Your assumption is wrong: a 23.5 torsion bar and a 250# spring will not give you 375# but 262#.

Thank you, it helps to know where you're coming from. So what you're saying is that a rear coilover spring is only 56% effective at the rear wheel? Does anybody know if that's true for coilover springs on their own, or only in combination with t-bars? Is there a different effectiveness coefficient for the springs on their own? Using that number, in order to keep the car balanced at 250# up front I'd need a 450# spring in the rear, which seems high to me.

Thanks,
Brandon
