Got 9sheet of dynomat for 100$.. not to bad a deal..So im going to try it myself..

Earlier in the month had a shop look at it and was thinking about having them deaden my car for me.. He started tapping away for the biggest rattle points.. said the Roof was the worst.. I am just thinking of doing the doors and the trunk/hatch... Will this be good enough?

Also I didnt get the roller.. As far as I am concerned I dont think it will be that hard to fnd a replacement roller*doh* but all is there anything else i should know before applying dynamat other than cleaning it with rubbing alcohol first?

Any other tips on little places where to place the mat? ; Also Should you place the dynmat behind the window track*right on the backside of the door* or the metal infront of the tracks.. or both? *Im thinking both...derr

Be gentle :}

Look in there.

 

i just got done looking at that thread before i made mine.. Lol just wanted to get an opinion just to make sure before i go all out ;p

 

I didnt do the roof. Both sides of the doors were done and the trunk. The car does not rattle. Im not sure if 9 sheets will do all that though.

 

Both doors.
Entire trunk area including the hatch.
Entire center piece.

 

entire center piece.... = ??

 

I would appreciate it if I can find out how much sound deadening each person used for their:

1. Doors
2. The doors and trunk
3. Any other areas you may have done

Thanks

 

100 sq ft

 

the people who did just the doors/trunk area, did you notice a significant decrease in road noise? Did you guys apply one or multiple layers???

 

road noise doesn't really come from my door.

how many layers depends on thickness of the material. thin ones, i would use 3 layers.

 

if you want to get rid of road noise, deaden the cubby behind the seats... you basically humping the wheel well and thats where allot of noise comes from

 

You'll need some sort of closed foam cell barrier in order to cut down some road noise. I highly doubt dynamatting itself would do much for road noise.

And as for where to sound deaden. The whole interior if you got enough. Roof, Doors, Floors, Hatch, everything interior.

 

Anyone's who's driven without the passenger seat will hear a lot road noise permeating through the cabin floor. The Dynamat type stuff (Fatmat to be exact) doesn't really work for sound coming from my hatch, but it did wonders with rattles.

I went a different route for the floor:
I placed a couple layers of cell foam Edead v.4 Teklite (from Elemental designs) and my old z mat under the passenger seat. It's noticeably quieter and I have yet to do the driver's side.

 

Was wondering this, when driving it sounds like a "window" is open behind me. Especially during rain/wet roads. This is extremely annoying.

Was thinking of doing the hatch area just to cut down on noise.
Sounds like i need to reconsider and do the hump under the cubbies.

How they could release a car that is this noisy is beyond me.

Anyone who has done this step by step have an area that cut the noise the most noticebly? Looking to do it step by step. Read a pretty awesome review that someone posted on here about the different brands. Looking into the Rammat.

 

I'm in the same boat as some of you guys. I'm going to go for the challenge of doing this myself and hoping I don't totally F up my car.

Somebody said 100sq ft. Is that enough to do the rear all the way to the firewall?

This has been a good thread for me.

Do I just remove the 4 bolts on each corner of the door to remove it?

Thanks

 

This too.

That's what I did. Worked great. Others may have different opinions though...

 

2 cans of "spray in bedliner" from Pepboys. One can for each door. 2 sheets of generic dynomatt for the trunk, plus another can of "spray in bed liner"...

 

If you have a coupe, you need to put sound deadening in the rear cargo floor (paying special attention to the rear wheel wells which are inside the car and allow road noise to enter the car just as you experience with a stationwagon). You can use sound deadening sheets or spray-on solutions. Spray-on-rust-proofing products applied from the outside to your rear wheel wells also reduce road noise.

You also need to add sound deadening to the pedestal behind the driver/passenger seats. Sheets or rolls of sound-deadening work best here.

Sound deadening in the doors is mostly to prevent “rattling” from the speakers since there is little road noise that enters via the Z’s doors.

A complete solution adds sound deadening to the floor under the driver and passenger seat. This would be sheets, rolls, or spray-on products.


Or… you could buy a G35/37 coupe.
