Its pre cut & it just drops in. Place it right over your carpet in your cargo area (there is not no adhesive).

We want to know if C4 owners experience the same tire/road noise in their interior.
This appeals more to certain states like Texas, Cali, Florida....etc where the roads are either concrete or have a top layer that make the tires roar! .




Real quick and real effective against road & tire noise and takes the edge off exhaust. We have sold thousands since 2008 for the C7, C6 & C5.
You can read more about it here.. http://store.tkoperformance.com/20c7blsodesy.html

I wanted to know if C4 owners have similar noise issues & could benefit from our mats. Certain states (like Texas, Cal, FLorida...etc) the roads are either concrete or have a certain top surface and it makes the tires roar!


(Installed in a C7)




1 You get a lot of tire & road noise?
(What state This applies especially to people in certain states like TX, FL, CA, where some roads make the tires roar.

2 Stock or after market exhaust to loud for long trips?

3 What year do you drive?.

4 Coupe or vert?


I appreciate any help. Thank you for reading this!

This is strange to me since the driving experience is not particularly noisy. Maybe it's the tone of the noise which is a low rumble almost all the time.

Not particularly, the level of road noise really does depend on the pavement type and condition. Concrete generally tends to be more noisy than asphalt. But grinded/smoothed concrete can sometimes be quieter than asphalt. But there is no question that broken pavement is the worst in these cars, and I have the base FE1 suspension that is pretty soft. I'm running older Goodyear Eagle HP tires that need to be replaced - the rubber is hard, which may be part of the noise problem.

2 Stock or after market exhaust to loud for long trips?

Stock exhaust, low to moderate noise levels, not too loud at all. Long trips are a breeze.

3 What year do you drive? 4 Coupe or vert?

1995 coupe LT1 6-speed

Since it is visible, I expect it to be rather inexpensive.
Its pretty easy to remove the carpet and add dynomat.

So in your case it sounds like you have a bit of road noise but your not falling into a real "annoying zone".
Thanks




The whole idea for this thread is to see if any C4 owners are experiencing interior noise issues. Certain years within the C4 gen could be worse then others.
Over the years we received a few emails asking for our product for the C4. I wanted to look into it and see if it was a bigger problem first.

However, when the Blockit was originally tested back in 2009 (for the C6) , a Bruel & Kjaer ( #1 in sound and vibration equipment) Model 2250 Type 1 Sound Level Meter was used and it was ran by a trained sound engineer.
It knocked down 8dbs. Even though that's an incredible number, since then we have even improved on the product.

Thanks

Well I'd be willing to test your product and report back. C4s are a noisy generation normally its tire noise due to road surfaces and exhaust. C5-C7s are Cadillac quiet by companion lol. If you need a tester I would be interested and I have a dosimeter to do a before and after test

Actually if its visible and not hidden, aesthetics come into play which should make any product more expensive. However the system is not expensive.
You might find removing the carpet to be easy, but it still equates to a few hours. Id take a 60 second solution over that any day.
However if you were going to remove parts of the car & the carpet, I would use DeadMat over Dynomat anyway.

Thanks


Thanks for the feedback. Keep it coming.

3. 93 Z07, automatic

4. Coupe

I can do a data run of before and after freeway runs if you would like. I like the idea of a mat to protect the carpet as well. I run a Corsa exhaust system which is pretty quiet so. It would be a decent test platform. 8dbs is significant if it is even better now I would love to test it. Have you a test mat to experiment with that fits the C4 yet? C5s and C6s are Cadillac quite compared to C4s. GC

2 Stock or after market exhaust to loud for long trips? The Magnaflow I had wasn't too bad but did drone after a while. The Corsa I have now does not drone at cruising speed but is very loud around town when going through the gears. I already have Frost King foil adhesive under the carpet but not much effect on interior volume.

3 What year do you drive? 1994 LT1 6-speed with the base FE1 suspension.

4 Coupe or vert? Coupe

Sorry buddy, I accidently skipped over your reply.

OK so 94 and your in the warm stage..
You had some drone with the magnaflows which I find to be common. But you changed to Corsa which is quieter which is also common.
But you have some tire noise. FL is another state where we sell big to. So I understand the road/tire noise being an issue.
Sounds like you have issues BUT is it to a point where you would want to do something about it?

That's what I'm looking to zero in on. The other gens was a no brainer.
I'm not sure about the C4 gen

With regards to the, "Blockit Sound Deadener," it looks like a solid product and searching around on the forum also shows positive reviews. My interior noise isn't objectionable by any means especially for a 22 year old sports car. However, if you offered this product at an appropriate price level I would be a customer. My rear cargo carpet could use replacing and I could also benefit from some more sound deadening-essentially killing two birds with one stone. If you price it at $215 like you have for the C7 I don't think you will attract a profitable amount of customers in the C4 Market. Most of the cars in the C4 gen are $4,000-$8,000 cars, so the market domestics would be working against you as most of the owners would rather spend the $200+ on other performance upgrades or repairs. C6+ Owners are generally older and have more disposable income for little add-ons like floor mats and sound suppression. I believe our cargo floor space is a little smaller than C5+ generations, so if you could place this product in the $125-$150 range while still maintaining a decent profit margin I think you would have a hit. There are still quite a few members that are die hard C4, and even though they have other gens they will always keep their C4, this is the niche you would have to go after.

What better way then to reach out and speak directly with C4 enthusiasts.

As far as cost,...
I have not measured the cargo areas yet nor have I looked to see if the car would need 3 pieces or just the one cargo mat. I need to add "If you do experience unwanted road noise is it coming from the rear?"
Again this was the first step of many, to see if there was even a noise problem in the first place.
The size and the amount of pieces would impact the price.
But I can't base the cost of the product on how much a car is worth. Unfortunately the 3 piece Blockit system between the materials and the unique infusion process (so there is no glue), is not cheap. Its manufactured here in the USA and even the raw materials are also from here. Yes it cost a little more but I would not have it any other way.

I totally understand where you are coming from regarding putting $215 into something else rather then a sound deadening mat. But what good is a new or better upgrade when you can't enjoy the ride. nothing ruins and creates fatigue faster then unwanted noise in the cockpit.
If your not considering it then its very possible its not that bad for you which is a good thing.

The people that choose to own a C4 regardless of what it costs would be your true target market, and ideally, price wouldn't be an issue. Just trying to paint a picture of what the C4 market is actually like. Whether that is interpreted as good or bad is up to the reader. If this product does what it says it can do in the description, than I think it has a place in the C4 Market. Yes these cars are noisy (the rear hatch area especially), they are less refined than later generations. If you could offer a 3 piece kit that is as simple as laying it down in place what is not to love? Dynomat or Dynomat equivalents are great but it does require a lot of work. This is just my $.02 and trying to give honest market research to you. I think we all appreciate anyone who still supports or is considering to support the C4.
