My only suggestion is be careful with the +2 Speed Setting. It does work better on certain tracks, Crazy Crater being one of them, in my opinion. But keep in mind your Acceleration is at its worst, so if you hit something too much, or get hit by weapons, it takes longer to get back up to Top Speed than the other Settings. Taking these factors into account will help you adjust the Settings for your style or skill of racing. I have seen very few make a success of their racing in XP races with the +2 Speed, but One Piece Anime does pretty good.
Yea, Onepiece took me as a friend & told me a little about settings. Told me to set speed to +1 & drift to neutral or 1.
Its a big learning curve but it is still fun.
The first few tracks were hard when I started but now they are fairly easy so I must be learning something I guess? He he!
