'longitudinal' sway bar?
'longitudinal' sway bar?
(OP)
I was wondering if a 'sway bar' conected front to rear on one side would give an advantage on circle tracks where you are braking and turning. The idea would be to transfer weight to the inside for braking when the nose dives , and maybe it would help with powering out also.
Screwy idea? Illegal?

brake
load on front tires increases
antipitch bar (which will work just like antidive, but slower) starts to take effect
load on front tire increases, braking increases (good)
driver feathers off brake as he feeds in steering wheel
weight on front wheel reduces
car doesn't turn
Oh dear.
On average, around a circuit, ignoring aero, the vertical load on each wheel is unchanged by any internal reconfiguration that does not move the CG or change the weight, wheelbase, or track. So you can generate short term changes in the load on an individual wheel, by any number of methods, but at some point you'll have to pay it back.

If it was a very short sharp corner, where you are almost still braking right into the apex, then going straight to power (it would have to be more like a hairpin) this could be of benefit, as you would gain on front grip into, and rear grip out of the corner.
