How's it going to fling? The rotor hat sits flush with the back of the wheel-- nowhere for it to go.

Why the hood sound insulating pad?

Because I'd like the car to be a bit quieter.

I've also got the trunk and side sound insulating panels as well as the big metal parts that go over the open holes above the rear wheels, but that's an entirely different project.

Fly - I had seen your post where you had listed the parts, which was very useful. However, I couldn't tell which parts are the ones that go in between the doors and the front fenders. I think its like a strip that goes in the door hinge area. Others have said that was the most effective in sound reduction? Could you post those part numbers along with the hood insulation parts? Did you notice any noise reduction with the hood insulation?

Thanks

Thank you. Have you installed these, and whats your take on the reduction achieved? Also do the fender body seals have tape on them to adhere to the panel?

So far, I've only installed the fender seals (although I have all the other insulation bits to try out at some point as well)

They do provide a slight reduction in noise (primarily from the tires/road)

It's not a huge difference but definitely noticeable

They do not have any tape on them

They basically get wedged between the fender and the body

If installed properly they do not require any tape or adhesive

The only potential drawback I see to installing them (especially since I track my car) is that they may trap some heat in the engine compartment (which is also why I haven't yet installed the hood insulation)

Thanks, what change did you notice with the hood insulation?

Very helpful. Thanks!

I don't see how the under hood sound insulation traps any meaningful heat, when it comes standard on all M5s and above.

I honesty believe it was omitted on the M2 to give it a sportier sound, i.e. a mixture of injector ticking and intake charge noise...

Also, you guys with M2Cs, keep in mind that you're using the hood insulation part from a F22 M235i, which has a slightly different shaped hood than the Competition model, since it has to accommodate the top mounted intercooler, the M235i/M2 doesn't.

Not sure if the hood insulation from the M235i would fit precisely on Competition, due to this fact.

I guess I'm not understanding what you meant. I understood you were going to spray Cosmoline RP-342 on the inside of the rotors (vents)

Well, the hood insulation is pretty thick and is close to the equivalent of putting a blanket on top of your engine

Nevertheless, like you said, it probably won't make a significant difference

In the center of the rotor hat-- where the center nut and cotter pin are.

Installed E9x Clutch Slave.

Now it's much easier to locate the clutch point, and yes the pedal effort is lighter (Stock E9x). Along with the ASD delete (fake engine noise removal), the AutoSolutions shifter with 80A PU bushings, my car has regained all the non-modern car noises and gear whine

gotcha, I cleaned mine out and put some rust inhibitor on it as well

Had to take my M2 for a nice drive. The battery was so low that the alarm flasher stopped working. Nice that it started up on the first try though. It is hard on these cars sitting around when they are use to being driven daily.

Took her in for the second service, oil change and check over. Also had some interior rattles resolved and the brake rotors warrantied.

Rattles were coming from the two speaker covers behind the rear headrests. Removed the covers and added some felt tape around the edges. Silence👌🏻

What do you mean you had brake rotors warrantied?

*Replaced under warranty* they were shot and it was shaking like hell when braking. Garbage iron rotors.
