Also, I did see that there is a bearing that may start clunking.

And to my main point, I am looking for this to be helpful on trackday, I am not looking for this expense to make my car look better (fender to tire gap)

With that in mind, and because "I am already there replacing rear spring" I would love to hear some feedback and advice on this part
Red part goes on top. Spring sits between the gold cone shape piece and lower control arm. The gold piece on black rod is threaded and you can move it in/out of the red base piece to raise/lower it. That center black rod is 13mm hex head. It's so easy to use. Jack the car up and run a 13mm on long extension through the control arm and adjust as needed.
Thank you.

So I can already hight adjust with the JRZ spanner. Are there any other advantages?
