Along with the usual long list for general fixes & improvements, the new update adds the new Brazilian Stock Car 2024 season & a completely overhauled F-Ultimate Gen2.

As indicated in the 2024 March Dev Update, both the F-Ultimate Gen2 and the Stock Car 2024 already feature the V1.6 tire physics developments with adjusted hysteresis (but only partially revised thermodynamics & wear) - generally speaking the updates tires should feel slightly "sharper" and less tolerant to sliding than previously.

Both classes feature their 2024 respective DRS and Push-to-Pass rule updates, with DRS being allowed after lap 1 for the F-Ultimate Gen2 while the Stock Cars feature a higher number of shorter P2P boosts with no activation delay.
Still on the content front, following popular demand the Betonschleife (aka "concrete circuit") has been added as an option for the Historic Nürburgring , part of the Nürburgring DLC pack.

AMS2 V1.5.6 also features a much improved water shader & 3D trees added near trackside for several circuits and visible dust clouds from cars running over dirtier parts of the track, all components of the visual updates in progress for the V1.6 milestone update a few months from now.
A note of appreciation and apologies to livery modders such as @KRRTDustin, @TomLehockySVK and others in the community who had done great work with the old F-Ultimate Gen2 model that has now been retired - although we couldn´t justify retaining the old model given the lack of actual differences in specifications and inferior quality relative to more recent releases, it wasn´t a decision made without consideration and heartache for the impact it would have on your livery packs. We hope you find the much improved 3D model to be worth the trouble and that it proves a lot more fun to work with moving forward!
