A place to discuss the characteristics of the cars in Formula One, both current as well as historical. Laptimes, driver worshipping and team chatter do not belong here.
I think all these different geometries resulting from the upper wishbone's lowermost mount point (remember the different 'mounting slot holes' covered by a panel for the front suspension that we saw in Bahrain testing, and how Allison said, it's to 'cover' all extreme setups ? probably the same facility existed for the rear suspension as well) since Bahrain itself, for both front and rear wheels ; and hence don't need to be declared. Or perhaps the sheath over the suspension arms or the body work changes related to mounting it a different location doesn't count as 'aero change' (only visible aero changes need to be declared for the 'show and tell' on thursday) .
