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.
I might get scolded by the purest, but I went with these R1 Concepts on my 2019 X5.\n\nI too was shocked when the dealer quoted over 2k for brakes, so I started looking at options. I\u2019ve had them for about two years, they have performed excellent and they look amazing.
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.
I’ve ran the R1 concepts D/S with OE Pads, steel lines, MOTUL 660 fluid. I’ve got them pretty hot on mountain road runs many times, no issues.
I would suggest going to [www.buybrakes.com](http://www.buybrakes.com) and get the R1 Concepts pads for the front and rear. The ones Rockauto has growl a little bit.
I slapped in some r1 concepts pads and rotors on both of my Subarus after the oem ones kept warping.
just waring yall about this company.. they dont care about product quality and safety.. had an issue with my setup only 1 month outta warrty and they said pound sand .. they dont care .. brake pads are made in china and rotors now too.. the pads will fail you big time even if you have a daily driver... never again will i buy a product from them
