LOL, me to.
Most times I get pulled over the cops look in the window and go "um err, we are pulling you up for a random breath test" they then walk back to their car and get the thingie.
Some times they ask about the mods and I give them my folder with the rego, insurance, cams licence, engineers report, they then have a chat about the car, ask me how fast it is, I usually say "its pretty quick but it would be even quicker with a better nut behind the wheel, I laugh, they laugh, and then Im on my way.
Works the same when Ive been pulled in and the RTA are there doing vehicle checks.
Never a problem.
