I don't think this is a thing that most M2C owners are experiencing. I live in Los Gatos, CA. The many miles on major highways have very rough surfaces. The road noise is terrible at highway speeds. On good highway surfaces things are fine. Has anyone dealt with lowering road noise on M2C?

Thanks a lot your link provides me enough information.

To expand on your suggestion, beside the main sounded deadening, there is a specific door seal only on diesel and 4 cylinders 2 series' that also help reduce road notice.

Haha so true. I'm in Campbell, the roads up here suck.

part numbers:

Left side part- #51-48-7-348-779
Right side part- #51-48-7-348-780

anyone have these on their M2?

Campbell and Los Gatos are right next to each other and we share Highway. 17 from San Jose to Los Gatos several miles of mind rattling noise.

Same experience here. If there aren't other cars immediately around you, try to ride slightly off center in the lane and you'll notice a significant reduction in noise. I'm also noticing the noise becomes a little louder as the front tires wear out.

lol, that thread was entertaining; I agreed with so many points.

Why put sound deadening BACK into a performance car; that defeats part of the point of a sports car.

Yeah, even driving around town on decent roads, there is considerable wind, road, and engine noise. So much so that I dont bother with the radio, because its hard to hear it properly and cranking it up takes away from the M2's sweet roaring. I kinda expected this, so it is normal I'd say

[Montaver]

There M2C certainly feels less refined than my E90 M3. Ordered these parts from ECS, worth a shot. Not sure why adding them in would defeat the point of a sports car, if anything it will make the car more flexible and less fatiguing on long journeys with no detriment when driving spiritedly. Might also help the truly awful stock sound system slightly. I like hearing engine/exhaust sounds not tyre roar and wind noise.

I bought these and put them on my Comp, and they cut down the road and engine noise by a good margin. Could give it a shot. $14 each, plus shipping, definitely recommend them.

Don't get it twisted, the M2 is not exactly a Murcielago, it's primarily a street car with a sporty demeanor.

Eliminating the sound deadening is a cheap trick for the user to misinterpret road noise as performance and also, it reduces cost.

Hearing a bit of road and engine noise allows a driver to feel more connected with the car on the road. My M235i was numb compared to my M2C. I couldn't hear the engine to know when to shift the paddle shifters in manual mode. I think the lack of hood insulation allows the engine sound to come through. I have no problem hearing when to shift my M2C 6MT.

You always have the option of putting the windows up or down, if you desire more cacophony..

BTW, kudos on discovering that missing door seal, ages ago..

I mean to each their own; I've been primarily driving luxury cars most of my life, so the whole dead-quiet aspect while I drive thing is just.....boring to me.

I feel an M2C wouldn't be as fun with sound insulation; when I drive in Comfort Mode with the windows rolled up, it's already quiet as a mouse to me.

You know, you can still clearly hear the engine and exhaust with some sound deadening, it doesn't automatically transform your vehicle into electric-car like tomb.

At least if it's reasonable docile inside, you have the option of making a phone call or having a conversation with a passenger, without interruption and cracking the window or sunroof, when you want more fanfare.

My old Mini Cooper JCW had no sounded deadening and I could of never properly use the Bluetooth speaker because the engine sound would be a distraction the person on the other line. It's was so annoying and one of the reasons I was happy to get rid of it.

However, if you're the type that lives his life a quarter mile at a time, I could see why would appreciate no insulation and probably the first to use some dry ice to delaminate all the factory undercoating.

That is one reason that I drove my M235i with the sunroof open as much as possible.
I inserted a pic on the first page of that weatherstrip thread that shows my new and improved addition to the wind whistle cure on my M2C. 😉

I get what you're saying, but my point is, the M2C just isn't that bad when it comes to road noise.

I definitely would not want a car that would have ALL sound deadening removed (I'm not a masochist, lol); maybe it's just a personal experience thing- I've driven my M2C on buttery smooth roads to less than stellar roads, and to me, it isn't something that would require me to actively seek out additional sound deadening.

That said, I drove my friends Honda Fit several times - THAT has very bad road noise.

Fitting these side trims can reduce airflow ie hot air extraction - from under the hood - less of an issue in winter but maybe more of an issue in warmer months...

[AlpsRider]

Perhaps that's true. However the kind of heat generated by this engine I would think is primarily cooled by the radiators located behind the front grill and less by an air gap at the fender corners at the rear of the engine.
