Downforce? The only street cars with any kind of downforce are very expensive exotic cars. I'm talking stock vehicles, not the cars that have giant wings tacked on. For most street cars you are talking about lift, or the lack of it.
It's probably a worn out suspension that is your problem. If your shocks are worn out, it could certainly give you a floaty feeling at higher speeds. How many miles are on your Boxster?
The fastest I've driven my '02 is 130 mph, and it felt fine, but I have refreshed my suspension completely.
