I felt like I had it figured out by the end of the weekend. I think my qualifying results had me 5th and 7th, or something like that. I had a hard time in the first race, but was making mental notes on where I was loosing time to the AI, with the two biggest causes of timeloss being Becketts and Club.
I was having trouble sighting the entry at Becketts and would end up either braking too earlier or turning in too early. I used a small patch of concrete (maybe even an access road) on the left as my braking point and found that you can carry a lot of speed through the corner, especially if you use all the road on exit.
Club was the other (and probably most important), which was simply me driving too deep into the first part of the corner. I found that the Clio is quite happy to curb hop rather aggressively and that the best way around Club was to brake hard and turn in very early, using all of the available curb on the left hander, all while aiming at the apex of the first right hander, then flowing it through onto the home straight. This sequence is also critical for setting up passing moves at Village.
I managed a 6th in the first race, but by the second race I had identified all these areas and put them to good use. I pitted from 5th as soon as the pit window opened and was able to use clear track to jump myself up to 3rd by the end of the pitstop cycle. I attempted a pass for 2nd at Village on the last lap, but couldn't pull it off. At first I had thought I didn't like the new International layout, but by the end of this race, I was enjoying it.
