I'm considering lining the inside of the inner fender inserts with these 3M Sound Pads in hopes of cutting down the tire noise on less than smooth roads.
Do you think it will be effective or a waste of time?

If anyone has experience with this stuff or other suggestions I'd like to hear it.

Do not know that specific product, but know sounds deadeners can make a great of difference in our cars. Tire whine is the most irritating to me, and your proposed product, in the location you plan to put it in, will probably be worth four to four hundred times what you pay for it in terms of enjoying your car. Please report back when finished how,it worked, perhaps doing a simple DIY for us who follow you.

In the 2006, all Corvettes except the Z06 had a tube shaped sound deadened placed inside the inner wheel liner. While I was watching my car be assembled, I noticed that Z06's did not get it. When I asked why, I was told, "weight." Bought that GM parts, installed it and it made a nice difference, not perfect, but significantly better. Weight of the two tubes, total, was 1 pound.

The Stingray already has the 'felt' like sound absorbing liners in the wheel wells. I would have some concern about how well this would adhere and remain on the existing liners.

My exact concern, I removed several of the T15 fasteners and pulled part of the liner down, the upper side is much smoother than the down side you see (fuzzy looking)
3M products usually have very good adhesives so I think I'll give it a try and see how it goes.

Hope it goes well. Do you have any way to measure the sound decibels before and after?

There is an Iphone app I downloaded. It can give you an idea of before and after improvements.

Keep us posted on how this works out!

I did the rear yesterday, the fender liners are too light to put the 3M material on so I applied it to the outer body panel surfaces showing in rear wheel wells.
It isn't hard to do and the stuff sticks very well. I'll post photos and final opinion after I do the front.

Will this product hold up to wet weather conditions?

I don't think weather will hurt it, it won't absorb water and the adhesive is tough stuff so I doubt if it's going anywhere.

Good on you, not brave enough to do this and deal with issues if it doesn't work out.

There is another sound-reduction option. While not a supporting vendor, to my knowledge none of our vendors has this nor a competing product (and if I am wrong, would remove this post.)

Google: 2014 C7 Blockit "Drop In" Sound Deadening System

Install is a breeze (two minutes ,no tools) and am considering installing it in our Z06.

Note, update: No longer planning on putting BlockIt in my Z06; going with FatMax80 instead (see glen E's StingRay build site, for he taught me about this cheaper option.). If you have further questions as to why I changed my mind, not just cost, please PM me.

John, are you talking about the mat that lays down over the carpet in the rear cargo area for long trips?

That is what they (Blockit) describe their system as, though a bit more sophisticated than just a mat over the carpeting.

 

[regguy1]

Update, I've only done the rear so far I'd say it made a small difference in road noise.
The road noise is much less noticeable when top is off, I think the coupe design creates an 'echo chamber' that magnifies noise.
I will do the front when I get time and update.

Installed Blockit into our C7. Works great. I modified the installation and instead of laying the behind the seats pieces over the carpet, I slipped them under the carpet so that they are against the wheel well. Makes a big difference with road noise. Stereo sounds great but can still hear that awesome exhaust.

Elegant I and others are using a $60 product to deaden the bulkhead behind the seat, takes an hour and just sissors...peel and stick....A HUGE DIFFERENCE.....off amazon 80 ml material

More info set by step in my build thread

Please share the starting post number for this in the build thread. I see more than 500 posts!

The sound improvement is a little better in the C7 vs. C6, however, I've noticed that on a concrete highway, noisy as hell, but once I hit the macadam/asphalt road (usually highway), it gets very quiet. Still debating if I want to add the sound deadening material.

I think it really depends on the roads and road conditions that you find yourself driving. When I am not on throttle (that actually happens a couple of times when I take her out ) RedHot is just about as quite as my XTS most of the time. I haven't found the need for sound deadening material, though as Glen and John have demonstrated, it seems to be a pretty easy and inexpensive fix it you need it.
