I have 2018 GT. First went to Kia thinking the rotors are warped. They said they're fine. So I put on S.S braided lines. Not really any difference. I bought dimpled and slotted rotors just for the front . A little better feel but I should have replaced the back should too, I didn't have the money at the time. I heard about the Stinger forums and ppl were saying change the pads. I did that with a set that had the bevel cut but didn't help much. I was about to get the rear rotors replaced with the dimpled and slotted when Brake Performance was offering a 60% discount on rotors. So I bought the drilled and slotted for about $400. I just installed them last week. Bedded them in correctly before putting some stress on them. Today I was running up to 100 and braking hard to 30 several times and now it's night and day difference. No more pulsating. Got them so hot i could
smell the pads so I know they were worked. The dimple and slotted rotors might have resulted the same but I found that deal and couldn't pass it up.
