went and had them checked at another shop today, both fronts were off. the right front needed .50 and the left front needed .75. went and tested it out at the speeds I was getting the shimmy, only had a mild shimmy around 60-65 mph. went home and parked the car, then drove it later and the shimmy had returned at 50 mph. next step is to try breaking them down, rotating the tires 180 degrees on the tires, then remount and balance them per Tire Rack's customer service line's suggestion. if this doesn't help, I'm sending them back for another set under warranty.
