So both my GT's have slight warping from high speed braking. It is not enough to get too worried about but I might upgrade if I can come up with a good replacement. 20yrs ago a bunch of us were upgrading our 2001-2006 Elantra's but the front rotors were too small and warped trying to exit the highway in a spirited way. I actually worked for a Hyundai dealer and figured out how to make Tiburon brakes work but it was kinda costly (I also figured out the Tib rear sway bar swap and was selling them to people around the country). The next thing I did was send a few sets of stock size centric rotors out to get them cryo treated. Once I put those on my car I did not have a problem with the rotors warping again. I was not interested in slotted or drilled for several reasons. There does seem to be a couple cryo treated options for the Forte GT but they want $120+ per rotor. All the front rotors listed for the 2018 Elantra sport and the 2020 Veloster turbo are the same 305mm (12inch) as well.

What I am wondering is if anyone has tried high carbon rotors to reduce the heat induced warping. There are a couple choices for these.

Also I noticed that there are high carbon or cryo treated rotors that seem like they will fit non-turbo 2019+ Forte's based on some cross referencing

I haven’t tried any upgrades but already can feel the effects of that warping at like 8000 miles under hard braking.

My FE has a slight warp too. Going to do this mod when the pads wear out:
Interesting big brake mod using Hyundai OEM parts.

These were on the 2007 Tiburon SE. Aluminum with "Hyundai" machined on it, they worked great even though single piston.

This is everything I found, I am going to try the Brembo high carbon first, if those warp I will go to the Centric Cryo treated. The Raybestos high carbon might work as well.

You should do fine with the brembo, they do make pads for their rotors. I suggest buying it as a set if you can.

Nothing for the front pads from Brembo that are not ceramic. My personal experience with pads is that anything with ceramic warps rotors in half the time of oem pads. I generally use oem pads with upgraded rotors to cure oem sized rotor warping. I did have good luck with Hawk pads in the past but they did dust pretty bad. Unfortunately Hawk does not make front pads for this car.

I've had great luck with EBC pads. Yellowstuff is fantastic and grabs crazy hard, and dust like mad. Redstuff is low dust ceramic, stops pretty well. Haven't tried the others

I think if I was to try any aftermarket pad it would be the EBC green. Maybe when the oem pads wear out I will try a front set.

Do some research and draw your conclusion, you may want to see if removing the dust shields will help your situation.

True, not sure I want to do that in New England with all the salt and sand in the winter but it is an option. I like these RS3 add on ducts. Pretty sure a couple or Veloster people are using them. I wonder if I could Macgyver something similar for less money.

That reminds me - I actually have a set of EBC green on my Land Rover. Forgot about that since I did it so long ago. They're... ok. The truck still doesn't stop great, but that may be more the tiny factory discs than the pads being mediocre. Very low dust, I will say that.

I did this over a year ago. It's close enough to fit just right like a Audi control arm. I got the idea from the VW GTI forums. I noticed the VW/Audi control arms look very similar to our control arms.

I knew I saw this on a Kia or Hyundai somewhere before. Good find since our stock brakes are too small for braking over 80mph

I tried to find EBC for my GT, but was unable to verify 100% they fit. Ah, Hawks are the best.

Since you have your oem front brakes off can you verify this is the correct front pad design? I am talking to Hawk technical support trying to see if they have an application that fits our cars that is not listed.
