Jeff,
My advise (for the little it's worth
)
1. Make you it's nice & clean. And that includes making sure there's no leaks visable etc.... IMHO if it looks like a un unclean POS they'll be less keen to be lenient....Not calling it that but ya knows what I mean....
2. I WOULD look at fitting the front stock bumper ends - under the ADR's there isn't supposed to be a gap between bumper & guard (as I recall) and the bumper should be full width - so although ugly as sin, I think it's just one more thing they might ping you for otheriwse. Oh yeah I still have my old ones too.
3. Is your speedo set right? If not get it adjusted. Also make sure your steering stops are set right, and put some balck paint on ANYTHING that looks like it's been rubbed. Inc lower control arms, spring perches, inner guards, chassis...anything....
4. Smile, be nice and offer sexual favours
