Agree with SLED, drive normal and don't be stupid should be alright. In saying that got pulled over by two cop cars (not just one) for a 'spot' check. Did a random breatho, looked through inside the car etc then disappeared. Been pulled over a few times and car is stock height with minimal mods.
As per above, don't act like a dick to cops and don't be stupid in traffic (or elsewhere in public).
