Just to add to the complications, as Jac points out, you cannot compare steering turns lock to lock between different cars/manufacturers which have different pick up points, geometries, wheels and tyres. For instance, I do know that my Southern GT has a tighter turning circle than a GTD.Ok. More complicated than i first thought.
Thanks Mike, thanks Jac. I have written to Kiley Clinton and waiting their reply.
Meantime even 2.25 lock to lock would be ok (provided improved turning circle).
I will Keep you advised if I learn anything new.
