Replication for IK Constraints with two characters. Help needed!

Hello guys!
I am making a custom vehicle system that uses a fake character on the client(so i have more freedom) and a real one on the server that is just welded to the vehicle. (and invisible for the client)

Anyway, i am planning on making an IK system (Inverse Kinematics) for the FAKE character, but i still need it to replicate to the server (real player / character). Now i could just move the target part on the server but that would mean firing a lot of remote events(probably unreliable remote events, but still). The game will have a lot of IK movements so firing this many events is just not efficient.

I was wondering if there are other ways to replicate joint movement from IK constraints (especially when they are not directly recorded in the m6d’s c0 or c1) from one character(fake one on the client) to another one(the actualy player on the server)

Thanks for reading any help is appreciated!

Why do you need that?
Just keep it on a client and let other players simulate it.

can you elaborate please
char limiit

Make clients do IK for it
Why do you need server to do that?
Think out of “server validation” boundaries.
