Hi all, I have a Wilwood bike rack
Willwood System - Porsche Hitches and Bike Racks the used to live on my Boxster. The Boxster is gone, but the rack remains. The system is designed to mount to two female brackets you mount on the boxster bumper, I do not have the mounting brackets, but you should be able to get them from Wilwood. It has worked like a charm and it was always a treat drive to a bike ride with the top down on the boxster. Asking 150.00 plus shipping. I have more pics if interested edevlin@hsc.edu
