I have spent way too much time looking into what I want to do to my 2023 Forte GT 6spd and can never find the info I want a month later. Because of this I am just going to put all the info in this one place. Everything I am going to list is my personal taste in how I want my vehicle. Since I am over 50 I don't want something low that sucks to get in and out of or that can't handle a pothole. I also don't want to draw the attention of police with too much noise. I want everything I do to be easily reversible in case I need to use the 10/100 powertrain warranty.

Spark Plugs - stock 18849-08080 (NGK 97080 - SILZKR8E8G) heat range 8. If I ever change from stock it would be NGK 1422 - 1LKR8E6 (heat range 8) or NGK 97312 - 1LKR9Q7G (heat range 9). Gap ranges from .025 (n75 tuned) to .031(stock)

Lower mount bushings - helps with wheel hop. I have one of the Whiteline KDT970 in the rear spot and one of the yellow Powerflex PFF26-120 in the front position. Using both Whiteline creates too much vibration for me and both Powerflex are not durable enough. - Done

Nice! I should really make a build thread for mine too. Keep having to go back through a bunch of threads gets annoying.
Since your car is a 6 speed, I'd highly consider the Powerflex engine and transmission bushing inserts, Powerflex PFF26-125 and PFF26-123. Completely transforms the clutch feel and doesn't add any vibration.

I have the Whiteline black lower bushings now and I get slight vibration at idle. I am going to swap to the yellow Powerflex next month to see if that helps. I am worried that adding more bushings will increase the NVH that gets into the cabin at idle. Thoughts?

I went through like 3 lower engine mount bushings trying to find the perfect combo of NVH and clutch/shifting feel, and then got the Powerflex lower bushing and it was perfect. Less clunking than the cheap Amazon one I had, and less vibration than the Whiteline, so much so that I only noticed it in the summer at idle with the AC on. It quickly broke in to the point where I can now only barely feel it in the brake pedal with the AC on. Stock levels of NVH with AC off or at higher than idle. With the upper mount inserts, no extra vibration over that, but even better control and feel with far better controlled engine movement and very little drivetrain slop. Highly recommended - the best mod I've done to my car, after the Boomba short shifter

Added to my list of things to do. I think these sound like I should give them a try. They are not a ton of money. You should do a build thread for yours. Be nice to look one place for things.

After seeing a few issues with Whiteline rear sway bars and Whiteline endlinks breaking I decided I should stick with what I know - Eibach REAR ANTI-ROLL Kit (Rear Sway Bar Only) - HYUNDAI Elantra GT 1.6L Turbo Hatchback (eibach.com) I am going to go with the Eibach 22mm rear sway bar for that reason along with a couple others. I am not a fan of the stress the second set of mounting holes cause on adjustable bars and I do not like the clamps that have to be added to some to keep the sway bar centered. The Eibach design has the stops formed with the bar and is not adjustable. Here is a picture of a 22mm Whiteline bar that snapped on Veloster.

Yep... I shredded whiteline front end links in 10k miles... no way I’m going to trust their ballpoints.

Looks like a combination of car too low and incorrectly installed rear sway bar.

If you look at that swaybar the metal inside looks like sugar.. I think the heat treat went wrong.

Could be....but I'm sure the owner of this sway bar lowered his car excessively and cheap'd out on not getting adjustable endlinks. It looks like it was binding. That car must have been very bouncy and rough on the street. Had mine for 3 years. No problems.

Eibach sway bar came in today. It is a little pricey but I am willing to pay it for a high quality product. I love that this only has the one hole in each end which I feel is stronger than the ones with two holes. I also really like the collars that are part of the bar to keep the bar centered. I am not a fan of the clamps like Whiteline uses. The hold downs to the subframe are also a stronger design since some of the steel flat stock design can break over time. And the last thing is how the Eibach bar is formed with the curves like the oem bar.

Where did you get the Eibach sway bar from?

The Eibach website SUCKS! I try to find the sway bar and all I get is springs:
