I've been riding on KYB AGX's with Intrax springs for a good 8 months now. It seems like after the springs settled, the back of my car is making some annoying noises. Im not exactly sure what is causing it, but I can only assume from the sound that it is the tire making contant with the wheel well, sort of a low pitched humm that only occurs when turning and going over a dip in the road. I have almost a 2 finger gap in the rear FWIW. My question basically is, are there any other possible problems that could be causing this noise besides the tire hitting the inside of my wheel well. I ask mostly because I seem to be the only person who is experiencing this, even those on Sprints with a coil cut in the rear.
