OK, well, I survived.
It was a good day out (a day out as the track was 2 hours from home). On reflection, I think I'm a little disappointed. Not in the car (it was a 2.0l RenaultSport with around 220bhp and 0-100 in 4 secs) - essentially a tuned Clio 182 engine bolted to carbon chassis that weighed about 400kg in total. It was more of a 'taster' rather than experience.
The 'track' wasn't really a track, it was a coned off section of the runway. Basically you got to nail it up the (fairly long) straight, along one side of the runway until a chicane which was marked using (very) small cones, exit the chicane to make a wide U-turn, hammer it down the other side of the runway (3rd, 4th 5th gear) then brake to do another wide U-turn and then head back up to do it all over again.
Yes it was good fun, but as it wasn't a proper track, you didn't really get chance to experience the car's potential, especially regarding corner speed etc. The car was stupidly fast accelerating in a straight line, but once you knew you were approaching a corner, you spent the time looking for cones, rather than 'following the road' (looking for curbs and the apex etc) if that makes sense?
Like a lot of these experiences, by the time you start to gel with the car, it's time to give it back. Oh for just one more lap.
I'm glad I did it, and driving the car was definitely an experience, but I really wish it had been on a proper track, I think I'd have got a lot more out of it.
Oh, one more thing - My Zed tipped over the 100,000 mile mark on the way home
