I live in SD. Sorry but I don't know this shop.
You may want to call Dan at Dan's Precision Alignment. He does all my Porsches and is very knowledable and a straight shooter.
If this is straight up, Dan would know. If it is BS, he would be willing to tell you that too.
His number is 760-753-0481. Tell him Rich Belloff referred you.
Let us know what you find out!
Thanks for the post. Interesting!
