Update on this problem. I called Stance about the issue and they mailed out 2 Thrust washers to install to the top of the spring to remedy the spring binding. It turned out that the collar that locked the springs in place was loose, so I tightened it. The initial test drive was good, but the noise came back. After 1 day it was gone, so I guess the springs needed to dial in again. Therefore I did not install the washers. This was back in November.
I've always had memory steer issues, so a few weeks ago I decided to loosen the springs a little to see if it would do anything. The only thing it did was bring back the annoying spring noise. Therefore, I decided to install the thrust washers i got from Stance in November of last year. The thrust washers improved my steering, because it seemed easier to move the steering wheel compared to before. The initial test drive was good, but 30 minutes later the spring noise was back.
Some of the preload settings i tried were
1. light with some play meaning you can move the spring up and down and turn it effortlessly. Stance says on their website to not preload the springs.
2. Very tight where you can barely move the spring by hand.
I jacked up the car and recorded a some videos showing how the spring is binding.
I put load on the springs by using my floor jack on the LCA.
NOTE: Although spring seems to stop binding from the top perch, the spring noise is coming from the bottom perch.

I'm going to call Stance on Monday and find out what they can do.
