Forward vector not changing with rotation of object

Ok so i have a Sphere that i am adding a force to and then copying the location of the Car to the sphere.

Then i am taking the average of two line traces downwards to get the normal vector of the ground to adjust the rotation (Pitch).

For the Yaw i am rotating the Car with two inputs and then the sphere gets the force based on the direction.

As you pointed out, i think i am applying a rotation to the mesh.

How would i go about changing the actors rotation?
