Securing Player Stat/Height System

So I’m making a game that invovles character customization, this is basiclly just hair, skintone, height, weight aswell as speed, power and other stats like that. I know I can just store the hair and other accesories in server storage but what I’m concerned about is height, weight and stats. Right now I have them stored in the starter character, I know these can be edited with exploits and then it would just take the fun out of the game for legit players.

I was thinking about making logic checks which would help with extreme hackers that make them selves huge or move really fast or just put their speed/power at 99. However this wouldn’t help against all hackers and this is where my issue lies.
