You can also verify this with Bilstein, who manufactures the stock struts for the Boxster. Their "HD" series have increased damping over stock Boxster S dampers, and are equivalent to the USA M030 dampers. The "Sport" series has a shorter length for lower ride heights but the same damping as the HD series.

after a bit of research, the damping WAS different between the base, S and Sport. For the front dampers, this is still the case. For the rear however, the part numbers have all been superceded by the 'S' versions; no matter whether your car is a base or an S you get the same part. Strange.
The M030's are indeed valved differently than the stock dampers. The ROW and USA versions have the same compression and rebound rates, but the damper rods are shorter on the ROW version so that the coil springs don't unseat on full rebound. Thanks for catching the mistake.
