Chassis flex

As you can see this is Barry leading Peter Fitzgerald onto the straight at Calder. Rob Luck's engineer has picked up the amount of chassis flex evident. (See the headlight and driver's side bonnet). I can verify that the rear corners of the bonnet were not raised when the car was not cornering hard. Rob suggests that this would be arguably one of the most rigid Bolwell chassis of the time. Maybe, maybe not. That car had done a lot of work in the hands of Peter Warren before Barry got hold of it.
Like a good many of the Nagari chassis of old, this chassis is seeing lots of work to make it stronger and let's face it the engineers are justified in calling for more torsional rigidity than was acceptable 40 years ago, and I'm not just talking about Bolwells here.

Interestingly, and not as much as the Nagari but it seems to me if you look at the same corner of the Porches bonnet there is also evidence of body flex.

They're all under lots of stress in these conditions.
