2007 F1 Front Suspension?

[rcr286]

Does anyone here have insight into current design of F1 front suspension? When I saw the Toyota TF107, the front suspension angles stuck out like a sore thumb...then when other manf. release their cars, I saw that they were all the same!

The top control arm angles down from the the top of the chassis to the hub, and the lower control arm now mounts to the nose cone and is angled down as well...more excessively than the top. Of course, this will still give the desired camber gain, but what about excessive track change, roll centers, etc?

What rules change, or design philosophy has brought this about? (note; when looking at side views, you can see that the nose cone does not have any extension to the bottom of the car until it meets the chassis near the side pods...no verticle splitter to mount lower control arms to)
