Right. Mine has scraped on some speed bumps and almost always on my own driveway--for years now. The lawn edging bends and snaps back. It is very durable. But over time, it has worn one or two mounting points, and I have had to repair. Extremely minor. Done in a couple minutes.

It's only scraped a couple of times since I installed it. At the bottom of my driveway, twice, when I was going down it fast, and when I pulled out of a parking lot fast across a gutter. I thought it would scrape on everything, but it hasn't. Mostly I'm wondering if too low will hurt aero, but I haven't been able to get a good run down the roads I frequent to be able to judge it's effect. It was super windy yesterday and rainy today, both would skew a informal test. It does seem to have better front down force and less body lift at speed, though.

I'm all in favor of scientific procedure, but not to the extent of undoing something as universally proven as an airdam. Too much work for no tangible reward. Then you have to reinstall it, even more work you could have just left alone. Plus the waste of time you could have spent on the undertray, enjoying even more MPG, so your removing it actually cost you even more $ than you thought.
You do want the tray sloping up from the rear axle up to the rear bumper.

FYI:
I've uploaded pics of the dam in question from the photobucket stream to post 1. |

what is the current ground clearance of your airdam? also how far does it extend from the bottom of the bumper? out of all these air dams your one looks like it would suit my car best!

I am sure he'll add his info when he returns next to this site, but my car and airdam are quite similar in materials and dimensions. I went out and measured: I have 13" wheels with 165/70 tires (slightly shorter than stock wheel/tire diameter) and my airdam's clearance from ground is 10.5cm and its face is 9.5cm tall.

what was your results with the airdam? my cars front bumper sits a bit higher but I think im going to keep the face same as yours but bring it lower towards the edges to deflect more around the wheels

I don't recall ever testing, because it had been tested many times by others. I just selected one of the best designs, modded the thing to my needs, and went with it. The butt-dyno suggests it makes a big difference. I consider it one of the most effective mods possible. And it is so cheap and easy!
