I did a complete sound deadening installation on my BRZ. Used CLD tiles, mass loaded vinyl, closed cell foam, and extruded butyl rope from Sound Deadener Showdown. I took a ton of pictures along the way. Hopefully this serves as a good resource for anyone else installing sound deadening, or for anyone who wants to take their interior apart.
I ended up using approximately 80 sq ft of MLV (minus scraps, so probably 70 lbs into the car), 45 CLD tiles, 25 sq ft of 3M Thinsulate Acoustic, and 4 sheets of closed cell foam.
For tools, you need a socket set (10mm for the rear seats, something bigger that I can't remember for the seatbelts, an E10 torx socket for the seats (Harbor Freight has a nice cheap set)), a Philips screwdriver, and a set of panel removal tools.
It's not quite a step-by-step guide, but I took a ton of pictures along the way, and I'll try to write out descriptions as I get a chance.
