Springs will bring nowhere close to the handling improvement of upgraded sway bars.

So no, the same improvement cannot be had with a set of springs.

 

I would actually be VERY interested in purchasing one of these. I don't like the way my RX takes corners at all. If this would allow me to take corners faster, like a car, I would be interested in one as well. how much did you say, $500? The price isn't very attractive...I would have to see how other people liked theirs first. That is a lot of money to spend, but if it does what it's supposed to do, I think I could do it.
