Aero grip vs. mechanical grip (and low profile tires)

Here are our CFD links and discussions about aerodynamics, suspension, driver safety and tyres. Please stick to F1 on this forum.

Milliken "Camber Car", perhaps - but I wasn't advocating that solution in my previous post

That DAX suspension seems to add a lot of complexity to effectivaly replicate the kinematics of a beam axle.

A beam axle without the both unsprung weight and what seems like the disadvantages of not being able to change camber at all. According to the article this system can still change camber if desirable in roll profiles simply through the use of unequal length wishbones. Am I correct?

I think both Milliken's car and Dax are trying to solve a problem that radial tires don't really have. Crossplies had about 4 times as much camber thrust as radials.

I think they were also missing a big point...The conditions the tires see at turn in is much different then mid corner.

The Dax appears to be somewhat similar in concept ( turned 90`) to this racebike rear suspension tried some 40 years ago..

Do any of the Caterham 7 - 'De Dion' type rear suspension units - allow for a negative camber set-up, fixed or adjustable?
