Not complaining, and I know the Z is a sports car and LOUD inside, but, I seem to be hearing a lot of rear tire noise from the interior. Right under the plastic coverings under the small windows.. It seems like the wheel well is not insulated. This happens especially during rain or driving through gravel, when small rocks hit the top of the well.

Is this common or am I missing some foam insulation?

 

i hear these random buzzing noises from my dash, they sound almost like a bumble bee. they appear randomly and are not from the stereo, if i push down on the area of the dash that is buzzing i can make the roises subside for a while.
