I have used these R1 rotors on my past 4 vehicles... all cars around 3500-4000
lbs. And approximately 325-375hp.
I have always used EBC Red Stuff pads. Normal daily and occasional spirited drives, I would get approx. 40k miles per set of pads.
No squeal issues. No chatter issues. No cracking. No separation from backplates... and very low dust. Even with drilled/slotted rotors.
Your experience may vary...
