KW HAS Rear Links

I suppose KW knows this and that's why they ship their HAS kits with 3 links.
To add insult to injury, after I finally got the spare link on, the car remained at about the same ride height (i guess I didn't shorten the link enough). Now, I do not have any more spare links. I didn't want to try disconnecting it again out of fear of snapping this one too. Can any one recommend a BETTER adjustable link? I just saw these on eBay https://www.ebay.com/itm/Mercedes-W2...UAAOSwdrhbyz7c that are metal and have these pins that lock the units into place. I wish they made ones that you could adjust without having to pop them out of those studs!
Also, if you have adjusted your ride height via links, do you have to do anything in terms of C, S and S+ modes while doing this job? Obviously, one would do all this work under the car while the car is NOT running and shutting off the car would mean it resets to C. What needs to be done with respects to this?
Thank you all in advance.
