1990-1993 Porsche 911 Coupe Door Kit

The 911 door contains no sound deadening or insulation material. This is why your door rattles or vibrates when you shut it. HushMat has packaged the lightweight sound deadening and thermal insulation material to eliminate this cheap sounding rattle and vibration. A HushMat treated door slam is solid. You will experience the HushMat difference every time you open and close your 911 door.
