Well, I can share what I did:
- Popped off all the door panels and lined them with Dynamat Extreme.
- Lifted out the rear floor, removed the OEM pad, lined the underside of the floor panel with Dynamat Extreme, replaced the OEM pad, stapled everything down with trusty staple gun to supplement the adhesive.
- OEM has two weatherstrips around each door opening and there is a space between them. Cleaned the metal with alcohol and laid in 3M EPDM self-adhesive weatherstrip between the two, pretty much all the way around.
- Popped off the plastic covers at the base of the door strikes (the U-shaped things the door catches on when you close it), loosened up the torx bolts and moved each one closer to the vehicle interior, retightened.
Result is solid reduction in road noise and wind noise - as I said, well worth the time and cost.
Cost : $140 for the Dynamat (9 sheet bulk pack, Amazon), $75 for the 3M weatherstrip (3 packages at $25, Advance Auto Parts)
Disclaimers: 1) I am not any kind of expert in vehicle noise reduction. There appears to be a cult out there dedicated to the pursuit of total sound isolation, often connected to extreme sound system installations. From what I've seen, they're expert but nuts. I'm sure plenty of fault can be found with what I've chosen to do (didn't do enough, did the wrong things, used the wrong materials, etc.) by people who actually know something about this. Sorry 'bout that. 2) This is NOT what the BMW engineers decided you should have in an Ultimate Driving Machine, so I have sinned in doing this project. I will chant ten million times "I did not NEED to do this. No one NEEDS what OEM does not provide." as penance.
