Swaybar for regular driving?

IMO I think that money could be better spent on performance shocks/struts to match your springs. This greatly increased the handling on your car especially at high speeds.

The sway bar is a good mod but for $400 and just regular non spirited daily driving you wont notice a big difference, just a bit more stability in the highway. If you drive hard and cornered hard during your drive then I'd say it's worth it

Another post indicating fundamental mis-understanding of the Yaris/Tercel/Rabbit rear suspension. (That "solid beam" is soft in torsion) The Y/T/R rear suspension is IRS with integral sway bar function. Another way to describe is that the sway bar serves locating function...where one or more lateral links or A-frames serves only locating (no spring) function. Another example of this is TRUE Mcpherson strut front suspension (in circa 1980 Mazda GLC), where a sort of normal heavy looking front sway bar locates the bottom of the strut/spindle carrier...thereby serving both locationg and springing functions in one piece.
So, Yaris has anti-sway at both ends.
91 fwd Corolla Wagon has no anti-sway, and softer spring rates. Works fine in all driving I've done. Just doesn't feel like a go-cart. Maybe better than Yaris on the high-crown gravel roads. (If anything I could see adding some light anti-sway at this Corolla's rear only for better peg-leg-differential traction.)
Corolla got a version of this suspension after Tercel. (Stated reason was improved trunk space.) A circa 2005 one I saw had a visible solid bar inside a U-shaped channel for the cross beam. Tercel had just the U. I think rabbit had a T-section. Looks like yaris has a closed tube in a shape that is relatively soft in torsion?
