Yeah.Hey Chingy,how can you race against other kings?I finished some race days,and I got straight to Ryo.I never raced against Krieger and the rest of the guys...
You have to completely conquer race days and showdowns. When you select the first event in the Elite Kings, it will give you a target of what to beat/win to unlock it. I.e. break 5 track records etc.
I installed the game again,and I will try it tommorow.
