rear spoiler noisy

i had facing so many years.my cars rear spoiler is making noisy sound when im driving through out unstable road.i'm worried if its been removed,the cars aerodynamic would be unsufficient.any advises?

as in it vibrates? you could pull it off and put a layer of rubber or foam in between it and the car, or even just make sure all of the bolts are tight on it.

Also, you civic will rarely go fast enough that the areodynamics of the wing will actually matter.

on top of the fact that the spoiler wont do anything for you at the slow speed of your civic, should you get to high enough speeds you may find that staying on the road becomes harder, not easier, since you drive a front wheel drive car

lmao..........only ricers believe it will make it go faster and it looks sick....my opinion is it looks gay...less weight...one thing less to worry about from somebody breaking with a bat...and less birds on your car...lol

iono ive seen some of the smaller, tasteful ones that look pretty clean, but thats just it, its jsut for looks
