Packaging is a problem for tranverse leaf, though not insurmountable.
Where would you fit the damper ? WHen you take out the damper weight a spring of modern materials isn't that heavy.

The graphics are excellent and get over how it works as a spring AND anti-roll bar very effectively. Good job

Also, it's correct to say that you can alter the spring rate somewhat by moving the anchor points and altering the compliance at the pivots, but that will also affect the anti-roll bar component. It woudl require a much more complex sliding-sleeve on the leaf whci then creates stress points, so no real solution.

Has F1 moved back to coils? I thought they were still using torsion bars. Where I could see F1 using a leaf spring would be as a flexure based suspension pivot. It would have the benefit that you have no static friction in the movement (F1 cars already use flexure based joints in the suspension for this reason). It would also avoid the off axis loading issues that coils have when placed around a damper. Of course F1 teams have dealt with this in the past by using things like the Hyperco-ICP pivoting spring perches.

I do see the issue with changing anti-roll rates while changing spring rates. These are factors that aren’t an issue for a manufacture where you don’t have to spend as much time thinking about how hard is it to adjust this suspension on a weekly basis.

PS: Thanks for the feedback!
