'll let you sit in the car, but you could call them. Ask for Victor in Service. He's the one I talked to about it a couple of weeks ago.
I won't be in a position to recommend them or not until I've had them do an alignment for me. I'm planning on that within the next few weeks, early January. Then I'll be able to give you some personal insight.
