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?

Rings are not necessary, but it removes the stress from the stud from the first lug being tightened, if you're not evening tightening slowly, e.g. using an impact to put on the studs.
RCE T2 are designed to understeer. Making the T2 with stock spring rates neutral or oversteer can only be achieved by taking away grip from the front axle (which is slower; you're reducing grip).
