Main benefit of adjustable LCA's vs. non-adjustable LCA's?

As per the subject, I'm looking at them, and other than the price, what is the major advantage adjustable LCA's have? I mean the founders LCA relocation brackets say they'll work with factory control arms in any of the positions, so why do I need an adjustable one?

I've searched the site here but can't come up with a clear answer as to why they're actually better.

Can anyone explain it in layman's terms?

They mostly help out with centering your rear axle housing and keep the rear tracking straight. Factory tolerances are not great and rear end can sit angled a tad in the car.

Also helps if your running bigger tires, you can move the rear axle in the body to fit your tires better with out rubbing the front of back of wheel well

I have the Founders brackets, the stock arms do not fit in the bottom holes, at least mine didn't.

Well, it seems, at least from the initial feedback, that the adjustable ones are the wya to go, just to be "on the safe side". I don't know that I'll use the bottom bracket, I do have Hotchkiss lowering springs so the car is lowered 1.5-2". Does it really make that much difference?

Adjustable lca's center aftrmarket rear ends..or like a 9" or something in the wheel well. And can help run larger tires.
As far as the relocation brackets you want to use the lowest hole to correct the lca angle that was altered by the lowering springs. Even if it wasnt lowered the lowest hole will increase foward bite and eliminate wheel hop. And an adjustable panhard it a must for lowering if you dont already have one.

Re: Main benefit of adjustable LCA's vs. non-adjustable LCA's?

None unless something else in your car is bent up, then you can use them to straighten the aligment, but that means you're moving something else out of whack to do it. Some use them to move the axle back or forward to get a little bit of extra clearance, but again it shouldn't really matter on an f-body unless you have something bent up (90's Impala's/caprices had the tires closer to one side of the wheel well so it would make a difference).

for the most part it's just easier to sell them because people think they need them. And for the most part, most people adjust them once and then never touch them until the adjustment comes loose (which wouldn't happen with non adjustable LCA's :-P )
