Rear Wheel Noise Reduction?

didymus · 08-30-2011, 03:35 PM

I was washing my wells today and noticed what appears to be spray on noise reducer in the rear wheel wells. I also vaguely recall mention of the 2011 having some sort of noise reduction compared to the previous years. Do the earlier models have the same stuff? It is only in the rear wells, not the front.

I haven't heard of anything being changed for noise reduction. I sure as hell don't have any on my car. lol

hummm... i dont remember seeing that in my Z as well.

but my car does have dynamat all long the trunk floor and the cavity to the driver side quarter panel that i installed.

Here a pic of my rear wells and it's also a 2011. Not sure if that's noise reduction though. Maybe rust. Doesn't really look like much of anything. My G37 had wheels wells that looked to be some sort of velvet material.

I was under the impression that the spary-on material in the fender wells and under the body was only for rock/weather/elements protection only.

I don't think it is intended for sound..

If you really want to reduce your noise, switch to a lower tread wear rated tire.

Ken - did you find the dynamat made a noticeable difference?

Just put a couple bankets on the floor of the cargo area if it bugs you so much.

I'm not bothered at all; I was just curious if dynamat worked. One would think the Z would be a pretty good test for it.

I always wondered what that thumping was.

Doesn't bother me at all, just curious about the spray

This is correct, if you want sound dampening you need it on the Inside of the frame. Any 'spray-on' coating is not going to be enough to counteract road noise to the level you're thinking...

somebody should try spraying Plasti Dip. I think it would help cuz that stuff is rubbery

LoL It won't do anything for sound waves, all it will do is bounce the debris back into your wheel well.
