BRZ limited has factory installed sound proofing
 

For All Who Are Looking To Add Sound Proofing To Your BRZ. Here Is What I Found So Far In The BRZ.

doors: From The Factory, there Are Two Pieces Of CLD On The Outer Door Skin. One By The Speaker, The Other By The Door Handle. Each piece Is About 6X6 Inches. (I Added Two 12X6 CLD Tiles Above The Crash Bar And One 6X6 Tile By The Speaker.) There Is Nothing On The Inner Door Skin. The Inner Door Skin Has A Lot Of Metal Folds In It Does not Resonate Much.(I Did Not Add Anything To It). TheTrim Panel Has Nothing On It. (i Added a Layer Of MLV, A Layer Of 3M Thinsulate Acoustic 1/4 Inch Thick. And Filled The Spaces In The Door Trim With Thinsulate.)

Front Seat Foot Wells: There Is What Looks To Be Sound And Heat Insulation Here. Closed Cell Foam, 1/8 inch MLV?, styrofoam, And Jute. As We All Know, There is Room For Improvement Here. (I Added A Layer Of MLV From As High on The Heat Shield As I Could Get All The Way To The Front Mounting Point Of The Front seats. The Same Layer Went Up The Sides Of The Footwell From The Center Counsel Trim To The Door Sill.)

I Put A 39 inch By 19 Inch Piece Of MLV into The Back Seat. Added A Later Of Thinsulate Here As well. Overall, Not Bad. I Got A 6 dB Reduction In Noise At Peak 75 hZ At head Level Drivers Seat.This Is Driving At 70 Mph On Asphalt . Next I Plan To Add 30% Coverage CLD to The Trunk, Followed By MLV and thinsulate To The Rear Seat Bottoms.

Thanks! you got any pictures?

People are trying to make their BRZ quietER?!?:bellyroll:

The car is already way too quiet for a sports car:slap:

No Pictures, Sorry. I Was Rushing Through it. I Can Take Some When I Do The Trunk And Rear Seat Bottoms.

Just Trying To Share Some Info. Your Goals May Vary From Mine. For Me, This Is A Daily Driver. I Have A 100 Miles Per Day Of Commuting To Do And Lot Of That Time, I Am On The Phone With Clients.

Sorry About That, My Phone Does That On This Forum.

Theres two panels of that black tar crap in the footwells. One just in front of the seat and one just behind it. There's one on each side of the trans tunnel and on top of it. There's some half inch thick rubber backed foam that covers the whole trans tunnel. Theres a half inch thick firewall blanket too. Couple pounds of seam sealer under all that.

Very observant!:party0030:

Is That Really Tar? I Thought It May Be Vinyl. Either Way, No Need For CLD there.

then you should be driving a mercedes or lexus instead. Sorry you bought the wrong car.

I don't get this type of comment. Anyone can buy any car to do whatever pleases them with it. It's their money. He didn't buy the wrong car. He bought the car he wanted and is doing with it whatever it is he likes. No need for belittling comments.

Is it wrong to buy a car you love and use it as a daily + work?

OP is not complaining about the noise in the car; he's just sharing some useful information which may or may not benefit you and the community.

Smells like it when it's on fire :lol:
