As MZ-N10 points out, our spoiler serves a purpose and even though the Stealth looks similar it can't replace the VX's feature. Take a good look at the underside of our spoiler and you'll see what I mean. It really isn't a spoiler at all but serves two important functions. It directs air over the rear glass to keep it relatively clear in the absence of a rear wiper, but more importantly it smoothes the airflow at the most turbulent portion of the body which reduces drag. Lose that spoiler and lose a few miles per gallon.
