IME only a drawback if you want to change the setting or didn't set it to desired stiffness the first time. I ran Yellows one full turn from soft and it was way better than the wallowy stock shocks. Even softer than the Bilstein HDs I have now with sport or stock springs. Handles great without being too jarring on bumps or potholes.My earlier Koni Yellows had external adjustment for the front shocks...the Passat shocks needing to be removed sorta negates the adjustability, to me. I got them cheap and I'm happy with the ride, but that's definitely a drawback.
