Here's the thinking, Kenny.
It is pretty commonly accepted that the alloy/alloy combo is way too stiff in standard form, even for high grip surfaces. However, with the alloy top deck fully tightened up without the flex-joints it is pretty much totally solid - virtually zero flex, even with the chassis cuts.
I'm hoping that with the chassis cuts, and a variety of levels of flex-joints, I can vary the flex for different situations. What I'm trying to do just now is to get some way to measure the flex. (Torsional flexiometer required!). I have a sneaking suspicion that even with a fully flexied upper deck, the chassis is still going to be too stiff! At this point I'd say the chassis is probably similar to the standard alloy chassis and the plastic uppers. But possibly not as soft as the plastic chassis and alloy uppers.
Anyway, I want to have the car at a stage where at least I can try and adjust it at a meeting just by adding or removing some flex-joints. Could be interesting....
You going to Ayr?
