To prevent road noise? Seems like that would do an appreciable amount of insulation if done right. Just a thought...seems like this car always suffered from road noise and as it gets older, the worse it gets

 

Tires are the #1 source of road noise.

You can insulate the car a bit, take the front wheel liners out and spray some rubberized undercoating onto the inner fender area. Re-undercoat the rear fender wells and undercarraige.

Again, a nice quiet touring or all season tire is your best bet in making your Max a quiet car again.

 

i was considering this, just so happens alot of the tires i like alot make a considerable amount of road noise. Im curious to see how much of a difference this could possibly make.

Doesnt Dynomat make something specifically for this? Not just regular dynomat, but stuff ment for the wheel wells and engine bay?

 

good idea....

 

i'm pretty sure i've seen threads about this exact idea in the audio/electronics forum

 

I did my entire underneath of my I30 when I took off the oem exhaust to put on my Greddy with rubberized spray on coating. I didn't do the wheel part because it is plactic. I coated it after grinding any rust and spraying a layer of rust preventer first and let dry. Now the entire unddercarriage is black, crossmember, rear beam, trailing arms, etc. looks 10X better than before. I really didn't notice any sound reduction really, just looks alot better. But the
I30 has more sound deadening than the maxima to begin with. If I was doing this for sound reduction I would get the spray on type from a car stereo shop, specifically for noise reduction. Might be a little more than the rubber coating but will work better in terms of sound reduction.
