Systems are provided for suspensions that deliver desirable wheel kinematics at prescribed conditions. A system includes a vehicle body structure with an engine cradle, and an associated wheel assembly. A suspension system links the wheel assembly with the engine cradle, and includes a link coupled with the engine cradle and coupled with the wheel assembly. A joint at the link includes a flange that has an opening, an edge, and at least one undercut defined in edge of the flange. The joint allows release of the wheel assembly from the engine cradle by designed tearing between the opening and the at least one undercut. The release is initiated only under loads above a select threshold at the joint, to provide select kinematics of the wheel assembly for specific operational cases.
