Base Boxster OEM non-drilled solid discs new:
front rear
24mm 20 mm

Brake discs Minimum thickness after machining*
front rear
22.6 mm 18.6 mm

* (from Porsche Workshop Manual) The brake disc may be reworked only symmetrically. ie. from both sides evenly - important point - don't just turn one side, take the material evenly from both sides!

Wear Limit
front rear
22.0 mm 18.0 mm

These are the specs for the Base solid discs. But, IMO, you should go by the 'S' specs as these are the ones the Zimmerman aftermarket discs are imitating.
