What's the advantage of adjustable rear lower control arms?

[integraXTC]

I'm considering getting some lca's, but don't know if the adjustable is that much better, or how do I know what a good adjustment is?

When you adjust them, what does that do? Lengthen the lca?

Correct me if I'm wrong but it allows you correct the rear suspension camber settings. Camber is the inward or outward tilt at the top of the rear wheels and tires on the car.

[integraXTC]

that seems to make sense, as lca's are meant to gain traction.

And if you're right, then I'm pretty sure I'm going to be needing a camber correction, as my summer tires are heavily wasted on the insides (if I recall correctly).

Anyone else?

The only thing I have ever adjusted them for was when running a larger tire, it allows you to recenter the tire in the wheel well.

The aftermarket LCA's gain traction simply by stiffening the entire link. This decreases flex and energy loss which transfers the energy to the tire more directly. This will dramatically help with wheel hop. The bushing is the key also. Removing the stock rubber and the flexible stamped OEM lca's is the only reason to swap them out.

In my opinion, the LCA's have nothing to do with camber. Especially when there is a solid axle and no camber adjustment on the rear.

They allow you to make the rear end straight in the car as well as locate it forward or back for tires. An adjustable PHB allows you to center the rear in the car (left/ right). You will want an adjustable TA if you legnthen the LCA much at all you can potentially change your pinion angle as well. With adjustable LCA's you can make minor changes if the car pulls or dogtracks. Sort of like being able to do a true 4 wheel alignment. However this can throw off some front end techs since many use the rear wheels to align the fronts! If the tech doesn't know how to do it your car will look like an old beat up, lifted truck, driving sideways down the road!

so what do you guys recommend?

are normal, non-adjustable lcas good enough? This car won't be anything serious. Just minor/basic bolt-0ns, but I want to have traction and make this car handle tight.

For what you are wanting, you would be just fine with a pair of non adj. lca's with poly bushings.

If your not doing any serious drag racing, just the occasional T&T night then yea non-adj. LCA's are fine. Definetaly get a set of relocation brackets if you haven't already. The stock postiton of the LCA will create a shit ton of axle hop and destroy your rear. I reccomend still getting an adj. TA just to give you some adjustment in pinion angle (mis aligned drivelines break parts!). The TA will also help with wheel hop as it doesn't flex like the stock one. UMI, BMR, Sphoon, and many other companies big and small make all the parts you'll need. Pick a brand!

sweet. Thanks for all the help guys.

x2 on the relocation brackets.

X3 no point in having stronger LCA's without the relocation
brackets to help out.

Boxed lower control arms are my favorite. Edelbrock makes a really cool set with one poly end. But Im a straight line guy that likes to turn. I have BMR boxed control arms that im happy with. I dont get any wheel hop either
