Question about wheel hub rings on track. I've read and was told mixed things from seemingly credible sources about whether or not to use them. On track, I'm running 17x9 Enkei RPF1 wheels w/ RE71R tires.

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?
There was a discussion a few pages back about hub rings when I asked, the long and short of it is:

If you torque your wheels properly every time, you don't need a ring, the bore doesn't take a significant portion of the load and is used primarily as an alignment feature. The lugs and studs do all the work.

I've got a set of plastic rings that came with my RPF1's, I usually use them for autocross because they're free and relatively low hassle. Except they get stuck and I have to pry them off with a screwdriver, need to get to the hubs with some scotchbrite and clear up the gunk buildup...

You can search this thread for 'hubcentric' and come up with most of the posts on the topic, but I already did it so here's the links:
