No I don't think so.... however, as I understand it, the speed rating isn't just for maximum speed. It also has a lot to do with the handling of the car due to the flex of the sidewall of the tire. This can have a bearing on the overall handling of the car, and potentially loss of control under severe driving conditions. But, I don't think of the Forester as being a high performance car. Higher speed rated tires are normally associated with the performance cars.
