What a way to use a high class planet...
I was playing this with "normal" level Arceans and was wondering how they managed to get their cultural influence so strong. Two fully loaded influence star bases just inside their border barely made a dent in it.
I'm now in the final stages of that game and just flipped an Arcean planet.

A 700% manufacturing bonus, and a 300% manufacturing bonus, then he loaded it up with 18 Influence centers. No wonder!
I would have probably loaded this planet up with food, banking, and entertainment, myself.
