Roof spoiler effectiveness

[gonebuggy]

Driving a bug that regularly sees over 100mph, a rear spoiler is not what you need to worry about. The rear of my car stays nicely planted. but the front end starts to feel light. you can start to feel the steering loose it's responsiveness (very slightly, but still a loss) Not having run a front, or rear spoiler i cant say how effective they would be. I think a small "lip" over the rear window would help, but personally i'd concentrate on keeping the front planted.
