Spring choice and rear Sway Options

[Literati914]

Is there a point where a stiff(er) [than stock] rear spring negates the need for a rear sway bar? I've got a set of #140 welts that I'd been planning to use with or without a rear sway bar for sporty street car handling and probably some A/X.. but would jumping up to say a #180 spring and no sway bar be a better choice (both seem a bit much?).. or would it be better to use a stock rear sway bar and lighter springs?

Ok thanks for the comments guys.. So it does sound like a stiffer spring might work to 'take the place of' a rear bar, so to speak. Ok, maybe not, but the jist is that basically everyone agrees on a front bar but opinions differ on the rear. So that'll allow me to just weld in the brackets for the time being - save the money on something else the restoration will need. And I can revisit the rear bar thing later.

I'd mentioned #140 springs but actually I'll have 200,245 and 260 coil-over springs to choose from instead. So, I guess I'll try the #200 first. The rates do not change between the regular springs (ID) and Coil-overs or anything, right? Just wondering 'cause I never hear of anyone w/ coil-overs running anything less than like #180 or so.
