Spent about an hour last night playing with the air dam. I had to do some trimming to get it to fit on my bumper. Luckily the material is fairly easy to work with, and a razor blade worked pretty well.

Notes:
- I should not be trying to do this stuff, I am not very good at this. I can't cut straight.
- Clecos, I don't need no stinking clecos, I've got wood screws!
- I'll have to take the bumper cover off to go rivet the dzus springs in place
- I have only drilled one dzus hole for the front attachment point. I still need to drill the other 4, and go and rivet the springs in place on the bumper cover. Hopefully tonight.

what material are you using?
Is that white honda badge IT legal?

 

The dam is from SBMS, you'd have to ask Tom Blaney exactly what kind of material that is - it is some kind of soft plastic.

As far as the badge, LOL.
