AMS2 is now updated to V1.6.4.3; this is a complementary update to the latest release with some further improvements & fixes.

As of this update, the Super Trophy Trucks class and its dedicated track layouts are available only to users who own the DLC or one of the packages that include it.

Beyond improvements to the new STT content, the wet & all weather tire treads have received further revisions; GTP tire compound wear rates have been revised and so have their thermodynamic properties, with compounds now having both generally narrower optimal temperature windows, demanding more energy to ramp up temperatures and offering worse performance while outside of this optimal ranges.GT4 & G55 Supercup thermodynamics were adjusted in the opposite direction, building up temperatures slightly faster and with slightly better performance during the progression.

AI cold tire calibration for these classes have been adjusted to suit these latest updates, with further cold tire calibration improments also for other prototype & GT classes. Other AI improvements include a redo of AI lines at Daytona and further adjustments to AI lateral movement rates in particular for GT cars where they could still move very violently causing frequent losing of control.

Stock Cars & Super V8 oval variant which were still to receive their V1.6 physics revisions have now been brought up to standard.
