I think the chin spoiler and the rear deck spoiler are there for going at very high speed? I like the rear one. It looks too much like a plain, ordinary car without it. But I definitely don't like the front spoiler. I can imagine bumping into stuff all the time with that. Plus it doesn't look mopar. Whenever I pull into a driveway I have to hit the brakes just before I enter it and go slowly, otherwise my front end hits the pavement. And I think I probably have a little more ground clearance than the Challenger.
