tire noise after some suspension mods
Hey guys need some help, just installed eibach pro-kit, dspecs and spohn ajdustable panhard rod. The car drives fine no wheel shimy but there is a tire whine or hum. Anyone have any idea what it could be?

Here is a link to an article that talks about checking the pinion angle

Angles outside of spec result in more noise.
Your Panhard bar was installed with the rod end on the axle and the poly end on the frame - correct?
As the poly/rod panhard rod now transmits more noise than the rubber bushings in the stock one then what you are hearing is probably more gear/tire noise from the rear axle.

I doubt very much if it's an incorrect pinion angle causing your hum and whine. My experience is that this was more of a shake or vibration. Sounds like it's NVH through your new adjustable panhard bar because of those wheel alignment areas that Sam previously mentioned. Hold on now, because Noises (NVH) get even worse with an Adjustable upper control arm.. etc..
