Anyone running trailing/control arm braces sold by Hotchkis or Edelbrock?

[Buicksx3]

I did a search and many topics came up but most were related to frame braces, X-braces behind the seat, front end braces, etc. I'm just checking to see if anyone has found any benefit to running a pair of the Hotchkis or Edelbrock control/trailing arm braces that tie the forward mounting point of the LCAs to the UCA mounts. My car is basically a weekend car and set up for the strip with cargo springs, boxed factory UCAs, Hotchkiss LCAs, airbags, and poly bushings everywhere. Do these braces offer any ride or launch improvement, or just add weight?

Here's a link to a pic of the brace I'm talking about, marked by a red arrow:

Many thanks!

I dont have them but I did consider doing it. I may as one of the latter mods I do, looks like they can offer more rigidity if nothing else
