I really struggled with some of these events....London was a PITA! I used a Honda Civic (EK) '98 with Praiano's tune for a different model. For London, I came second or third numerous times...finally just cycled the AI line-up until I got the Civic 95 at the front and then won by 3 or 4 seconds. For Tokyo Bay, I again struggled with the Civic (closest to leader was 4.9 seconds, can't remember the line up). After seeing the advice in this thread, I got my Lotus Elise '96, used Praiano's tune for the Lotus 72 '01 (or whatever the model is), left the transmission as stock, and put 100KG ballast to -50 and adjusted the power to get 400....overtook the leader on the second to last corner at the first attempt. That car is fun although it does get a bit loose throttling out of low speed corners
