another panhard bar thread

[01MaroIL]

ok i searched a little to decide whether or not to buy and adjustable or non. Ofcourse i read that it is reccommended that you get an adjustable one if you lower your car. but i also found someone that said...

You don't need an adj. rod unless you plan on running larger tires or drag radials. Hope this helps.

So what is valid info and what isnt?

Do you need an adjustable PHR if you lower your car or can you get by with a non adjustable one?
I plan on lowering my car, but i dont plan on running drag radials.

Thanks

You do not NEED an adjustable.

You MIGHT if you find that after lowering AND wider tires the wheel well clearance is too tight.

As with all suspension mods, it helps a great deal if you understand what's going on, instead of taking some unknowns word from the Web, which is often downright dangerous.

The Panhard is attached to your rear axle at one end and your chassis at the other. Stock, it is roughly paralell to the ground. Lower the car and the two mounting points move a bit farther apart. So the constant length Panhard pulls the body a bit off center to the axle. This can cause tires to rub.

Because your Panhard is now at an angle to the ground, it also cranks a bit of "wedge" into your car. That means it will handle a bit differently in right and left handers. The adjustable Panhatd can center the body and fix the rub. It does nothing for the wedge.

Panhard relocation brackets may be able to fix the wedge. Is that important? Beats me.

There are also angle considerations for your LCAs, and relocation brackets for those also.

Lowering a car is really a messy thing with regard to suspension geometry.

Here's my story of my panhard bar.


I had stock steelies and rubber on my car, bought
17x9.5 rims with 275/40/17 rubber.

Mount it up, it was rubbing ALL over the right bumpstop, so I put the stocks back on;

I used a plum bob and measure that my rear was like 3/8" shifted to the left?!?!

So I got an adjustable panhard bar, put the new tires in, let it sit, adjust it so equal disantces on each side...

GOT AN ALIGNMENT!!!

So I really couldn't have put the rims and rubber in without the adjustable panhard bar, in my case at least.
