I ran into a couple things that were limiting my RG7620's (Lo-
Pro Edge 7) pull-up range before it would hit the padded routed area.
When I got it, the action was a little high on the treble strings even with that post all the way down, so I shimmed the neck to get the desired action with posts even and knife edges a bit more than 50% above the face of the guitar. That would be slightly lower than where this trem is:

After that, I noticed the trem bar socket was hitting the body before anything else when pulling up. Once I removed wood from that spot, I realized the base was hitting a slight ridge of finish on the edge opposite the padded area, just beneath the knife edge in this picture:

I scraped the excess finish off, and that's what it took for the trem to finally max out from the fine tuner springs hitting the padding. Depending how the finish built up and how high the posts are, you might not encounter the second problem. I'd guess that the bar socket contact is more common.
