Yes and they are helpful. I can tell if one is installed in a back to back drive but the effect isn't super noticeable unless you're at an inch of drop or more. I've only tried the Whiteline kit which doesn't relocate the outer pivot a ton but it's easy and includes the tie-rod extenders for bumpsteer.
With the bigger drops on these cars you NEED roll center correction and/or some very firm spring rates especially up front (and that's pretty obvious whether you're looking at the KRC or FAPs or just the camber curve). A lot of people JUST try to pick spring rates on these cars by picking suspension frequencies and designing for a flat ride at 80 mph or whatever and IMO that's leaving a lot on the table and pretty shortsighted.
