Question Lower Control Arms WTF?

I was just wandering how the a aftermarket Tubular Lower Control Arm helps my car get traction. if my car already has one how will this upgrade help? what does it do that the stock one doesn't?

Simply put, they dont flex.

The boxed or tubular anything is better than the stock stuff. Stock is a stamped piece, they flex, exactly what you dont want it to do. Boxed=good...tubular=better...and often times the aftermarket is a lighter piece, not usually worth writing home about unless you do the whole car and look at a cumulative total.

The stock LCAs are weaker in construction and have softer bushings than the aftermarket peices, thus making them more prone to flex & distort under heavy load.

Just as a side note, If you get a aftermarket piece with poly bushings on both ends, they can bind when the rear end twists, eg. making very hard turns. I would suggest a rod end/ poly bushing combo for a street car.

the re-location brackets will change the angle they attach to your axle and allow you hook better also

The stockers flex on purpose, not because they are weak.

The flex is there to allow for some articulation of the rear axle. Rod ends (heim joints) allow for much greater articulation (which is better for handling). Polly bushings limit this articulation and cause bind which can lead to unpredictable loading/unloading of the tires (which is bad for handling).

Sorry to hi jack here, but if you get aftermarket lca's do you have to get the relocation brackets?

No.
The relocation brackets are to restore the proper LCA angle after lowering the car.
