Hey guys I am lowered on the h&r race springs and stock sport shocks on my 335 coupe. I have this really annoying noise that sounds like a old squeeking mattress is the only way I have heard it described that makes sense. It seems like it is coming from the front right side. Any ideas it does it when I go over any kind of bumps small of large. Thanks

I have eibach springs on my E92 and I get a similar sound coming from the front but it doesnt happen over all bumps and holes.
Anyone have any ideas? Eventually, I may want to drive with my window down...LOL

When was the last time you greased your bushings?

Are the H&R race spring a progressive type of a spring? If so, look at the coils that are closer to each other, are they binding(hitting each other) or close to bind with the car on a level ground?

Did your tech install both the upper and lower spring pads? If not, those springs are driving to drive itself into both the upper and lower perches, which are metal and can cause the noise you are describing as well.
