um no they cant cause cops are stupid, unless a cop is into cars he has to prove in court that the mod was illegal, but if you have engineers certificate just wait till he writes up the ticket and say to him/her 'didn't you want to see this?' GOLD

if they say 'why didn't you tell us?' you say 'you didn't ask so i thought i'd waste your time because your wasting mine' GOLD again

obviously you don't know your rights so i'd get some information about what you can and can't do to a car (and every car is different) and get educated

im not trying to be a smart arse, but you seem the type that will ask a silly question and say but why can't i do it?

I'm 33 and have owned cars from rotary's to v8's and i have had my share of cops being dickheads, but i knew how to put them in their place as i knew that my mods were legal and they didn't know their own job.

just for laughs i'll tell you a little story...

I got pulled over by a toyota camry wagon (yes wagon, undercover) and they said to me we were following you back there through the shopping centre streets and clocked you doing 70+k's in a 60k zone. so i said where's the radar? they didnt have one. me 1 them 0.

then one of them proceeded to look over my cordia turbo and i went to look at their car, the other cop was stuck in the middle and didnt know what to say. if they want to look at mine i'll look at theirs

they could not do sh!t cause there was nothing illegal done to my car that they could pick. but it helps when you got an uncle thats senior SGT and lives close by

they can't even look in your car, under your bonnet or in the boot UNLESS they suspect you are carrying drugs or something illegal or you get arrested. other than that you can tell them to jump of a cliff. its like them coming into your PRIVATE property and if you dont want them there you can ask them to step onto the foot path. they cant say no or you can have them up for trespassing. you as a citizen have more rights IF YOUR IN THE RIGHT than any cop on this planet, just depends what country you live it

anyway my fingers are getting tired, but i can tell people more wonderful stories
