I think the ring comes with the shifter, not the cable, but I could be wrong on that.
Also, for my 02 I got the STI shift boot and surround. It HAS to be from an 04 STI though, later model STIs won't work unless you do a center console swap. You can make your stock stuff work but it won't look or work as well. There is that big lump below the reverse lockout on your shifter has to fit in the boot some how and it doesn't really fit the bugeye boot. The 04 STI boot has a button on it so you can open it up to fit it over the lump and it fits muuuuch better.
