Sound proofing experiment on the 370Z

wow you went and did it to the plastic liners! i just plopped it onto the inside shell.

glad you got the change you were looking for without breaking bank!

Yea after doing the rears first I started to hear a lot more noise from the front. I figured since I was at it already might as well do the wheel liners.

Most OEMs use sound insulation on the wheel liners themselves.

Without going the extra mile and getting the car into a sound chamber, I figured I'd mimic what luxury oriented OEMs spent millions on in order to prevent road noise, the general principles are the same for all cars.

have you considered lining the door's aswell? i did my doors + hatch and rear wheel weels.

didn't bother with the floor under the seats or roof. i found i could hear the exhaust and engine hum a lot more clearly after i did those 2 sections.... but that's based on perception

I'm OK with the car now. I'd say 60% of the noise comes from the rear wheels and 30% from the fronts... 10% is other areas that are much harder to address
