Instead, a severe speed penalty is implemented into the system, forcing the player to use the brakes. * A more extensive tuning system is available to the key users. Instead of simply modding the external parts, the performance hardwares are available as well this time. These can be performed in the online virtual garage. * A player can also activate the "Garage Extension" functions. This includes the benefit of having a team, customizing decals, vinyls and setting names and such.
