I bought R1 Concepts vented and slotted rotors and EBC Yellow stuff brake pads. This is on my 2021 AWD Turbo. I still got more break in to do, but the difference is huge and immediately noticeable.

I’ve been running these for a few years….much better than the stock oem
These guys make great stuff and their customer service, if you need it, is exceptional. Only thing I put on my cars. My Mazda CX5 has drilled and slotted rotors, and my 13 C70 has slotted rotors. I will probably go with the Geo Carbons when my S60 needs them as I talked to a V60 owner that had them and he said those were the ones to get.
Absolutely normal. But I would still get one which is coated. My R1 Concepts from Rock Auto were completely black with a Zinc coating
I’ve got the R1 concept drilled/slotted rotors and ceramic pads, felt a decent difference from the OEM but my rotors and pads were at about 35% life so it makes sense that I’d feel a good difference. I do some spirited driving around town and the brakes perform pretty great.
Bought my 2018 Stinger GT new - within a few months my steering would shake like it had warped rotors - and it wasnt always the case - it would be ok at times, then come back. I use Auto Hold a lot - and it seems that feature causes the shaking in the steering wheel the more I used it. I did talk with Kia about it and they dismissed it and said it was fine - after being sick and tired of the shaking I went and bought new rotors and pads from R1 Concepts and havent looked back - no issues at all since I installed them and I use Auto Hold every single day.
If you have no interest to do anything other than normal driving r1 concepts will work. If you so much as do a little "spirited driving" they will bake and turn into crappy brownies. And refuse any type of refund even with 500 miles on them. I honestly preferred OEM. They lasted a nice long time, minimal noise, and they were actually really nice on track
R1 concept is what I use, with the drilled and slowed with there performance pads, works very good and at a low cost , plus the rotors look awesome on the car.
Been running r1 concepts slotted and drilled for a year on factory bbk. Highly recommend.
I have R1 Concepts slotted rotors and ceramic pads, huge upgrade in performance over the stock setup.
