How to unlock the Global Superstar achievement in DiRT 4 - Definitive Guide
RoRoRacing also added the following to help you guys out:
Good guide, just wanted to add to please pay attention to your championship standings. The max points you can get for each event is 25, so if you get to the final event (6 stages) and you're leading by more than 25 points over the next guy, then you can start the event and then immediately retire from the event. You will place 30th in that event, but you will still win the championship and pop the achievement. I had 100 points going into the final event and the next guy only had 66. You'll see in the first few events who is coming in second, if it switches to another driver like it did with me, then you shouldn't have any problem getting more than a 25 point lead. That saved me from having to race the last 6 stages.
When leaving the DiRT academy when you start the game, you will earn your first license which will allow you to play in your first Rally event. Completing these events will unlock other longer events. Make your way to the last event, which will be the Global Rally Series. Once a new set of events is unlocked, you don't have to beat the remaining events in the previous one if you don't want to. While progressing through your career to unlock the last event, you will also earn the International Rally R-3 and R-1 licenses which will give you their respective trophies.
The Global Rally Series has 5 events and every event consists of 6 stages. You don't have to win all the stages but you do need to get the best overall time at the end of each event to earn the trophy.
It's better to make a backup of your saves after the 3rd event.
