Just beat your first rival, Its Vaughn Gittin Jr. its In the Drift option on the 3rd tab. All the way at the bottom an event called the final Slide will ask you to get 20 drift podium finishes before unlocking. There are 4 tracks you will have to do. The last one is annoying. You need to use a fast car like an exotic with works conversion becuase you need speed! On the last turn just drift as long as possible even if it means hitting a walls. that turn will give you alot of points. Try to get 1st on the first 3 tracks and you can afford 3rd place on the last one.
