Reviews of R1 Concepts brake discs

I upgraded our outback and ascent to the R1 concepts and haven't had any warping issues yet.

finally got r1 concepts put on about 5 days ago. drilled and slotted rotors. SMOOTH like butter

R1 concepts are fine not the best.

Ive got r1s on 3 of my cars and love them. Put out a decent amount of brake dust so either learn to live with it or youll be finger banging your wheels to keep them clean. Working on set #2 on my camry, lasted about 40k miles but i drive hard. Handled well thru the mountains

I went with R1 Concepts for the front..thats with slotted and drilled rotors and pads and im happy with them. I've run them about 6k miles so far and no issues.

I was more than happy with my R1 Rotors at Sonoma 2 weeks ago. I felt a bit of pulsing when I got the brakes especially hot, but I never had any real fading.

Installed new r1 concepts drilled and slotted rotors. After break-in, I noticed a clicking sound from both front rotors, resembling a wheel of fortune. The sound happens when a pad is in. The r1 concepts rotors are dimple instead of drilled all the way through, unlike my previous Power Stop rotors. Brakes feel great otherwise, but this pesky clicking noise when I have windows down will drive me nuts. I may go back to Power Stop.

I’ve ran r1 concepts drilled and slotted rotors for like 3 years now with stoptech pads and never felt the need to upgrade higher than that for just dailying/spirited driving

I run r1 concept rotors with ebc red stuff pads and they work great for me

I installed R1 Concepts slotted on my 13 R/T years ago. They are better than the brakes that came from the factory.
