[MG ZS STE]

i stuck 2 layers of flash band on all door skins and the roof, filled the A,B & C pillars with expanding foam. Made a big difference, especially on motorways where i was always conscious of a ringing resonating noise all around me. the missus thought i was going mad but i knew it was there. Stereo even sounds better now.

Give your roof and doors a tap and then tap the neighbors mondeo or vectra and you'l hear the difference. mine sounds like your tapping on plastic now instead of flimsy thin metal.
