About ’Custom Game’ create…

Hi!

At first… my English is very poor.

I wanna create my ’own rally’ with my 5 friends WITHOUT these The World’s Best Driver (what incl. the game), but I don’t know what part of Dirt 2.0 is it - or is this possible ar all?

Usually I play in ’Training’ Part and every time I’m last one in rally! 😂

So… some kind of ’Custom Rally/Game’ I think to need - anyone help me?
