First let me wish You a good luck! You'll sure need it.

I would add just one thing. Make the competition a real story. There is nothing more boring than just simple telling results. For that no wall of text is needed but just one table. Make all You can out of all the dramas which naturally happen in every rally event. Don't concentrate only to the professional top crews but show also the adventures of outsiders for whom even the starting ramp is a kind of small victory. People generally love stories about poor heroes fighting against all odds because they can find many similarities with their own lifes and dreams. There are always really good drivers who combine daily work shifts with nights spent in a garage, finishing the car just few hours before scrutineering, facing various troubles afterwards but still making decent competitors. I'm sure You understand what I mean.
