Brake discs R1 Concepts or Raybestos

I went with Raybestos for the rotors and pads this time since they’re a brand I’ve used before and trust for consistency.

For rotors, raybestos is a solid bang for your buck and I haven’t had any problems with them

I have used rotors from R1 Concepts for over 15 years, on vehicles ranging from a Dodge Caravan, Chevy Trailblazer, to multiple BMWs and have never had an issue. They’re high quality and good price and I highly recommend them.

Its been just under a week after installing R1 Concept's Geomet drilled/slotted rotors and ceramic pads, I am impressed. Extremely quiet and smooth ride but once they're hot, they get aggressive.

I bought R1 Concepts front rotors for my Lexus IS250 at 85k miles. My car sits at 143k miles 5 years later and they have been the BEST rotors i have ever used. I chose their Geomet coating, and they are so rust resistant it is ridiculous. I have zero rust on the veins or hub of my brakes at all after all this time. I have used Powerstop rotors in the past on numerous vehicles, but I find the zinc coating will always rust after a few years. The R1 Concepts geomet coating is the best in my experience.

I have R1Concepts Geo-Carbon series rotors (2nd vehicle I’ve used them on), absolutely no complaints from my Giulia. I’m rocking them with Porterfield R4-S pads and the bite in dry is very nice and feels the same in wet.

R1 concepts slotted drilled rotors and pads along with some GoSpeed traction drop springs and alignment.

OEM rotors rust like that in snowy areas, they look unevenly worn. If it gets a little worst you’re going to replace the pads and rotors. Ray bestos makes pads/rotors coated with zinc that won’t rust like the OEM ones.

R1 concepts are fine not the best.

Get Advics as they're closest to OEM money can buy, stay away from Raybestos i've had nothing but quality issues when I got those rotors.
