So you're now only reccomending those bars that connect to the bulkhead ?
Have you thought of servicing and how long it takes to remove a bar up out of the way of the cylinder head ? I speak for the majority of members whose cars spend 98% of their time on the road.
And my point was that since I've never seen a single bar fail, to do so will no doubt involve a very serious accident in which case, I'd rather have a rear half cage or perhaps more accurately described by Franky as a 'roll-hoop' which, as stated, also doubles up to seriously rigidify the chassis.
In this instance, neither front nor rear bar failed despite a twisted chassis but the roll-hoop saved the driver and passenger.
Besides, my bar (s) come with a cute, smelly-leather exclusive and original key-ring and the parts are life-time gauranteed. Lastly, any problems and I'm only a phone-call, email or PM away - all problems solved within a week.
Yer pays yer money and takes yer choice - it's a free country and becomming even freer later this year but maybe not cheaper
