Just to chime in a little with my experience, I've had a bit of a clunk for most of the time I've had my Eibach sway bars installed.
Much more annoyingly however is that my Whiteline sway bar end links have now broken twice. The shop I've been going to for years initially told me after I had my car lowered that adjustable end links would help with the caster angle. I first had them installed sometime Q3 2022, then bought replacements in July of 2023 which we used Loctite on, and they're now broken again, just over a year later. The first set I think might've been done in from bottoming out a few times when getting used to the new height of my car, which is user-inflicted, but after familiarizing myself with the ride, I'm not sure why they've gone in the same amount of time. I don't really want this to be a yearly expense, when they should be lasting way more than 8,000 miles.
I do drive spirited sometimes, but it's never been tracked or anything, and I take speedbumps usually at 2-4 MPH and am very careful to avoid potholes etc.
I am currently undecided what I'm going to do, and am open to suggestions, although I'm pretty adamant in keeping the lowered suspension. The inconvenience is worth how much I love the look of it, haha
