Wheel problem

Hi, I imported the "Car Tutorial" Asset into Unity, and that model was working fine, but I wanted to change it, so I got another model(Aston Martin DB9) from NFS Shift, changed the pivot points to the middle of the wheels, assigned everything, and now I get the problem that you can see in the image below

Both back wheels are almost in the same position, below the ground. Can you help me? Thx!

Update: While doing some stuff to find the problem, I decidded to put the car on a cube, and I found the collider is created in the wrong place, maybe because the collider creation position is from the asset prefab car, but I don't know if that thing is in the script. I also put the prefab car and the collider was in the same place as the wheel. you can see the rear right wheel colliders of both cars in the image below.

Do you have any idea how to change the collider position? Maybe it'll work.
