There are 3 ways to complete this Achievement:
> Win a Rally Championship at Masters Difficulty
> Win a Rallycross Championship at Masters Difficulty
> Win a Hillclimb Championship at Masters Difficulty
You get promoted to Masters Difficulty by finishing a Championship in the Top 3. There are 5 Divisions in total with Masters being the final one.
When it comes to this Achievement, I would advise against attempting to complete it in the Rally category for the following reasons:
> The Masters Championship (Rally) consists of 6 events with 12 stages each.
> To beat the faster AI opponents you will need to set stage times that put you in or near the Top 50 on global leaderboards.
HomelyBumRocket's solution is pretty good if you choose to complete this by entering the Hillclimb category.
I chose to go with the Rallycross category for the following reasons:
> The AI drivers aren't as quick as they can be in Rally or Hillclimb events.
> As you can see
your opponents on the track with you, you don't have to rely on stage times in order to beat them. Instead, you overtake them on-track.I used the following setup for all events
, it will work on any of the cars in the Supercar category.
The event format for Rallycross is the same regardless of difficulty or event location:
> There are 4 Heats, with 4 laps each. You gain points depending on where you finish.
> Once the 4 Heats are completed, the 12 drivers with the highest point totals qualify for the Semi-Finals.
> The Semi-Finals are 6 lap races with 6 cars. Finish in the Top 3 to qualify for the Final.
> The final is a 6 lap race, win it to win the event.
There are 5 events in the Masters Championship, if you win 4 you're guaranteed to win the Championship.
