BMW E28: Kilmat Install (Sound Deadening)

This mf car is just too loud for my current vision of where I want this car to be. The Kilmat (80mil) sound deadening definitely helped with exhaust noise in the cabin but I realize that the interior volume is mainly due to the wind noise, so I gotta fix that soon.
I'm going to install the Kilmat in other areas in the car, so hopefully that will help even more.

#1 source of noise in the E28 is wind. Mass loading isn’t really effective until ALL seals are replaced. And since the door seals are not full circles it will never be as quiet as an E23

Where did you buy the mats?
