Can Anyone can suggest a good race car Ai asset.

I am developing a racing game like “Split Second”. The one thing I am struggling with is to make a good Ai opponent. Default Ai system is not enough to do the task. So can anyone suggest a good Ai Asset or any good tutorial for developing a great race car Ai.
