Work [excellently] a year later, 14 track days so far...
I am using this sway bar adjuster on my 2016 Miata. My sway bar setup is Eibach front sway bar set to stiff, and rear OEM bar set to one notch stiffer than the factory location. The handling balance with my 9kg front and 5kg rear coilovers is perfect. The brackets are solid, no creaks and they are easy to install. You can use OEM sway bar end links and [manipulate] the angle of the adjuster to remove any sway bar preload like you would with adjustable sway bar end links.
