Rear Wheel Noise Reduction?

Need to reduce road noise? Install a bumpin' stereo system.

That definately works.

I had the car up on stands last weekend, doing the 7500 mi oil change and service check. I couldn't help but notice that the fiberglass (?) covers on the underside are like drumheads. What is their purpose? Airflow control? I am tempted to drive with them removed and see if the car is quieter.

Strap pillows to the bottom of the car.

Actually, compared to my other car this 370z is super quiet.

Just got my Z, and I notice that the road noise is rather high as well. But dynamat is heavy, I think we need to add at least 20 lbs of dynamat to the car to make a little difference. Is it worthy? I have done that to my GTR and didn't notice a big difference though. Any other lighter material available in the market?

I wonder if that might actually work?
What about a few "u-haul" type blankets cut to shape and placed under the foam in the cargo area? Kinda ghetto i know but it might be worth a shot...

So.. Anyone with a 2009 or 2010 have the spray?
