Hi everybody, I would like so much help to operate some things here, would like too, to have fast cars in forza 4, to play on line and to fast laps in the liderboards, please someone HELP ME, S.O.S!!!
You’re going to need some help mentally also 
The things you’re looking for sounds like JTAG/RGH mods. Horizon doesn’t allow you to do those kind of things. Unless you unlock the fastest cars in the game with your credits.
Cant understand what you are asking for…
