Looks great man! I did this last week and from what I've seen of mine, I like it too. I just need to see it on the car to get a better feel.
I did the mod with my bumper off too. Although, I don't know from experience, I feel this is the easiest way.

I ended up measuring out the entire area with a tape measure to ensure that it was well balanced all the way around. The only thing I don't recommend is the Loctite double sided tape. It wouldn't stick to the garage lip for anything
Anyhow, here are my pics of it installed. I'll post some more when I get the bumper on the car.
Here is what I used for the lip.
