There is an error in the manual regarding the steering post installation on the TC version. I have a regular XV-01 for comparison.
In step 11, the steering posts (BC14) need to be installed in the rear-most holes or else the steering linkage (adjusters, and turnbuckles) will rub on the rear portion of the front arm mounts.
In step 13, install the two BA3 screws to correspond with the rearward posts, as well.
I guess that's why they are there, because no kit specifies to use them in the official manual (including the truck version), but the Tamiya Japan site shows those being used in their pictures for the TC version (an overhead view is absent on the USA site.)
The front droop needs to be set to a minimum of about 4mm of downstop too, or some rubbing will still be present. It looks like one could file the top of the suspension mounts to improve that range. In the stock mounting position there is a ridiculous amount of binding without jacking up the suspension with the droop screws.
The servo link turnbuckle will also need to be shortened by about 5mm.
Hope this helps the other dozen or so people that bought one.
