My Ultra Racing rear sway bar install

I'm used to it now, and the back end tracks very well, now. I'm very happy with my purchase!

Don't like to do this, but the way you're describing this is incorrect, and misinformation spreads like wildfire on the internet, so...

If anything, adding or increasing the size of a rear swaybar (or otherwise increasing rear roll stiffness in any way) will tend to make the back end of the car "step out" (oversteer) more in a turn, not less. Remember, a rear swaybar is transferring weight from the outside rear tire to the inside front, it's giving you LESS grip in the rear... but that's generally not a problem in a FWD car.

Perhaps you're referring to body roll? The car will certainly roll a lot less with more rear roll stiffness, and as you said, it will feel a lot more planted.

BTW, Garm sells two different Ultra Racing bars, a 19mm and a 23mm. Which one is this?

I think he means he used to specifically push it into understeer on the on-ramp, and would aim 'too shallow' to compensate. He has enough grip now the car's going where he aimed, which was still 'too shallow' which was now a problem.

Well funny enough when I ordered a month and 1/2 ago only the 19mm was available so that's what I got. As far as the whole stepping out issue, I am big proponent of preventing misinformation, so I understand why you posted this. I'm not sure how a rear sway bar transfers weight to the inside front wheel, but I'm just saying how it feels to me. The back end used to hop around every time there was a bump or dip in the pavement. The back end has calmed down, now that I have my sway bar on. Maybe I'm wrong and maybe I haven't pushed it enough to tell the true difference before and after. It seems to me, that it transfers force from the outside rear wheel to the inside rear wheel, allowing less body roll and keeping both rear wheels more firmly planted.

Now I'm not an expert, nor do I claim to be, so I would like to know if/how I'm wrong. I'm not too proud to believe I'm always right, so please let me know if I am in error.
