It's actually an excellent idea, thinking about it and I will probably adopt this simple but effective way of incorporating an all weather automatic geometry adjustment device.
Surely you all must see the logic behind this?
Wood absorbs moisture and expands when wet. Are you with me so far?
It contracts as it dries. Yes?
So, if you're on track and it suddenly begins raining hard, then wooden strutbrace increases in length and pushes the turret tops outward, so applying positive camber on the wheels.
When it stops raining and the conditions dry, the wood dries too, contracts in size and pulls the turret tops back inward, this time increasing negative camber for harder cornering forces.
Simple but extremely effective.
Next should be wooden anti-roll bars to operate on the same principle. :roll:
Handle every stressful situation like a dog. If you can't eat it or hump it, piss on it and walk away!
