Yes i've seen it in person. But I also know of two guys who have no issues. Unfortunately, I know of more contact issue complaints than of no issue complaints.
Another thing that I've had issues with, is the dakar springs have not been very good to me (installing on customer's Tacomas) with staying quite. Just lots of squeaking that despite me using all my little trucks to quiet down. As a very big ARB fan boy, I really don't recommend 2/3 gen Tacoma OME leaf springs anymore, and guide people to at least go with Icon leafs. Don't run Icon shocks due to too many seal issues these days, but their leafs (manufactured by someone else) have been very good to my customers over the last couple years.
