This is a Skoda Superb TDI. I checked with the workshop and they said they dont have it in stock and not available anywhere in India in stock as of now. If required an order will have to be placed and it is very expensive. He said it could cost upwards of 30K

Check with Pai Auto at Santacruz (Tel: 022 2661 4798) if they can arrange for an OEM unit. Either way, their workmanship is good and they would do a good job even with an aftermarket liner if you / they can arrange for one.

2 issues:
1. Could be too thick when applied over bends and discontinuities - will not hug the profile
2. If density is too less, damping will not be efficient

I eventually bought 44 sq ft of Dampmat Exceed. Installation will be done soon.

I went for damping in my new MS Vitara Brezza. It was to tackle high NVH level inside the cabin. I went for all 5 doors damping in my car. Somehow, I m still not satisfied with the result. I m thinking to go for boot floor damping and cover other places which are not covered.

My question is, won't it increase the overall weight of the car? Is it advisable?

STP i SILVER ANTIRUST DAMPING sheets. Rs. 1200 per sheet. Used 5 sheets for 5 doors.

Did you notice any difference in the NVH levels after damping the doors? Perform a "rap test" on the outside of the doors and see if you hear any metal ringing.

Damping the boot floor etc. will not have as significant a change as damping the doors. Another source of road noise is from under the car and from the firewall but damping these areas requires you to remove the carpet and I find that in many cases they are not able to re-install the carpet as original.

That said even if you damp the boot floor and under the carpet the added weight will not make a significant change to your car's acceleration.

After all, all the damping you add will not total 20kgs (about the size of a big child). Even if you added a couple of amps and a subwoofer the effect on acceleration would be minimal.

Yes. NVH level was decreased after damping but not up to the marks. Noise is high on bad patches and at high-speed.

To tackle the road noise from under the car, I installed PVC carpet mat along with 3M Nomad floor mat. So, now I have two (in fact three, if we consider stock carpet) layers of mats on my car floor. However, these mats are not installed on boot floor, that's why I was thinking to go for damping of boot floor.

You can damp the boot floor but don't expect a huge difference from where you are now.

I think there is so much you can do to improve beyond a certain point. Alternate view point in my mind is that too much damping means lot more rubber which is fairly flammable in nature . May not be a genuine risk since most things are anyways easily flammable inside a car.

Another option could be the anti rust 3M rubber coating of the underbody. That also helps a bit.

3M anti-rust Underbody Rubber Coating is allready done. I think I have to learn to live with this NVH level.

What about tires? they also make a huge difference to NVH of a car. Are you running OEMs? they are typically not the best brands. Softer ones like Michelin XM2 would also help a fair bit.
