I think your best bet is to locate a place that has all the BMW spec Hunter equipment. Not everyone has it and in my experience the places that do are generally pretty diligent about their work. A shop I used to go to out west was 40 miles out of my way and I told the owner that because he has the complete setup I only go to him. He was very pleased to hear it and informed me that it cost him a fortune, but all the stuff was absolutely top notch. Don't forget to get all your wheels properly balanced with the roadforce balancer prior to alignment.
