That's what I would recommend, if you can afford it. The FEA analysis I've done for different cage types clearly shows trends on how they affect chassis stiffness. In a frontal torsional load case (like I showed above), even going from a regular 6-point bar to a 6-point with full upper structure with A-pillar bars results in less than half as much chassis twist/displacement. Also get a good, experienced cage builder to do it who will tie the cage into the unibody at as many places as possible or allowed.
