We would appreciate if all reviews and install pics could also be posted on our Amazon listings found here: GT Sound Control @ Amazon.com:.

We are trying to build up the brand name.


Still offering the free samples if anyone else wants to try it out!

Its best to remove the plastic rear hatch side panels that cover the shock towers in order to reduce unwanted noise entering the cabin.

First, the rear hatch rubber gasket needs to be pulled up to the top of these plastic side panels before these plastic panels can be removed. Next, the 4 plastic tie down clips need to be removed by inserting a standard blade screwdriver in the clip slots.

Second, the rear hatch plastic panel clips need to be removed before the rear hatch side panels and its clips can be remove. The rear hatch light need to be disconneted.

Third, the rear hatch side panels clips need to be removed.

Once all these rear hatch plastic panels are removed, the foam piece located in front of the space tire well can be removed so the sound deadening material can be installed on the steel car frame.

The other area of the 370Z that transfers noise into the cabin is the doors. The best way is to removed the door interior panels and remove the access panel in order to gain access the the back side of the door skins. This is time consuming and involves disconnecting the window motors and can have issues with the window tracks and window motors.

I would suggest reviewing the 370Z service manual that can be downloaded from this web site prior to removing the plastic panels. Also, a plastic panel removal tool is a must to prevent damage to the plastic panels.

Good luck!

So my review on the sound control is as follows. I have managed to eliminate some road noise! At slow speeds I can tell a difference in the road noise coming from the back of the car. I didn't cover the entire hatch/trunk area so I'm not expecting a drastic change but for 10sq feet of product it did quiet things down considerably back there. The bass sounds about the same, the one rattle I had(unknown where it was coming from) is no longer there so I'm happy! A weird side note, I feel like my exhaust sounds deeper now? When I downshift, the rev match throttle blip sounds slightly deeper. That could be all be in my head. Anyway great product, great bang for the buck as well judging by your Amazon listings!

I'm looking forward to driving once the process is complete (if it ever stops raining), and from reading the opinions of others who already installed their sample, it seems likely I'll be purchasing more to finish the car.
