Excessive road noise, help!

[LRG SOUP]

Hey everyone I have getting a lot of excessive road noise when traveling 40mph+ and its coming from the rear of my e30. I do have the spring pads on my rear coilovers as well. Could it be the top hats for the shocks that are worn out? or suspension bushings? I have to turn up the radio to drown out the road noise. I am also on new falken 912s so I don't think its the tires. thanks if you can help!

If anyone has any ideas that would be super helpful. I feel like I have off road mud tires on my e30.

1+ on OPs question... I too am amazing shocked at the AMAZING difference between driving my e30 m3 and my e46 wagon.... I was thinking weather stripping on my car might need to be replaced. I can sometimes hear wind almost as if my window were open JUST A HAIR...

No one? Would dynamat make much of a difference?

are your windows down?

Are you sure none of the noise is coming from the differential?

I just swapped in a 3.23 lsd from a 99 m coupe, so not the diff for me. I feel like I get a good amount of noise from the engine bay and transmission tunnel. Would a worn out guibo add some noise?

Oh what the heck, no wonder I couldn't look at specific messages through my phone. I mistakenly made two accounts. Thanks for the headsup!

I was thinking the same as well. I was gonna place it behind the rear seats and around the rear shock towers in the trunk but i'd rather pin point the issue at hand rather than put a band-aid over an issue.

are your windows down?

up or down. either way the road noise is very annoying

Are you sure none of the noise is coming from the differential?

I have no clue, all I know is that its coming from the rear of my car at 40+ mph or when getting off a highway exit slowing down to a stop.



If anyone has any more suggestions please don't hesitate to comment. thanks!

The 40mph+ bit still points to diff noise for me, unless a CV joint on a rear half shaft has gone bad.
