Algirdas' video to convince me that torsional rigidity is improved.
Thanks for the link to that other thread Geoff, pissed myself laughing at such a load of bullshit - 'conventional wisdom' -ha ha, & that picture of the TR8 bar already bent to go round the carb really takes the biscuit...
Seems that you and me are in the same camp ... some time I'll rig up a dial gauge between the rear damper mounts and jack it up at the front and if it changes 10 thou I'll be surprised.
It's only the damper top mount, the inboard suspension pickups that create torsional loads are much further towards the centre. It will be the longitudinal box between front & rear that twists, not 'the humping big U section'.
Lotus quoted torsional rigidity of 6,600 ft.lb per degree so there won't be much twist anyway.
The Elan (T45) & +2 (T50) had tall suspension towers that racers used to brace with a good bit of rollcage design but wider wheels and sticky tyres created a lot more load than road cars anyway.
Helped to take some strain off the welds too... I can see the point of that but completely unnecessary on the M100.
