Rear seat sound insulation part number

[Obioban]

Personally, I think dynamat gets way overused. It’s not sound insulation, it is heavy, and removing it is terrible.

nice! it's gotta be better than putting on dynamat. i've done it many times, and i just hate it lol

Yeah I'm the same as you - I could dynamat it, but then it's not a genuine solution, and also a lot of work. Dynamat isn't cheap anyway so I figured, like you, that it was the best option haha.

pulled the rear seat and the sound deadening was destroyed...thought about dynamat, but I hate doing that crap. found this thread and noticed there hasn't been an update yet...just ordered the part, will update you when it comes in...looks like a month

Thanks for this - the piece certainly looks to be very similar in material to the “759” part number. I think I'm going to order 759 and see how it works for me

Awesome, keep us posted. The 759 part is definitely the best option. What's appealing to me about the E90/E82 parts is that they'll be dirt cheap at a junkyard.

Well it sorta fits:



There's a raised portion in the middle that flattens out easily and some trimming is required for clearance around the seat back and belts. But overall fits pretty decent.

Also weighed in at 2 lbs, so slightly lighter than what realoem says. Will only get lighter after trimming

The E90 part might be a better choice - 51487058128. Hump in the middle is flatter and it looks bigger than the one from the E82, which is good since there's some trimming required anyway. Realoem says that one is 1.025 kg.

You should steal the one from your 128 to test fit on the M3

beat me to it!

Lol I knew that was coming. Haven't taken the rear seat apart in the E82, but don't think it should be too difficult. Might take a look later

That’s no small effort— both cars have a baby seat in the back.

Please update us, if you do!

The 759 looks like a very nice piece to be honest, good shape, but I have never seen it on a car.

Yeah it does, it looks to have liftable flaps so you can access the covers to get to the fuel pump, etc. seems to be nicely moulded. Shipping to NZ is painful cause of it's size so have reached out to a couple of places in country to see if I can get a reasonable price.
