Besides the look of the track which is spectacular, the driving dynamics are perfect and this is my favorite track in AC.
The high speed ring just plain has everything to challenge a driving set up. The first braking zone will challenge your ability to trail brake at high speeds into a long sweeping low speed turn. You then need to get on the power cleanly while still cornering on the exit. Pure excitement to keep it floored through the straight with bumps and kerbs. A braking zone over a kerb with the high speed left hander up the hill will drive you crazy to find a good suspension balance since exit speed is crucial here and it is so easy to miss either the entry or exit . The next right hander is pretty standard and can be a passing zone but you will lose a ton of time to the field if you use it for that. The next right hander is a high speed expanding radius sweeper that demands a good setup and good balance that will counter your suspension needs on the previous left hander already mentioned, and you can lose a couple tenths here with a bad set up. Next, is a very fast right hander off camber and downhill that will have you fooling around with dif settings and wings to keep the back end on the track. The switchback here demands a tight responsive car that doesn't move around too much. If you are fast up to here the next right left corner series is pretty easy with throttle control but very fun to manage. The exit into the finish line has a razor thin margin of error and if you bink either kerb it might ruin your race and not just the lap.
This track has incredible AI and they are frustratingly fast on some very difficult corners. The AI on the small track can crash but it's manageable and not broken. The racing on the small track is very fun as well, especially with a full field for constant action.
Don't miss out on this track!
