I run the Swift front and rear set.

I don't think many are running the full set. It was not that bad of an install. At my shop it took only a few hours.

Swifts are actually thinner(lighter), but its a stronger/stiffer material. So they are not judged by mm. They are 18% stiffer up front and 20% stiffer in the rear.

Keep in mind, a swaybar is only used when cornering. When driving in a straight line they are not even used. This is why it's a big item for tracked evos; to take care of the turns better.
I have run a larger RSB; a 25mm adjustable Hotchkis both on the track and on the street. I liked the feeling of it on the street personally. If you do go big/thick and stiff, be careful gunning out of tight turns when it's wet as it may induce extra oversteer!

what is a good pair of bars to get that will it make it so the sway is kinda gone but prevent extra oversteer (aka *** end kicking out)

^ does progress only carry 27mm sway bars, i've only seen 25mm at most. Is longer necessarily better?

It's thickness, not length. And no, thicker isn't always better. Too thick in the rear (ewww) and you can start lifting inside rear wheels.

It's nice to balance a bigger rear bar with a bigger front bar. The front bar just sucks to install but it's worth it!
