Any update on the lifetime of these and how they've been treating you? I've managed to get 6k out of the stockers (!) but they're not happy now so it's time to make that choice...
Want something for occasional track use, and lots of street. Had PR2s on a Sprint ST and they lasted forever -- that's the default choice for the MTS but it'd be nice to see if there's something a bit better for the trackdays.
