School me on Splined swaybars

[62fairlane]

I am thinking about running splined racecar style sway bars on my car. most of this has to do with not knowing the EXACT stiffness I want (paper and real life are two different things) and it seems like it would be a little more handy to have a bar that can be changed out fairly quickly (IE drive to the track and swap bars)

one question I had was that most bar ends I see are straight and not angled outwards would it be ok to bend the arms outwards to get them as close to the BJ as possible while still maintaining tire clearance?
