how do you move the mesh? also what program do you use to do it? will 3ds max work?First off you shouldn't trust the CM showroom to show you where colliders are. But if it works that way ingame too then you have to import the collider kn5, move the mesh (not any other object, has to be the mesh) and re-export it.
As you have no experience u should try it with 3dsimed, open the collider by draging the kn file on it, then on top click "primitiv" and "add", choose the car.kn5.how do you move the mesh? also what program do you use to do it? will 3ds max work?
