Is this new? Or have you experienced this since the frame was straightened???

I had the same problem but at about 75mph. I had 4-wheel alignment, didn't help. Although my rear struts need to be changed I put on some new rear tires and it solved the problem. Hope that helps.

are you sure it's a sway as a result of the car itself and not just following the "ruts" that are dug into the roads by most other traffic that is slightly wider than the boxster?

i notice on some older roads that have not been repaved in quite some time i can ride in one "rut" or the other, but not both and this causes the car to feel like it's kind of going from side to side in the lane...

what kind of tires do you have? same tires front & rear?
