Dodgy Sound Deadening your doors

[TbM]

Thanks for the extra info RAD, im just a diy'er so dunno the best way to do things lol.

I forgot to mention cutting slits to let air pockets out ill update the diy when i get a chance, thanks for that.

I did mention you can use less dynamat i just like to overdo things

My trusion bars were attached quite well to the panel so i let them be, the braces on my roof were a bit loose tho so i sikaflexed them to the roof skin while i was dynamatting the roof.

As Trism has said, deadening the doors is mainly for the speakers, if your trying to reduce road noise you can use the dynapad hes recommended and you can also deaden the wheel archs with brush on deadener, ive deadened the archs on my car and it helped alot.

What's that stuff and where can we get it? CL9 has plastic arches though, would that matter?

Its called brush on body deadener and i got it from supercheap auto, was about $30 for a tin i think



Mine has plastic there too, you just take the arch cover off and there should be metal there, i only did the rear part of the front arch as the rest of the arch is in the enginebay so no need to reduce road noise in your engine bay, i fully coated the rear arches.
Heres a pic to show the arch liner after ive put it back over the deadened arch.

ohh, you did the front as well....

front wheel arch isn't directly joined to interior though....

not sure about that, on the ek it looks like it gets pretty close towards the bottem rear of the front arch so i just gave it a couple of coats, had plenty of deadener and dont care about adding weight so thought why not. Sounds like its made a difference to the road noise from the front tyres.

Very impressive DIY here. The amount of photos really helps those who want to try it

Im not 100% sure either was pretty tired when i was doing it lol, did seem pretty close iirc. even if its not connected i probably would of done it anyway cause i tend to over do things.

Yeh as far as im aware the main parts to do are the ones that are incontact with the interior, i fully did the rear arch and just the rear half of the front arch
