Yes fit a standard Valeo clutch. You do not want to be going out there with the idea of driving as hard as you can or as you put it 'seeing what the cars capable of' - there is NO run off and you're 700 miles from home so don t get carried away, just enjoy the drive around it and don't go mental - I have had some close calls out there so take it from experience.
Plus if you want to try to go fast, buy a track day, don't do a tourist day - nothing worse than setting yourself up for that 80mph corner and getting half way round to find a bus pootling along at 35mph
Besides, the standard clutch will be fine, your not going to buy, and fit a clutch especially just for the Ring, and on top of that 200+bhp Clios last on the standard clutch, unless you leave your foot resting on the clutch pedal all the time and burn clutches out quickly, the standard one will be fine - it's bar far not the weakest link anyway
