Mario Kart Inspired Kart Physics

Ok, so the problem i have when debuging :
i see there is to much force aplied to the front wheels, so when i drive fast,
more & more force is pushing forward , then my car flips forward.
How can i set it to have more force on the rear wheels instead?
Normaly speaking the force should be on the rear wheels/suspension when accelerating and when you brake on the front wheels …
But instead when i accelerate, my car’s nose is starting to dive in the ground slowly until it flips.
Please help me out on this or idk make some lil tuto to help us understand a bit how it works …
Anyway, Thx.
