I read all the way through and would also share my experiences regarding tyre noise and wheel wells issue.

I have driven the 370Z with Stillen Exhaust and air intakes with the same 20" alloys with 3 different set of tyres:
Falken FK452...oh my god, that is not only a cheap tyre but also so noisy that the sound level at 65mph on a highway is more than annoying even with an Stillen exhaust (on demonstrator car only)
Bridgestone Potenza RE050A...I think that's the same like on the stock alloys. Well, still little bit too noisy to be considered as good (5 days on my car. because I want a wider back tyre I let my Nissan dealer change the tyre brand)
Last but not least: Pirelli P Zero...this tyre is not only more expensive than the Bridgestone and much more expensive than the Falken, it is also much more comfortable to drive and the street noise is now at an very acceptable level for me. Sure I don't like a quiet 370Zzzzzzzzz car therefore we have added Stillen exhaust and intake and even the engine makes a nice deep sound, but the uncomfortable roaring of just some dam cheap tyres is just gone. Sure it will never be sooooo quiet but sorry, that is a sports car and not a limousine.

But in my opinion that is already a big improvement compared to the noisy stock or even Falken tyres....so change your tyres and ask your tyre dealer for a comfortable and quiet one....if not, just bring back the noisy ones.

Second and still annoying noise from the outside of our car is indeed the pebble noise when just picking up each stone one by one or even as machine-gun fire passing some new tared roads...

Nissan's 370Z GT has some suspension modification but they also have done some "extra underbody sound insulation"
Someone has some information about this? Because if they add some extra sound insulation stuff each Nissan dealer should be aware of and could give us some extra parts/info????

I like this topic even sound is like colours a matter of taste so everybody has different feeling and intention with that! But I drive a 99 Yamaha R1 as well so I never ever hear anything else than exhaust, airbox or the engine...and that's good
