For the MY2025, there were quite a bit of revisions to the suspension as well as cooling. I have created this thread to document all parts that are compatible with MY2023 and MY2024 vehicles, pending actual confirmation. If any information is inaccurate, please let me know and I will address.

The ATF cooler will not be relevant to MY2023 and MY2024. The sub-radiator seems to provide auxiliary engine cooling, but it does not actively cool the transfer case. Quite honestly, it's better to get an aftermarket radiator as any cooler additions would require the MY2025 front fascia. If you are so inclined to retrofit the sub-radiator, see @st165's post below:
Sub-Radiator Part Numbers
The most interesting change is the transfer case cooling duct. Per Chief Engineer Naoyuki Sakamoto, this change will not solve the AWD overheat issues, but it should help.
Engine Service Cover with Duct: 51405-12070
Main Under Cover with Engine Service Cover: 51410-12200

These changes are all made to help reduce squat and dive; therefore, reducing understeer characteristics mid-corner and on the exit of corners. The rear sway bar was likely changed to accommodate the new springs. The most important change is the rear trailing arm mount as it is an actual suspension geometry change:
Front Shock Absorber (LH): 48520-80832
Front Shock Absorber (RH): 48510-80C88
Rear Shock Absorber (LH/RH): 48530-80B99
Rear Trailing Arm Mount (LH): 48727-06060
Rear Trailing Arm Mount (RH): 48717-06030
Rear Sway Bar: 48812-12580
Sway Bar Bushings (x2): 48818-12440
Rear Coil Spring (LH/RH): 48231-12N20

Finally, some more bolt changes to add rigidity to the suspension and steering system:
Lower Ball Joint Bolts (x4): 90105-12429
Steering Column Bolt (x1): 90119-10A34
Rear Shock Absorber Upper Mount Bolt (x4) 90109-10194
