Not try to question you in any way. I'm just curious why knowing the number is so important. I don't see how I'd be able to achieve any more caster with the components I currently have even if I knew I was low. Although I guess it's possible to end up with more than I think I have. What would the drawback be of too much? I know steering effort increases which I'd probably welcome with the power steering. Is their any detriment to the suspension components if it caster is wrong?
