Adjusting LCAs and PHB
I've tried a search. Maybe I'm not putting the right keywords in.
I just lowered my car with Strano Springs. I have UMI relocation brackets, ADJ PHB & LCAs.
It was brought to my attention that my rear tire is too far back. How do I fix this. Any links or insight would be appreciated.

First make sure you have the LCAs in the relocation mount holes that you plan to keep them in. Then at ride height measure how far off center the wheels are, divide that number by 2, your answer will tell you how much you need to shorten the length of the LCAs. Back the car up on ramps(leave the car in gear, and set the parking brake) and block the front tires. If there's enough inward adjustability on one end of the control arm, then just drop one end (the axle end will be the easiest) adjust it, remount it, then do the other side.

It depends what model you get... the single adjustable's must be removed to adjust. The double adjustable's allow you to loosen two jam nuts and turn the control arm on the car to lengthen or shorten the arm. Our on-car adjustables are the same way which feature poly bushings on both ends.

Thats the best way to do it. Just make sure that you get both sides the same length.

The adjustable LCA are to center the rearend forward/rear in the wheel well. If you're lowered you need LCA relocation brackets to correct the suspension geometry to what it should be (and I have a set of used UMIs for sale coincidentally)

Like mentioned you will not need adj. lower control arms if you lower the vehicle. We do however recommend a adjustable panhard bar. When you lower the vehicle the rear end will shift slightly and the panhard bar is used to re-center it.
Hope that helps!

Now if you have a aftermarket rear end like a Moser you will want to the adjustable control arms, but factory and Strange are ok.
Hope that helps!

You will be just fine with out adjustable lower control arms. I do highly recommend a adjustable panhard bar... being lowered and 315's in the rear will most likely lead to some tire rubbing.
Now if you have a aftermarket rear end like a Moser you will want to the adjustable control arms, but factory and Strange are ok.

how do you decide what holes to use on the relocation brackets?
