In the past I've always done more handling upgrades than power, and was always successful.
In the World Tour Mode, I've been trying to do the same thing, but it doesn't seem to be working as well. I'm usually able to catch up, or pass, in the turns, but then I get my doors blown off in the straightaways.
So, I'm just wondering what some of you usually do. Do you have upgrades that you go to right away?
I know the AI is supposed to be harder in World Tour Mode, but this is more challenging than I've ever seen. Certainly not complaining. I definitely like it. I just have to change up my philosophies a bit with this one. LOL
