OK, let me think about this...
Did I REMOVE the Calmini drop bracket, when I installed the Anvil? I THINK so!
You're breaking CV joints because you installed the RRO spacers (which increases CV angle) without dropping the diff (which decreases CV angle).
BUT - if you drop the diff, without putting longer A-arms in (the rest of the Calmini 3" lift), your outer axles will be TOO LONG. So you gotta get longer A-arms, or custom axles to drop the diff, and get the benefits of lowering the diff.
