Gentlemen Need your help please. I’m having trouble trying to diagnose a noise coming from the rear passenger area of my 2007 GT500 with only 5k miles. The noise that I am hearing is a constant hissing/white noise. It only does it when the car is in motion. It does not go away when applying the brakes or pressing in the clutch. I checked to see if the Ebrake lines were rubbing and that’s a negative. It doesn’t get louder with speed just a consistent noise. I thought it was the caliper rubbing on the brakes/rotors but seems not to be the case? All I had installed were some racecraft lower control arms, Eibach sportline lowering springs, and a racecraft adjustable pan hard bar. All mentioned parts have been on the car less than 100 miles. Is this normal to hear that? I know when messing with the suspension you are going to get a lot of road noise but wasn’t expecting this. If this is normal then I will be fine with it, if it’s not ill be taking It into the dealership to get it looked at since I have warranty on it. I had my son record the noise but having trouble trying to load the video on youtube to post on here. Thanks for your time.
