Default Adjustable lower control arm ???

I need to get some adjustable lca's but am concerned about the clunking I was getting when I tried a set that had non-poly ends. Will the arms with the poly/rod ends be as quiet as stock, or will I have to go with the ones that have poly on both ends and adjust in the middle?

Hello
When going with a single adjustable rear control arm! The only time that you will get a clunk out of them is when the rod ends go bad! But keep in mind that when you go with a rod end on the chassis side it may highlight (bumps) but will hold up a lot better than a poly bushing. Below is a link to show you what all UMI Performance has to offer!

If you have any other questions feel free to ask and I will be more than glad to help.
Thanks
Brad

Thanks for the reply. I do plan on ordering a set today but I am concerned about how they will affect the driveability. I don't want to be annoyed driving my car because the streets around here aren't necessarily the best. I do have some non-adjustable lca's on the car now but the driveability didn't change from stock after installing them, probably because they have poly on both ends.

I went from poly/poly to poly/rod and there's little to no difference in sound or harshness

BMR uses there own size bushings and you would need to get them directly from BMR.

Hope that helps,

I noticed that UMI stated that their relocation brackets won't work with aftermarket rears. I have a 12 bolt and everything bolted up just fine. I wonder why it isn't supposed to work.

We have found that our brackets, both bolt on and weld on work fine on the Strange brand rear ends. Some aftermarket rear ends such as Moser make there control arm mounts wider than factory and also place there shock mounts more inward. When this done it does not allow our brackets to fit correctly.

Hope that helps,

Hello,

The design itself is very similar in how it operates and how it assembles. Some of the differences include the internal spherical ball. We use a one piece ball while our competitor uses steel sleeves to change the length and hole size. Also on our panhard bars we use a smaller "mini" Roto-Joint. We do this for articulation and correct movement. Using a larger body like our competitor does will restrict the panahrd bar from moving. The joint will max out in the mount by hitting before the panhard bar is able to makes it correct movement. We also use a inner locking design while our competitor uses set screws.

Another thing we are very proud of is our Roto-Joint is built 100% here at UMI's facility, all items installed in the Roto-Joint including the housing and with the exception of the lock washer are machined right here. I don't know if that is the case with the others.

Hope that information helps, if you have any additional questions please ask.

Thank you!
Ryan

Thanks for the explanation. I never got to see all the differences. Will keep this in mind when I go to another set over what I currently have(poly/poly) soon. Again-Thanks.
