Soooo, as part of my Boxster project, I ordered a set of "Speedster Humps" from Extreme Dimensions. The first time I had them on my car, a factory installed bracket failed and the right one flew off my car at 40mph (thank God it did not hit anyone) I am in the process of attempting to get a replacement from the manufacturer. If I do, these things obviously need to be beefed up or more brackets/fasteners added. Does anyone have a set of these? Did you add any other support?
