Over the last few weekends I decide to start a new project on the BRZ, sound deadening. Recently during the last 6 months I've started to get feed up of the amount of road noise that gets feed into the cabin. So in an attempt to tackle this I did some research on the various 86 forums and came across the following guide: http://www.ft86club.com/forums/showthread.php?t=53511. Using that guide as a base I bought some sound deadening materials from Amazon and went about installing it all.  Materials used: Silent Coat tiles - https://www.amazon.co.uk/Silent-Coat-187x265mm-Deadening-Proofing/dp/B00NVE013I/ Dodo Pro Barrier MLV - https://www.amazon.co.uk/Dodo-Mat-Barrier-Proofing-Camper/dp/B00LUOQWDY/ Silent Coat absorber foam: https://www.amazon.co.uk/Silent-Coat-Sound-Absorber-Proofing/dp/B00CV0BM0O/  Sound deadening insulation  Over the next couple of posts will be various pictures of the install. I decided to start with one of the most difficult jobs of the lot, the roof. Followed by the rear wheel arches.  Roof Install - Headlining removed Silent Coat tiles added Additional sound deadening insulation material Head lining re-installed. Rear Wheel Arches: Silent Coat tiles applied Sound deadening insulation material filling the remaining gap Dodomat Pro MLV added to rear quarter panels   This has definitely helped as it moved the noise from the back of the cabin more towards the front, it's still to noisy though, on the next step.
