HOWTO: Install Shark Racing 2010-2012 Genesis Coupe DIY Soundproofing Kit

I've read lots of comments about this kit. Some say it's great, some say it's awful. Some say the pieces fit well, some say they fit horribly. The one thing everyone agrees on is that they come with NO instructions. And therein lies the problem.

I have the kit installed now, and I can assure you that it fits 100% perfectly, and works as well as--if not better than--described. Without adding any significant weight to your car, road noise will be reduced, and your stereo will sound better.

So, here's a HOWTO. As with all HOWTOs, I am providing this only in an attempt to be helpful. Use common sense, because if you break something, it's not my fault, and I cannot be held accountable. =)

SUPPLIES

First, you can order the kit here. Shark Racing

Note that when you place the order, which is $180 at the time of this writing, you can upgrade to get the kit with the fender pieces for an additional $50, raising the price to $230. However, the kit comes w/ a hood liner. 2.0T models don't have a factory hood liner to which you could mount the soundproofing material; as I understand it, the US 3.8 models don't either. I emailed the company and asked them if they'd include the fender liners instead of the hood liner for the original price of $180. They said they would. I placed my order, made a note referring to our conversation, and they did as I requested. Since I neither ordered nor received a hood liner, this HOWTO will not include instructions on how to install one.

So, the pieces that I received were the following:

Door (Driver)
Door (Passenger)
Trunk (Hatch)
Trunk (Floor)
Fender Liner (Driver)
Fender Liner (Passenger)

The only other supply you will need is some kind of adhesive spray. I used 3M Super 77 spray.

TOOLS

You only need 3 tools for this project.

1) A plastic fastener removal tool.

Image


2) A Philips screwdriver

Image


3) A Dora the Explorer blanket.*

* I suppose any blanket will do. But if you COULD use a Dora blanket, why wouldn't you?

INSTALLATION

Doors

Remove the door panels completely. There are many HOWTOs on this step. You do need to remove the door panel completely. That means after popping out all 10 pop-connectors, you'll need to unscrew the door handle/lock mechanism. That piece looks like this:

Image


You only need to remove ONE big screw (the one shown in the preceding picture) and TWO small screws. They are pictured below. (One screw is hidden behind the white cable; the other is clearly visible.)

Image


Once you remove it, your door will look like this:

Image


THIS IS IMPORTANT. The soundproofing liner goes on the backside of the door panel itself, NOT on the door. See below:

Image


Apply the adhesive spray to the soundproofing material, then apply the soundproofing material to the door panel. It's sticky, but allows for repositioning, if you do it quickly.

Note the various plugs that you'll need to reconnect. There are openings for these plugs in the soundproofing material. Reinstall the handle/latch, reconnect the plugs, then reinstall the door panel.

Repeat for the other side.


Trunk Hatch

The trunk hatch trim piece has 10 connectors you'll need to pop out using a plastic fastener removal tool (aka door upholstery remover, etc.) Once you pop all 10, the trim/carpet piece will come out. Simply place the soundproofing material on it and use the adhesive. NOTE: Make sure you orient the piece correctly. If you have it mirror-flipped, the latch opening will appear to be 2-3 inches offset. Simply mirror-flip the piece, and it should line up perfectly. When you are happy with the alignment, apply the spray adhesive, then reinstall the trim piece.

Image


Trunk Floor

This piece is one people sometimes complain about being poorly made. Invariably, they have tried to install the piece in the wheel well. It doesn't go there; it goes on the underside of the trunk carpet. Note that the trunk floor piece is a mirror image of itself, so you can't mirror-flip it the wrong way.

Original piece:

Back side with soundproofing material adhered using the 3M Super 77 adhesive spray.

Fender Liners

These take some time, but like the other pieces are straight forward. Note that the fender liners are exactly the same, whether they go on the driver's side or the passenger's side, so you can't get it wrong.

Jack up the car in the front and remove the front tire. NOTE: Always use a jack stand in addition to a jack when jacking up a car and working under or around it.

Using your philips screwdriver, remove all plastic fasteners and screws from the plastic fender liner.

Your car will look like this:

Image


Your fender liner will look like this:

Image


You need to clean all the dirt off of the fender liner and make sure that it's dry. Apply the adhesive spray to the back of one of the soundproofing fender liners and apply it to the plastic fender liner. The result will look like this:

Image


Reinstall the fender liner using the plastic fasteners and screws.

Repeat for the other side.

That's it! All that's left is to clean up your mess, put away your tools, fold and put away your Dora blanket, and enjoy your much-quieter car!

I'd like to say thank you for doing this. I was putting off ordering this just because of the mixed reviews but now I see the mixups. Plus I like that they let you swap the pieces which I'll most definitely do. Well done sir. Now go to bed with your Dora blankie.

great write up!

Thanks for the write up!!

I will probably be doing this in the future.

One question though, How much is the total weight added for this?
 
#12 ·
Seems like some of these panels could get wet (fenders) in normal use. Anyone experience this?

Thanks for the write-up. Don't I feel like a dumbass for mounting the fender liners under my hood? I'll try and redo it for sure.

I can't beleive the people that sell this can't be bothered to snap 4 photos of the kit being instaled correctly and include it w/ every purchase. That's pretty lame.

The fault is totally theirs, not yours. Two things helped me figure out how the fender liners went on. For one, it kind of fit with the theme of the pad always fitting on the back side of the existing trim. You didn't have any trunk carpet/trim, so the pattern wasn't really there for you to figure out. The second is that I recently had one of the fender liners on my son's Tiburon off so I could run a power wire to his amp, so the shape of it was fresh in my memory.

It is amazing they don't provide any sort of instructions whatsoever. It's obviously not 100% intuitive. I may try to clean up my HOWTO a bit and offer it to them to include in future packages, as JewishThunder suggests. =)

Nice write up. I would consider a kit like this, but then that would just accentuate all the god damn dash, headliner/sunroof, and seat belt/seat noises/rattles/squeaks which drive me insane on a daily basis.
 
#19 ·
You know I was never interested into sound proofing my car however this write-up alone, single handedly, by yourself, 1 car, 1 blanket changes my mind. I'd definitely look into this now. Good Job man !

Jonahan:

I guess I am a bit confused. I don't know much about car noise sources, but it would seem like interior noise from wheel wells would be mostly from the REAR wheels since they are closer to the passenger compartment than the fronts. So I would think the
fender liner insulation would be better placed on the REAR liners. Does the trunk (top and bottom) insulation in this kit sufficiently deaden the rear wheel well noise, or should you expect to also add some home-made insulation to the rear fender liners?
 
#25 ·
The rear fender liners aren't as big as the front ones. They only cover the back portion of the wheel well.

I think alot or the noise from the rear is because it's hitting the sheet metal which isn't very thick there. My opinion to fix it would be to get some mass loaded butyl rubber sound deadener and to rip out the interior and stick it on the inside of the fender well.

So a quick addendum to this because I am doing it as I type. The doors you don't have to take a screw off for the handle. The black part has a little clip that you can just pop out and boom its off. Otherwise. this is perfect!
 
#27 ·
Also, for those of us lucky enough to have the handle on the inside of our trunk hatch. Pop that sucker open with a panel popper and it's two screws on the inside.

My stuff came in today. Too bad I'm stuck at work on a boat and can't install it for another 3 weeks. ;/

With my flippy flops!!!

Great write up!
 
#30 ·
Nice write up, do you have factory tunes in your car? I see you said better sound quality, you mean clairity?
 
#31 ·
I can sort of chime in on this. I really think that my stock system sounds noticeably more crisp and clear.
 
#32 ·
how did this hold up to road noise and vibrations from the engine bay?
i have the 50 durameter CP-e mounts and was thinking of maybe going this route to help with the vibrations a little., ive fixed all the interior vibrations and noises but there still some i get thru the steering wheel. no much but i know its there.
 
#33 ·
Honestly I doubt you'll get any relief from the motor mount vibrations with this kit. You need to get your rotating assembly balanced.
 
#34 ·
oh yea? didnt think i had to get it rebalanced for motor mounts. ill look into it.
 
#35 ·
That's just the reason you get so much vibration. My last built motor I had almost solid mounts and it shook the car so bad that my glove box would routinely wiggle open. I got it built and balanced and put it on the same mounts and it hummed like a BMW. I've been in built and balanced cobras on solid mounts that don't vibrate as much as our stock engines do on 50-60 duro poly mounts.
 
#36 ·
word, im probably going to take them out and put in the stock mounts till i get the motor built/blanaced. would be nice to have it all said and done. i want the bmw hum lol
 
#37 ·
Got around to installing mine today, minus wheel well liner which I'll do when I get new wheels. Only problem I had with it was there were no holes for the trunk hatch handle screws, but that was easily fixed. Haven't driven anywhere yet, but just revved it up in the garage and the exhaust drone is almost non-existent now. Which is quite amazing since injen has a terrible drone, lol.

Posted this in a few other threads
"Would anyone who has installed the shark racing pads for some time now be able to give us an update on how they are holding up. I'm worried the wheel wells will get water logged and get moldy with time."
 
#39 ·
The only way anyone would know is if they removed the wheel well liner and looked. That's probably not gonna happen =)

If properly installed, it'd be really hard for them to get waterlogged, though. Sorry I can't answer your question. I don't even have mine anymore since I traded in my '10 for a '13 and didn't redo the install since the '13 is much quieter from the get-go.
