torsion bars

Smaller bars will fail sooner or "loose their resistance to torsional twist" and will "sag" sooner. In a drag car this is not a big concern as they dont see alot of use, a daily driver would be a different story though as far as for a car with a big block or even a small block. I wouldn't run slant bars on either of those on a daily driver because they will give up sooner.
