No spacers on the factory wheels. I prefer not to have any spacers at all to avoid beating up the wheel bearings. And for autox/de I really don't want them on because of the stress.
But for the short winter months where temps go below freezing I can deal with it.

I'm not sure who makes my spacers but the guy at Wheel Dynamics has a kit for these particular 10" wheels. He was well versed in the issue with fitting narrow body Carrera wheels to the rear of a Boxster when I called.
