i slammed my car and i love it.but now my problem is that it makes more noise on the inside. is there a product that can reduce the noise down. i know its a spray where u spray on the wheels but does anybody know whats it called and does it work?

 

theres a undercoat spary that they sell at advance auto parts that ive heard that works pretty good

 

Get an alignment, or it might just be the type of tire you have. Some tires make a lot more noise than others.

 

hows ur build doing bro?

 

You could try a sound deadener such as Dynamat underneath the carpet, and behind the door panels.

It's probably going to be near impossible to get rid of all the road noise though, especially since the car is slammed.

 

Elemental Designs eDead products are pretty sweet. They have a foil-faced butyl rubber self-adhesive product in various thicknesses for damping lower frequency noises. It's similar to Dynamat products, but MUCH cheaper. I lined my entire car with the 45-mil stuff, applying 2 layers in some places. The 45-mil product goes for $1 per square foot.

They also have another product that is like a dense foam, self-adhesive, about 1/4" thick. This will damper higher frequency noises like tire noise and road noise. I think it runs about $2-$3 a foot.

By comparison, Dynamat usually runs about $8-$10 a foot.

 

Good info, I've been planning on lining my car with something, but dynamat is wayyy expensive. I'll for sure check into eDead products from what you've described it looks like it'll fit what I want do perfectly.

How is the quality (how much quieter is the ride), was it worth the costs?

 

Well I actually didn't do enough research, and I didn't know about the low frequency vs. high frequency deadening when I bought the butyl mat, so my car is still fairly loud inside because the butyl mat is mainly for lower frequency, and road and tire noise has a higher frequency.

However I have heard of people putting the foam on top of the butyl mat, and also sealing up the doors pretty well (which I didn't do much of) and it made a much bigger difference.

 

Would the foam be too thick to put underneath carpeting? Is that something you'd put in hidden areas? Which would be the best area of the chassis to use the foam (besides the doors?)

I'm assuming the butyl mat would be good for an audio setup as well?

 

Not sure, you might want to check the eD forums to see what people are doing with the foam stuff.

 

Will do.. Thanks for your help man!

 

This may be what your talking about.. If not it's probably very similar.
