I have no idea man. I've never owned a single piece of UR stuff in my entire life. And looking at their stuff, I doubt I will own any in the foreseeable future, unless they acquire proper engineering technology.
I either leave the car stock standard as it is from the factory, or install proper Japanese/European engineered parts on it. I don't compromise when it comes to safety. And I don't like to guess whether the part works or not, and neither would I want to be a lab rat to test their products, and when the product is a failure in design they come up with a new v2 product. Just like the UR 1st version rear lower arm bar.
I find it pretty stupid to pay money and buy a product and test it for the manufacturer, and if it works, good lor, doesn't work, I put my safety, my family's safety, and other road users in danger, and thereafter they come up with a "new" version 2 design, after I, the consumer, find out the product doesn't work.
If you want to modify your car, do it right, or don't do it at all.
This is merely my opinion, having no experience with their product, but having observed their "designs" and feedback from other actual users (or lab rats) I will stay the hell away from UR.
An example from a Proton Inspira club
Is it worth risking YOUR life installing rubbish in your car? Up to you man. But if your brakes fail, caused by UR or any other rubbish product, please drive yourself to the nearest tree or ditch and kill yourself, don't harm other road users.
P/S Don't misunderstand, I am not being rude, I'm speaking in a matter of fact fashion.
