I ordered mine from Benny @ Levittownsupercenter before the price increased.
It came to my house this morning and I couldn't wait to get home from work to install it.
Installation is super easy just tedious
I was suppose to go and missed it because I fell while fixing one of my surveillance cameras.
I meet up with the crew almost every Sunday for cars and coffee in Paramus
Steeda might have missed this on their install instruction but it has been covered in various other suspension installs.
It's covered under this instruction manual. Don't know which one you used

I got Swift springs and love them. I installed them with the FR track package and the car is definitely giving me more confidence taking turns. I'm in the northeast so we finally warming up but I still haven't put it through its paces since my driving consist mostly of back and forth to work...
