It says redeem rewards, that’s ok. But i don’t quite understand what i need to do to get points. Because it says 1345 points to next tier, but how do i earn theese points? Rcing on Forza, getting badges; titles? I really don’t understand it, so i hope some of you maybe know. And one more thing. I don’t have Forza 5 yet, but will i recieve the money rewards when i create an Forza 5 account in the same name as Forza 4? That would be great. OK That’s all, have a nice day 
This thread should help - at the end of the day it is all about playing the games.
Your gamertag will be the same on the XB1 so you can get the FM5 rewards as well when you get the game (the past rewards won’t come through as they expire after 30 days but any future rewards will be fine).
Yeah.
All you have to do is do the tasks given like getting the achievements in the game, buying DLC, doing a certain millage in the game, days playing, having stats etc…
Oh, and don’t expect for things to update immediatly; they can take about 48 hours to update.
And your redeemed Rewards, they don’t come now; unless you are not in the "Rush Hour”.
If you have another question, ask it.
Funky Dunk gave a good thread for this.
