Let me preface this by saying I'm not an alignment expert and I didn't stay at a Holiday Inn, but the explanation I was given as to why to have a touch of toe out on the rear:

When the rear unloads under heavy braking, a touch of toe out becomes neutral as weight is lifted off the rear. This is desirable when entering corners vs toe in.

It was Porsche of Omaha's service mgr who told me that, they've done many 'racing' alignments, and seem to know what they're doing with the proper alignment figures. I have no reason to doubt them, but once again, I'm not an expert. At the time I had my alignment, I had my CSS in to add GT3 LCAs on the front, Tarett monoballs on all 4 corners, and Tarett thrust arm bushings in the LCAs. I also have Tarett toe arms on the rear. When the tech got done with all the changes and the race alignment, he told the serv mgr that all Caymans should be set up this way, as he thought it handled on rails when he took it out for a test drive.
