I just ordered some for my 2020 AWD stinger.I had the eline rotors on my last car for 3 years plus and 20k miles and they worked great.KIA is going to put them on.The geomet is a step up from the eline and if they work as good--I will be happey.They felt like stock brakes on my last car--a very rare type r crosstour--and honda did the same thing KIA did--they put on a honda performance brake caliper and pad--but a stock rotor--once I upgraded a few things.Stopping distance was much sooner.Bad weather performance was way way better--they would bite even in bitter cold or in pouring rain--no slippage even when soaking wet.The old honda rotors shook when braking from high speed on the hwy(but car was very heavy)--the R1 eliminated that also.They were also quiet like stock brakes.Also the stopping power was so good--that the few times I had to emergency brake--the ABS never went on--the car just stopped.They looked great.Brakes were so good that yearly I tested them in snow to make sure the ABS was working and it was.Also 2 years ago going about 45 the guy in front of me slammed into the next guy--his car stopped--I hit the brakes and stopped 3 feet behind his bumper--no ABS came on--so it saved me from a wreck because of the power.I had the rotors on all 4s and the geomet are supposedly better.if you can wait I will have them installed and put a video up in the next few weeks.Igot all 4 rotors for 359$.The fact that we already have Brembo calipers and pads--these R1 should work fanatastic with our stingers.My experience--most of the folks that have problems have installed it themselves, I am going to let KIA do it, service advisor also is curious to do this and feels it will make a huge difference.Cons--my rims got a little dirtier with my last car--but I had absolutely no clue to what pads were on there--they were honda euro spec performance pads that they put on this car with the R1 rotors and a euro honda spec brake caliper.--seeing as only like 5 crosstour type R's were built--I have no idea.My crosstour was a 2010 that was an AHM--American honda motor car--that I bought directly from honda.I traded in the car 2 months ago, and KIA even complimented on the car.BTW my 10 year old honda braked slightly better then the new Stinger--so I had to upgrade and believe this will make the difference.I thought the stinger had Brembo brakes--but the rotors are not performance, which is misleading.I also lightly tracked my last car and had no fade--rotors after 3 years and 20k miles looked 95% new--pads with 20k miles were at 75% still.So the mix of honda type r euro brake calipers and pads with R1 rotors made a huge difference--and should do well on the stinger.It is hard to compare because my honda was made for me and I had no actual stats on the brake system other then it was a level 1 honda euro light track use brakes, But the rotors from R1 made a noticeable positive difference.
