I agree to most of the comments here as well.
Don't try to mimic WR drivers. You might catch a trick or two but god forbit you race like that online as you wont last 3 laps.
Problem with the WR's is the fact that the majority of combos can not be driven that way in a race. They use strange lines, corner in an odd manner and the sets feel like on ice. They might be fast but it's also very unrealistic.
All you have to do is feel comfortable with the car and track...not be fast.
If you know to do X if the car does Y, you're more then ready to race on CTRA or any other server out there.
Yes, you will start in the back then move towards the center and so on. You'd be suprised how fast you can climb in position if you know how to react rather then just hotlap for that perfect line (32 on SO Town Rev....the line no longer exists except for the leader and the back marker).
Just get out and race and make sure you have fun. That's what this is all about
