Sorry if this is too late...
I think they just meant to mount the shocks on the rear of the rear arms instead. If you have the high-traction arms (come with the DB-01R), there are already holes there. Otherwise, you need to drill new shock mount holes.
The camber link needs to be moved about too (I moved mine to the front of the tower).
I still can't tell what this does on the track, but it made shock and spring access a lot easier (while the HT arms lasted, I didn't bother with the drilling mod on regular arms).
