Hate to resurrect an old tread. But used to race bikes and because of this have hearing damage. So I want performance without too much drama. Love to drive fast but want to be able to hear the person next to me. So.
Have any of you added back the door insulation that is not meant to be in the F87 doors?
I find that doors often transfer road noise from the exterior especially if there is little or no insulation..
Thanks!
