I'm new to the forum and have had my '01 Boxster for 5 years. The wheels I have I believe are Porsche factory, but I haven't seen them on any other Boxsters or other models for that matter.
Def not factory - sport classic II I think are 3pc look/design from era. Appear to be HRE or HRE knockoffs from same era though. Hard to find silver P-crest center caps so nice score there along w chrome wheel bolts to complete. Guessing base as well but a PO at some point painted calipers red.
