Things I need to do before forza 6

Could anyone send me a link of thing I would need to have done b4 forza 6

Top level or close to top teir

I herd for every 300 cars in each game I get 5mil credits in 6

Anything else I would need certain cars? Or anything like that

Thanks

Quickest thing to do is load up the forza hub and it will show you everything you have and have not completed to max your tier level

Or click Rewards → Overview in the header of this website. that will tell you where you are Tier wise. Forza hub will tell you what you are slated to get in terms of cars and credits.
