A number of gameplay enhancements have also been added, including changes to the penalty system, tweaks to difficulty levels and reward balancing. Controller responsiveness, sound volume and Drift Trial races have also been improved. Sadly there's no sign of trophies. Before you run off to download the update, be aware that "rankings, arcade time trial times, drift trial records, as well as vehicle-specific quick tune settings and custom key layouts will all be reset with the new update. Replay data created before the second update will no longer be viewable after this update."
