How to adjust ride height with sliders?

So I've been trying to make custom suspension for the 800 series, using the ScrapeWorks ETK-I as reference. What I've done is copied over the slider variables over to the 800 series suspension files, but it doesn't do anything ingame. It's probably going to be a stupid mistake, but what have I done wrong?

 

Here you go bud. The only things you forgot to add was the "$ride_height_F" and "$ride_height_R" in the beam precomp value. You can see what i did in the file.
Here are some #stancenation #needsmorelowphotos

 

Awesome. Thanks so much!
