I just aligned mine with the factory bar and made sure the threads were equal on either side of the nuts...no problems yet with mine.

No kidding. Everytime I see a pic of the new ones with the adjustment in the center it makes me cringe.

Why would anyone connect 2 LCAs together with all thread and call it "extreme" is either a crazy or marketing genious.

Did you mean two panhard rods?

No ... either half of that design is about the length of an LCA.

Connect them with all thread and voila ... instant APHB

connection points double ... one on each end and 2 side by side in the middle.

As far as ease of centering ... you should only have to do it once.

Would you even consider connecting 2 LCAs with a piece of all thread and using it in a loaded environment?

If you needed a shorter (or longer) pushrod in the motor, would you grind them down or lengthen them?

Same difference and probably less loading on the push rod ... around 250lbs of constant spring pressure vs 15000lbs (1/2 the car's weight at just under 1G) of loading, alternating between compression and stretch.

So which PHB would you recommend? I understand somewhat what you are saying, but do you suggest to use?

Get one from Trackbird, they're aluminum and use the same awesome rod ends that LG uses, the QA1 XM series

Not only do you have the reduction in cross-sectional area and the additional stress-risers associated with the adjusment, but you have it located at a very critical point - that's the thing that bothers me the most about this design. If you place the bar in compression (e.g. a righthand turn) the maximum bending moment in a simply supported slender column (assume its experiencing both axial loading and bending loads) will be at the center of the length. Exactly where the damn adjusting feature is placed with the BMR design.

The bar may well be "strong" enough to handle the loads placed on it, but IMO that just means that weight could have been saved with a more elegant design.

That is very interesting...

So what if you went with a design like Spohn where the adjustment in the bar is towards one end and not at the middle, but still having tubular ends with poly bushings? Is there a difference in this design? Just a thought...

I'm all for innovative ideas and trying new things.
But sometimes, simple is the best.

I've found what I like and it works very well for me. I'm tired of investing my hard earned money on an experiment.

I'm with Mitch, and I was thinking the same thing when I saw that picture. Please tell me that BMR POS is not under a $100,000 Berger car.
