No, in general an impact shield is only valid for the child seats with the appropriate homologation. In our case, the impact shield of Monza Nova IS is only valid for Monza Nova IS when used as a Group 1 car seat. The Monza Nova 2 SF and Monza Nova Evo SF have a different homologation and are only assigned to Group 2/3, where the child is directly strapped in with the vehicle's own 3-point belt system.
