I like the idea. I think it's perfectly rational. I'm not sure 5% is
an accurate figure. As much as anyone who's spent the bucks on those
fancy autocross tires will hate to admit it, they probably only gain 2
to 3% over a good street tire. (based on my own experience, ymmv... but
2 seconds on a 60 second course is only 3.3%)
