Eibachs are talllll springs compared to what I've had in some of my crap. I had 3.5 coils cut on some stock springs and they never fell out for no reason, but as soon as I jack the rear up they'll fall right out. I do know that one guy at MW flexed his car out on a crazy inclined entrance and his spring fell out. It was hilarious.
This is exactly why I created this thread, and what I'm worried about lol
