Ever since I've been wondering how to improve the otherwise spectacular Boxster chassis. Those excellent pics don't show 2 major structures along either side of the floor. These are used when jacking the car up and/or for jack stands. Perhaps they could be fortified. Also I think adding an additional bar ( with triangulation) in the lower door openings perhaps 6-8" above the sill would be of the most benefit. Entering and exiting wouldn't suffer much- it's just the install--weld, bolt or bond?

A bolt-in cage might be the most cost-effective way to improve Boxster chassis stiffness. It also offers a lot more driver protection for motorsport. I favor a custom welded cage for safety but they are also a lot more $$$.
