Brake discs STOPTECH or R1 Concepts
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.
daily driving, you can get a full set of bosch pads from rock auto for ~60$. I like stoptech slotted rotors to help get debris off the pads. they also hold up a bit better than standard blanks. drilled rotors are mostly for looks and can crack much easier under heat unless you are spending big bucks on a high end rotor, which imo isn’t worth the cost.
I have the Stoptech Z23 slotted and drilled rotors with carbon ceramic brake pads. Overall, I’m happy with them. The biggest complaint is that they use undersized brake pads, which is a feature that performance pads have in order to accommodate expansion under high heat. Because they’re undersized, when you brake in the opposite direction that you brakes last, they will “click” as they shift slightly inside the caliper. They don’t do it while driving unless you change direction, but I would have considered less aggressive pads if I knew they would do this. That said, I have had zero issues and great braking performance in spirited driving and emergency braking, over the last 45K miles or so.
I upgraded to stoptech drilled rotors with the posi quiet pads. I'm happy with the performance on street for spirited driving, and they create much less dust than my old Hawk HPS pads.
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.
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.
I use stoptech cryo slotted rotors front and rear, stoptech stainless lines front and rear, and stoptech sport pads and I have been very happy. No squeaks, squeals, and very little dust. After my last track day they did go a little wonky on me but I took an afternoon to go get them a little hot again on a fun drive and they straightened out for me. No vibration/wonky wheel ever since. They have worn nicely and I had it all installed back on Aug 3, 2017.
At ~4,000 miles, I bought a set of StopTech (front) drilled+slotted rotors (non-PP) for my GTI and kept my OEM brake pads. Everything was fine up until recently (~2,000 miles later). I now hear a high pitch "squealing" noise at very low speeds. This happens right when I'm about to come to a complete stop (1-3 mph).
