After more researching, I think I see what Berg is getting at. Depends on the desighn if its a spoiler it disturbs air flow to eliminate the air currents causing lift, and does not generate downforce. Where as an air foil generates down force. Looking at a physics page on spoilers and air foils, the boxster appears to have an air foil. The owners manual says its a spoiler, but the appearance is more airfoilish. Lol

Found another discussion on Pedros board, which did not help seems there is no agreement if it creats down force or not.

So I revert back to the buttometer ansew does it feel more planted or not?
