Hey guys,

Just wondering whos used sound deadening in there skyline!

Im getting my doors done but where else have you found to have a noticeable impact on cabin noise.

I have a Series 2 Gts-t coupe.

Thanks!

I have put dynamat extreme on a few ee series 2's, if you do it properly, i.e. on the inner and outer door sheet metal, you cant go wrong. It will make your doors sound firmer, as well as make your door speakers sound awesome. To give you an idea, the pioneer splits in my doors put out more bass than the kenwood 6x9s which I have mounted in an MDF parcel shelf.

*sigh* still to do mine. I have a Dynamat extreme kit, so it should do two doors.

Anyway.. my boot rattles with a single sub. I thought it might be the keylock part, which has some play in it... in which case I might just lather it in some thick grease instead. (from the inside of the boot-lid.. behind the lining if you have it)

under the rear seats is a source of noise.

the doors give you the best bang for your buck but if you have time and money that is the next place to get stuck into.

Rear quaters/doors if 4door and boot are both good places to SD. I had a bare boot and after SDing the boot bottom and wheel arches it made a fair bit of difference.

So it is quite good to do eh?

Seems a few people are getting tighter panels and increased dB from doing the doors and boot.

yep, fixes a few things - lack of bass for one in the doors.

this is one of those how long is a piece of string questions, but roughly how much weight are we adding to just the front doors? 5kg?

I'll say this - a bulk pack (9 sheets) is 18kg. do the math off that. doors on a skyline takes 4 sheets.

Say chris.. do you reckon the dynamat packs are worth the money in your opinion? because, i've got a boat load of deadening packs i bought from a car shop years ago (it's basically just adhesive with some foam). and i've also got a few litres of septone brush on deadener (which smells like fish oil, but seems to work well on my boot). but then again, they're all available to me at no cost... whereas a decent deadening pack to do my doors, floor, boot will set me back a few hundred.

I got the dynamat bulk pack off ebay for about $200, off quicksmarttechnology i think there name was. I did my doors and I have plenty left over to do my boot. From what I have seen and heard, the brush on stuff can be a pain and pretty messy, dynamat is pretty much like putting contact on your doors (not really as easy)

may want to do the math here but its $248 shipped. now I do these things at $243 shipped all day long. postage is not $39 to ship it oz wide- its roughly half that.

that said its application is pretty much like contact paper only a bit thicker.

howie,

if you haev access to teh foam type do it. the spray on is messsy and not as effective. good for rust though.

      After market rear camber arm adjustment

      By Duncan · Posted

      Then, shorten them by 1cm, drop the car back down and have a visual look (or even better, use a spirit level across the wheel to see if you have less camber than before. You still want something like 1.5 for road use. Alternatively, if you have adjustable rear ride height (I assume you do if you have extreme camber wear), raise the suspension back to standard height until you can get it all aligned properly. Finally, keep in mind that wear on the inside of the tyre can be for incorrect toe, not just camber

      I know I have to get a wheel alignment but until then I just need to bring the rear tyres in a bit they're wearing to the belt on the inside and brand new on the outside edge. I did shorten the arms a bit but got it wrong now after a few klms the Slip and VDC lights come on. I'd just like to get it to a point where I can drive for another week or two before getting an alignment. I've had to pay a lot of other stuff recently so doing it myself is my only option

      You just need a wheel alignment after, so just set them to the same as current and drive to the shop. As there are 2 upper links it may also be worth adding adjustable upper front links at the same time; these reduce bump steer when you move the camber (note that setting those correctly takes a lot longer as you have to recheck the camber at each length of the toe arm, through a range of movement, so you could just ignore that unless the handling becomes unpredictable)

      I got adjustable after market rear camber arm to replace the stock one's because got sick of having to buy new rear tyres every few months. Can anyone please let me know what the best adjustment length would be. I don't have the old ones anymore to get measurements. I'm guessing the stock measurement minus a few mm would do it. Please any help on replacing them would be fantastic I've watched the YouTube clips but no-one talks about how long to set the camber arm to.

      Heh. I copied the link to the video direct, instead of the thread I mentioned. But the video is the main value content anyway. Otherwise, yes, in Europe, surely you'd be expected to buy local. Being whichever flavour of Michelin, Continental or Pirelli suits your usage model.
