This is what the (very rough) mock up chassis looks like at the moment. Rover engine, Audi AAZ 016 trans. I designed and made the exhausts, adaptor/mounting plate and flywheel, amongst other bits. The riveted on 1.6 mm ally side boxes more than doubled the chassis torsional rigidity.
I tested and was very pleased to record the following:
Torsional rigidity without side boxes = 2700 ftlb/Deg
Torsional rigidity with side boxes = 5700 ftlb/Deg
The chassis mass is 96 kg.
