Hey y`all,

I`m starting to race with sim racing system,
I would like to know what is the best place(races) for rookies to start a career.

What do you guys suggest?

I'm on Assetto Corsa.

Thank You

Obviously there are some Racing Series that are more suited to "Rookies" then others. But i'd say you should test out the different options. 
Can you handle the car safely? Thats enough. You can take part in races. But take it easy. Don't bring yourself or other drivers in danger on the track. If you can't handle a fight, stay away from it. And slowly develop a feeling how to compete in a race. And don't worry too much about your laptime. If you are slower then the rest of the pack, you should still take part of the experience you can gain. Just make sure you aren't a mobile blocking wall. 
And practice, practice, practice. Go into quick drive and learn the track and car combo. I see so many people join a race and they can't even handle the car on an outlap. 
Try the Skip Barber Series or the Lotus Evora. They are challenging but still manageable.
