From what I'm gathering for the BRZ on the forums - the wheels are centered by the lugs since they're conical, and after proper star-pattern torquing, there is no load on the studs/lugs. My alignment/race shop and a customer of theirs this weekend claimed metal (aluminum?) hub rings are very much recommended because they've seen broken studs when not used. I tend to trust them because they have several years of track experience and STI/BRZ specific setups but I'm a sitting duck on this one.
What gives?
FYI - I also run the RCE T2 400/400 with their out of the box recommended settings for damper clicks and I wouldn't say it understeers at all on track. It could very well likely be your alignment setup; what are your alignment specs?

I'm running -3/-2.1 f/r camber and zero toe all around. I don't think the understeer is pronounced but I felt it was there. I've since raised the rear a centimetre for clearance reasons plus removed extra weight from the rear (all the tools and the OEM Scion rubber mat on top of the spare tire) and it seems to have made the car pretty neutral.
