A lot of people are annoyed about the lack of full tuning in Forza Horizon. Items such as two-way differentials and fully adjustable spoilers are available to use in-game, but not being able to adjust settings and fine tune said items negates the point of them even being in the game. With the ability to fully tune a vehicle, many more people will buy the game. Not only that, but the people who have already purchased the game will be ecstatic. Full tuning will give the game endless longevity for car and tuning enthusiasts, and would make FH the only true open-world driving simulator. People have paid a lot of money for the game, so it is only fair to give your core fanbase what they want. I am signing this petition to force Turn 10's hand into putting full tuning into Forza Horizon.
