This tank has a great feature. Almost all of the guns, engines, radios, etc can be used on the tier 7 and tier 8 french heavy tanks, as of WOT v8.9.
This means you can safely research those modules right now and start taking advantage of them. Some of them are even required by future tanks.
You should double check to make sure in case the tech tree changes after v8.9, or in case the specific equipment you want is not useful later. Most of them are.
