Panhard bar setup.

This past week I had time off and put together a panhard bar setup that I was thinking about doing for a few weeks. I took some pictures of the final assembly minus the installed bar and finish welding.

Not bad work at all sir. Im glad you posted pics like this, I now have a better understanding of it and the install. Is this a track car for you by chance?
I cant stop looking at it, I like it alot haha.

Looks very similar to the one I built and installed a year ago. I used the same means to attach to the "frame rails".
What kind of rear end is that?

82transam 12-31-06 05:00 PM

Very cool, nice work. how are you attaching it to the frame, just bolts through those holes you have drilled on the C-channel or are you gonna weld it too?

mattp 12-31-06 05:31 PM

Thanks. It's not a track car really. Pretty much just a toy.

The rear is a Ford 8".

The holes are for welding so there will be more than just the edges along the rails. It's a little overkill. I still have to weld it all into place.

Is the geometry adjustable? Very nice work!

Ooops should look more first....deleted

Your panhard should be level when the car is at rest
Where your panhard crosses the center line of the car becomes your roll center, yours appears to be very high.

This bar must pivot for the suspension to operate................WARNING

I must be missing something in your comment. The bar itself has adjustable rod ends on both ends.

He obviously didn't look at all the pix. LOL!

steve84GS TII 12-31-06 07:31 PM

I was a little lost at first too.....

The black,welded bar in the last pics is a strut brace for the vertical mount on the right side of the car.At the bottom of that mount, are the holes for the jointed panhard which attaches to the mount welded to the axle.
The actual panhard is shown in the first couple pics(silver, w/Heims)

My bad, must be tired, dang....

2 questions. How far in each direction, side to side, do you expect the rearend to shift and would it be better to reverse it for clearance for the over axle exhaust?

3rd question, are you planning on going with a tri-link later on?

I can't remember the exact number, but it's small. The bar is almost 30 inches long. And the exhaust is good. I'm doing that next.

I might add a tri link.

***2 questions. How far in each direction, side to side, do you expect the rearend to shift***

Being that mattp said the Panhard bar is approx 30 inches long you could draw some lines at a 30 inch radius & get a fair idea of how little the chassis/rearend movement to each other is.

***and would it be better to reverse it for clearance for the over axle exhaust?**

The answer to this question is, yes you would have better clearance on the passenger side for the exhaust. The Panhard bar end that mounts to the chassis should be determined IMHJ (because of changing roll center height) by doing an analysis of the tracks you run if the car is a track car. On a strreet only car I would mount the chassis bracket to the drivers side of the car. More clearance for the exhaust on the passengers side.

The G-Force Tri-link is a nice piece.

Have Fun

I think if I had an off the shelf exhaust or there would most likely be a clearance issue, but I've made my own and worked on it along side the panhard bar to make sure things would clear. I actually think exhaust clearance would have been a little more tricky if it were switched.

It's all quite circumstantial anyway.

David Dewhurst 01-01-07 07:39 PM

***I actually think exhaust clearance would have been a little more tricky if it were switched. ***

mattp, I have a three inch over the axle with the Panhard bar chasis mounting on the drivers side.

Whatever serves the persons need.

mattp 01-01-07 07:44 PM

I do too. Fifty ways to skin a cat.

David Dewhurst 01-02-07 09:03 AM

*** Fifty ways to skin a cat.***

If you want to play upsmen ship there is a reason on an ITA race car why the Panhard bar attaches to the chassis on the drivers side or the passengers side. With that said there are not Fifty ways to skin the cat.

very nice work matt.

please fly out to southern california and build one for my REPU! ;0
