Claim:
1. A brake disc arrangement for disc brakes, comprising: a friction ring; a mounting adapter configured to mount the brake disc arrangement on a wheel hub; at least one connecting element configured to connect the friction ring and the mounting adapter; and at least one contour having a friction ring-side and an adapter-side contour region, wherein the at least one contour is shaped along a longitudinal axis by recesses in the friction ring and the mounting adapter extending at least one of perpendicular and transverse to a rotational axis of the brake disc arrangement; wherein the connecting element is brought from a first state into a second state by applying a same inner pressure within the friction ring-side contour region and the adapter-side contour region of the connecting element, wherein the inner pressure is applied by at least one of hydro forming and hydro-mechanical deep drawing; wherein the connecting element in the first state is configured such that the connecting element may be arranged inside the contour; wherein at least sections of an outer diameter of the connecting element in the second state is enlarged relative to the first state in at least one of perpendicular and transverse to the longitudinal axis, such that the connecting element is connected to at least one of the friction ring-side and the adapter-side contour region by at least one of form fit and friction fit; and wherein the at least one of form fit and friction fit of the connecting element with the contour is adjusted due to at least one of a wall thickness that is not constant along the longitudinal axis, a diameter that is not constant along the longitudinal axis of the at least one of the friction ring-side and the adapter ring-side contour region, different inner geometries that are not constant along the longitudinal axis of the at least one of the friction ring-side and the adapter-side contour region, and different material properties of the connecting element.
