How to prevent Wheelie on WheelCollider

Okay, now i really need this help. I’ve been asked for 4 times but no one answers. This is the problem video

I’ve made 2 models with same script and same value, but the first one (red) likes to wheelie. Everytime you turn left it’ll flip right. The second one (white cube) works perfectly.

Really, really please help me. I’m frustrated dealing with this weird wheelcollider problem.

thanks for any answer

To keep a car from flipping over too easily you can lower its Rigidbody center of mass a bit from script, and apply “down pressure” force that depends on car velocity.

it actually the model’s scale
