Aluminium AC Cobra Chassis

Mike it's not up to me to disclose FFR's torsional figures as there is
another company importing and distributing them, it wouldn't be right.

IMHO a huge torsional figure does not make a car any better than an average figure car to drive. I bet someone like Craig Lowndes could tell the difference
bewteen a 7000nm and a 11000 but the rest of us couldn't.

I don't reckon it makes that much difference either. A degree or so difference in twist it's going to mean anything on the road when you take into account the amount of movement in the suspension.

You might notice pick the difference in the body movement Depending on how it's mounted but I doubt it.

I think a flexier car with a well designed suspension setup is going to feel way better on the road than a rigid chassis with less than ideal suspension.

I agree 100%......I think sometimes torsion figures are used as phallic symbols.

IMHO a chassis's torsional number would make no difference in which brand of kit I bought.

I corner weighted 4 different brand kit cars on the weekend ,2 Cobra's, one coupe, one DRB GT40. I found that even though the torsional stiffness of each car was greatly different, all the cars responded very well to spring platform adjustments...meaning that all the chassis's where stiff enough that small changes in ride height moved weight around the vehicles. A sloppy chassis would take inches of adjustment where the DRB GT40 for example showed weight changes/transfer with 5mm of adjustment.

IMHO that means that chassis is torsionally stiff enough for the application of Fun sports car/ hobby race car.
It responds well to changes and really why would it need to be stiffer?
