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?

Best practice for stock front is 140 rear. Rear sway bar is a preference. Some people don’t like rear sway bars because it causes the front tire to lift on hard corners. Easy to remove a drop link at tight auto crosses.

A rear bar never causes the front inside corner to lift up. A very stiff front bar will do that though.
The problem with a rear anti sway bar is that it causes the inside rear tire to lose grip on corner exit, with a corresponding lack of acceleration when it's needed most.
