Adjustable Vs. Non-Adjustable This winter im going to be getting a bunch of suspension parts and im trying to decide if im going to need adjustable LCA and PHR or non Adjust. I do plan on lowering the car so it seems that the adjustable ones are necessary. I just wanted to know how to properly adjust them so the rear is centered right and how the drivability is. I was looking into the UMI, BMR, and Hotchkins. What are the pro's and cons of each. At this point im pulled more to the UMI's single adjustable.
By the way my car is an 02 SS.
Thanx for any help

* Adjustable LCAs allow you to adjust the rear axle forward/aft/diagonally.
* Adjustable PHB allows you to adjust the rear axle left/right.
* With both you can adjust the rear axle in all horizontal directions (left/right/forward/aft/diagonally) to center it under the car.
* Ajustable PHB isnt necessary for stock right hide, but is necessary when the ride height is changed (ex: lowering the car).
That being said....
I have stock right height, but I do have adjustable Spohn rod/poly PHB and LCAs. My rear was a bit off with the stock parts and is all straight now with the adjustables (adjusted by the mechanic during an alignment...you have to ask for it and may need to convince them to do it).

Be careful. Asthetic adjustment doesn't necessarily mean the rear diff is true and square. with the running gear.
You can have the rear wheels centered in the wheel well and the wheel base be 1/4" longer on one side than the other. this will make the car "crab", causing all kinds of wear and handling issues.
I'm not saying it WILL, I'm saying it's POSSIBLE.

I had it aligned by the tech during a 4-wheel alignment.
It took some convincing to get him to do it. He insisted that there wasn't anything adjustable back there. I had to walk him over and show him.
