Now that I have had enough chances to open up the car on a consistent basis I just keep noticing that the wind really can toss the car around at higher speeds. In my head in just saying slap on a wing and diffuser and presto... problem solved. Is that realistic? How much of an impact would they have. Unfortunately I am factoring in how well the wing looks so the more functional ugly ones are out of the question. I was looking at the GUT combo. Any other suggestions?
