I see lots of Tier 9 players but never have I ever seen a player at Tier 10? Not because it really matters for me but if you want the 2017 Ford GT gifted when you start playing Forza Horizon 3 you’ll need to be at Tier 10.
Yes, tier 9 is currently the top tier, T10 will update it before FH3 launch!
No one is tier 10 yet.
Max points atm is ~ 15,986, since the Apex rewards for badges and events are still a little buggy …
On the other hand I’m pretty sure the tier 10 point limit will be lowered from the current full 16,000 points, until the release of FH3. Last year it was the same with FM6.
