10th Gen. 2018 Honda Accord 1.5, does anyone no what size rear sway bar is on the 2018 Accord 1.5?

Here is the info from my 1.5T Sport off of Honda Canada Owner profile.

Yes most specs are the same, but an LX and EX-L (no EX offered in Canada) have smaller front and rear sway bars. See picture of Canadian brochure.

Would definitely make it stiffer. I would imagine the sway bar comes with new bushings to compensate for the increased diameter.
