The bar itself is straight and usually splined each end to accept the bar ends which are essentially levers that connect via links to a unsprung part of the suspension somewhere. There are versions made for using on the rear suspension of a drag car which look like they could be adapted to work on a Z car, at the front of course. But finding info on the wall thickness of the hollow bars used is like a Wikileaks exercise only harder.
Maybe someone here is using something similar on their race car that suits, if so tell us about it. I'm plain researched out.
EDIT Maybe a mod would like to move this to suspension.
