Cage tied in to the a-pillars. Risk of cracked windshield?

Thanks for the useful information.

Unfortunately it seems the cage I wanted has a flaw in that it is too low on the passenger side for me to sit in the passenger seat and let others have a go. I'm looking at options. This was a nice ChromeMoly cage which is very light.

Does anyone know the average weight of a good multi-point cage for a Boxtster?

Approximately 1.6 lbs/ft for 4130 chromoly tubing with 1.75" outside diameter/0.95 wall thickness. Photos are in the Spec Boxster Build link above.

A rough estimate of my cage is >50 ft (which was designed for safety, safety, and safety as the top three priorities) which would be a min weight of 80lbs.

I am sure that a cage can be built lighter (smaller diameter tubes, thinner wall thickness, and a simpler design using less material) ... but do you really want to skimp on the cage?
