Everything was going well until I reached the Tier 6. I came to the point having most of podiums till T6 but suddenly everyone else got super fast and I stuck in the last 2 positions in every race. It's almost impossible to hit the average upgrades of parts due to the lack of resources. It's kinda sad that it became a grinding game unless you wanna spend some money. I'm just watching my fellas to finish the race 19th 20th positions to just achieve some resources for upgrades. Disappointing.
