There are a lot of mods you can play with, also new cars, new tracks....etc You can modifiy whatever you want (csm mod or manual changes into your gp4 folders with tools).
To begin, look at the GP4 faq in this forum for guides. I'm sure you 'll find many answers.Look at the topics too for work done from modders and members.
Now you have installed a clear GP4, I suggest you to look on sites dedicated to GP4 close from the community. Many F1 mods and evolutions from 1979 to 2008 are available:
