I just put my 360M through a trackday yesterday. I drove the first few laps with regular setting and was very disappointed with the result. Then I tried sport mode which is supposed to give a different fuel mix (if I didn't understand it wrong), faster gear change through the F1, and stiffer suspension setting. The car transformed into another car completely different. The handling around the corner was big time different than from when I used the regular setting. F1 transmission with sport mode worked like a charm. The stiffer suspension allowed to car to be thrown into each corner with more confident. All in all, from now on I will drive it with sport mode.
