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 have EBC rotors and Redstuff pads right now and am quite happy, but I had R1 and Powerstop previously.
Did a set of EBC slotted rotors and RedStuff pads on our 7.5 GTI and it's changed how the car brakes entirely. It's got a real consistent bite without bleed off.
I just installed front axle drilled and slotted rotors, and new pads, all from R1 Concepts, and total cost shipped (Amazon) was $56. Tax, delivery, shims, everything but silicone grease.
Was also thinking of doing EBC dimpled and slotted rotors, just to not worry about potential drilling rotor issues.
Got a 2017 lancer and did the R1 concepts. Good results after only the first two weeks. Mind you! I had two seized calipers in the back and had to replace those as well. What is stated about drilled rotors is true about the cracking if you’re using them aggressively, I bought these specific ones because I read they have the better rating out of most and since I’m using them in the winter I’m not concerned with them getting too hot to crack (please correct me if my logic is not correct) but I assumed that since the vehicle was primarily being used for cold weather it would be best to go with a more reputable brand for safe stopping power.
Got the R1 concepts for the rotors and pads. Impressed by the braking power
R1 concepts are fine not the best.
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.
