You know, your guess is good as mine even in Calderidge which I love this track with big rig but I do prefer bike. and yet I struggled to beat them!

My advice to you is, just trust to yourself and you will get there. If for ranking points, try to stay under top four every race, no matter what!
That`s how I got my plat.

Now I`m reaching 75% on Apocalypse atm.

Just add my psn
