Unless your car has a variable map and the correct Lambda sensors to tell it what fuel you are using, you should get no "noticeable" performance improvement by using higher octane fuel. If you use a sub-standard fuel, you will notice. You need to know what fuel your car is mapped for in that case. Most are for standard 95 ron.
A higher octane fuel will allow a cleaner, more efficient burn so the performance will be marginally better, whether that is noticeable is debateable.
A highly tuned or highly strung engine may require more RON to help keep the top of the engine cool and cut down on knock under high load. We map the competition engines on either 95 or 97 ron fuel then actually run them on 97, 99 or even 102 (if we can get it at the right price) as a sefety measure. If we get a bad batch of fuel (It does go off in the pumps if stored for a long time) we at least have a safety margin.

got to Tesco today and filled up the 350Z with 99RON - i'll see how the mpg does over the next weeks commute on the M62
i'd be interested to know how you get on....my other half uses BP Ultimate, which is 1Ron less than recommended.... (not that that'll make a blind bit of difference like, buy, you know.....)
