A car like the S2000 can benefit from higher octane and this is why:

The S2000 has knock sensors on it.

I was at this gas station yesterday in San Marino and noticed they have 100 octane racing fuel which is $5.50/gal. So i tried. I put in half tank of 100 octane fuel and 1/4 tank of 91.

The engine feels a lot smoother and makes less noise and vibration. I get better mileage as well. Other than those I don't really feel any big difference performance wise. It's worth a try if you get extra cash.
