As far as I know, there are no spacers that will allow 996 wheels to fit the Boxster - they are just too wide. I suppose that you can change the wheel offset by machining the wheel, but I would not recommend that, as it would probably compromise the safety of the wheel. There are plenty of properly-sized Boxster wheels out there - I would look for the ones manufactured specifically for the Boxster.
