hi all,iv got a 57plate 1.6, i've got some 17"team dynamic mozas and lowered it 35mm on apex springs, I noticed a noise comming from the shocks when going over bumps, I only hear it when the windows are down it's like a swooshing noise like air being compressed if you get me? Only noticed it other week, couple of people said it's just the shocks taking the bumps, I'm just a worried theirs somthing wrong.
