hmm looks like fiberglass not the greatest material for a front or rear bumper.
Email the pic to
precisionporsche.com they make knock off fiberglass parts for the Boxster. They have a ton of pics on their website.
But for the price I suggest going with a factory 911 GT3 MK1 (1999-2001) bumper which will fit your Boxster. DPS has them for under $1000. Mine has been sitting in the closet for over a year
