Where To Drill Hole For Front Adj Sways

[North Coast Cab]

Trying to install my new Tarett front sway bars. I need to drill the holes through the wheel wells since my car has never had a through body sway bar. There are no instructions providing direction on this part. Does anyone have a picture from the inside of the trunk showing the location? On the drivers side it's very tight with the gas tank nozzle and the brake master cylinder.

Thanks, John

Have you read this?

I was lucky I guess, my '84 already had this done.

Yes I saw that article, but it doesn't have a good view from inside the trunk area. This is where I'm thinking of going. Input?

John,

The bar should go under that shelf and behind the gas tank. Is there a stamping (impression) on the outside of the tub in the fender well ? I haven't looked at my Carrera lately, but my 76 has the indentation where one would cut a hole for the bushing/bar.

The normal position for the sway bar doesn’t go threw the trunk. It goes behind the gas under the trunk space.

There should be a triagular impression/marked area that you should be able to see from the wheel well area.

On my '84 you can just see the cross bar between the gas tank and the car body. You have to look through the gap with a flashlight so... I'm thinking you are way off(high). I read that there should be a residual/legacy impression stamped into the sheetmetal where it used to be drilled, its just not drilled anymore...

[chrisp]

if I recall correctly form when I did my Weltmeister, there's a vestigial imprint in the inner fender/trunk wall where the factory installed the through body bar in older cars.

Location is between the tank and the bulkhead that the steering rack resides behind. This puts it almost out of sight. In your picture it would be about 4-5" directly under where you have it now (under the lip that comes off of the flat area of the trunk and curves forward on each side to match the contours of the trunk).

Tim is correct, for the stock bar. But the Tarret, which I believe is similar (identical?) to my Kokoln must go through the inner fender. It goes through lower than your photo shows, actually below the luggage floor and behind the tank. I believe there are stamping marks on the inner fender. But in any case be VERY sure before you drill.

My old '88 had a spot that you could see from the fenderwell where there was clearly a stamp in the sheetmetal for the hole.

Thom, aka widbody911,
here on Pelican has a good pictorial of the install. here is a link to his web page: Look for Porsche 911 on the bottom left side. He has lots of projects listed. Look for the TRG sway bar instal.

Aaahhhhhhh!

One other thing to note -- I removed the gas tank when I upgraded the bars on my '72. Mine already had a through-the-body sway bar, but the holes had to be enlarged and reinforced.

911s equipped an under-chassis sway bar usually need sheet metal reinforcement when changing over to a through-chassis sway bar. In the archives, you'll see some pics of torn sheet metal on a Carrera. I think TRE carries reinforcement sheets. I also remember seeing a sheet metal pattern for a DIY install.

I've done this twice. The first time, the bar ripped through my fenderwall (I was wondering why my car was handling funny the last couple of laps at MidOhio). When I repaired it, I used the template shown above and had 1/8 steel added with the SmartRacing bar. I'm not sure why it ripped the first time, but its been fine ever since. The SmartRacing bar required the gas tank be pulled.

Here is a pic of the damage before repair. Chaulk it up to a heavier late 80's car, sticky track tires, and a large sway bar I guess. You can see, that metal isn't very thick there at all!!

[Tyson Schmidt]

That pic above shows that you had the bar adjusted way too tight.

What happens is that the arm becomes too short to allow full suspension travel. Once the arm is either fully straight up, or fully straight down, it's acting as a suspension stop. If the suspension still wants to go further, it will rip the mount out of the chassis like it did there.

[89911]

It was tight. The drop link wasn't as tight as it shows in the picture. Those were AJUSA bars that were prone to the slider moving. It must of came loose and slid to the center causing the tear. Junky components none the less.

[Bill in OKC]

I have a question I've been meaning to ask and this might be a good place for it. It appears that my front through-body sway bar is offset to one side. Is this normal? Is there something that keeps it positioned between the wheelwells and keeps it from moving left-to-right? It is a Weltmeister Thanks.

One thing to note, I Just now finished installing a SRP 31 bar. IF you are putting a bar that big in, I suggest mounting the bar as far rearwards as possible. The 22mm (25.4) Tarett bar fit no problem with the hole centered, but I had to do a little "bodywork" on the fuel tank to clear the big SRP bar.....
