Default adjustable or non adjustable

What are the benefits to the adjustable and non adjustable. Panhard bars and lower control arms. I'm just a everyday driver, the only racing I do is some grauge matches at the drag strip

If you're just driving on the street, you don't need aftermarket LCA's. A panhard bar that is adjustable is useful if you're lowered, or have an off center rear axle, other wise you stay with the stock one.

I know on my car, the LCAs especially were not fun to get in place. I am very happy I got double adjustable so I could put them in, then position as needed.

It would have been a nightmare to install them, check to see if the tire was centered in the wheel well, then pull them back out, adjust and reinstall.

Would have to push and pull the axle to get it in place to put the LCA bolt in while the whole car is on jackstands, hoping it dosent fall on your head.

Well I just bought a cheap set of lowering springs. And I'm going to be running nitrous at the track. Hoping to break 7 seconds in the 8th mile. Are LCAs even needed?

There comes a time when power output and launch stress will twist up LCA's. The trick is to install UMI's before that time comes.

As for adjustable vs non-adjustable. It's always better to have it and not need it than need it and not have it. If I had a car which I knew was completely straight and a rear which I knew was perfect as far as brackets go, I'd run non-adjustables not problem. Also, for street driving I'd definitely run non-adjustables without hesitating.

As Valkyn mentioned above, it's sooooo nice to have that option to adjust if you ever need it.

For PHB's it's so nice to have double adjustable so you can dial that baby in. For stock street driven never lowered vehicles, I'd most certainly trust a solid bar, after all your car had one on it from the factory. Ours is just like that but better. If you're honest with your suspension goals, sometimes you can save a few bucks with no negatives.

For the relatively small difference in price, adjustables insure that you never have an issue. Different rear axles have their brackets welded and it's not within a few thousandths of an inch either, that's an example of where adjustable LCA's can be helpful. If you know your thrust angle isn't messed up now and you are staying with the same rear axle then non-adjustables would be fine.

Same with the PHB, If you ever lower the car, or want to just move the body a little you need adjustable one to do it... and the price difference in very, very small. I've got the entire UMI product line, as well as a few others I really never sell because UMI is the best value.

For a daily driver, you just set them and rarely change them. If you are an auto-crosser and aggressive canyon carver, get the adjustables.

Thanks for the UMI purchase!

Have you decided on adjustable or non-adjustable?

As for LCA's I run Global West's non andjustable. They have a spherical bearing on the rear end side and a rubber bushing on the frame side. They're great, I've really enjoyed them. I also have UMI's PHB and it is a very nice piece.

i twisted my stock lca's which is stamped steel. it twisted it enough the car would pull hard to the right. I got umi on car adjustable poly roto joint lca's. then i got my thrust angle set to 0. All of my suspension in the rear is adj. that is why i can launch hard.

Thrust angle is when the rear tires are completely parallel with each other (or toed in properly just a hair) but not on the centerline of the car. Basically it's like you lengthened one link an 1/8 inch and shortened the other and 1/8 inch.

If you have your differential brackets out of square, a pickup point on the chassis tweaked, etc, the thrust angle can be off. The adjustable LCA's allow you to skew the rear tires perfectly straight ahead.

Single adjustable features a single rod end which requires removal of the LCA or PHB main bolt to turn the actual rod end and make the length change.

Double adjustable use a R and L threaded portion which allows adjustment via turnbuckle and doesn't require removal of a fastener.

To know when your diff housing is centered, hang a nut from a string taped to each rear fender lip. Measure to the face of the sidewall and adjust until both measurements are equal.

And thanks for considering UMI!
