I have a Thule 460 podium kit with the Thule Square Bars (50" load bars) that I just put on the top of my Subaru (2013 Impreza WRX). The podium feet fit fine, but the square crossbars can be slid side to side fairly easily. In fact, if you remove the rubber ends, you could simply slide them off the rack.
There doesn't appear to be any adjustment for this, either. It's almost like the square metal loop needs to be tightened, or the crossbars need to be a few mm thicker. All three bolts on each podium foot are tight, but I don't want to overtighten.
Anything I might be missing before I bring it back to the retailer?
FYI This is what it looks like:
