Default Swaybar bushings

Has anyone spec'd a poly swaybar bushing for our cars?

It's my favorite mod since it's cheap and has a huge difference in response and handling.

Which bush do you mean exactly.. (Pic) We use different descriptions over here perhaps?

IIRC A lot of experiments with poly bushes have not been a huge success on these cars for some reason. The rear motor mount is a prime example and replacing the soft rubber bush causes huge vibration feed into the body..

poly sway bar bushings help reduce roll by holding the bar more firmly between the axles so they work more uniformly.

but don't look at me, i accept the mushiness of the car, as i already have a sports car that rides stiff.

I removed the front anti-sway bar and run stiffer springs. I don't think stiffer sway bar mount bushings would make much difference in the Insight... The linkages aren't very direct, the distance between the mounting point on the strut and the bar bushing mount point/fulcrum is long/not very direct - so the amount of slop and flex, etc. along that length is likely to overwhelm any reduction in slop you'd get by installing a stiffer bushing at the inside mount point... Something like that, just some theorizing... I like the no bar/stiffer front spring ride/performance better than stock...

I think you are correct sir. Our sway bars are too tiny to notice a difference from a poly bushing

So lots of opinions but no info on the original post.

I've installed poly swaybar bushings in the past, and it always makes the bar act like a larger bar. It's one of my favorite mods. Just wondering if there was an off the shelf bushing.

No. And they wouldn't make much difference anyway.

a lot of 'upgrades' for the G1 are owner made, but polyurethane isn't extremely difficult to work with, and with some measuring you could probably find something close that might be a direct fit.

most people start at the back end of the car, because it's got by far the worst suspension and upgrades there make big differences in the car overall.

We don't have a rear swaybar.

And idk why, I have no issues with the spring rates. My car drives/handles great, does not bottom out. >shrug<

if you watch insights race you will see how much roll originates from the back end.

here's a pic from bluesights autocrossing:
