Brake discs EBC or OEM BMW

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.

Was also thinking of doing EBC dimpled and slotted rotors, just to not worry about potential drilling rotor issues.

Full suspension upgrades - this car handles like a dream! new EBC racing/red brakes with drill/slot rotors.

I installed EBC slotted rotors and EBC yellow stuff pads about 3 years ago. I did both fronts and rears. Granted Ive only put on maybe 10k km (6k miles) since then. But stopping power has been fantastic.

My 24 OBW was suffering from the warped/pad transfer front rotor issue so I swapped them with EBC pads/rotors and they feel and perform great. I had this same setup on my 22 WRX and I was very happy.

I’m seeing some very small cracks on the cross-drilled holes. At what point does this become concerning? These are the front rotors on a new G82 M4 comp after about 6 track days using Pagid R29 Yellow pads which I’ve used before with no issues. My preference is to keep the stock rotors rather than switching to non cross drilled rotors

I had this when I fitted ebc discs on my Cupra. It's went on for a few hundred miles but then went away. I think it's something to do with the grooves. My thinking was they maybe had a little lip or something that eventually smoothed off.

For example on my 4 series if you took it to a dealership to have the front disks and pads done you are looking at over £900.

Those BMW CSL drilled rotors suck. They came\nstock on my e85 M & they cause horrible pedal pulsation. I did a very deep dive on this after multiple sets & replacing multiple parts & checking everything 20x.\n\nThe bottom line is, those rotors are very susceptible to unlocking thickness variation or warped rotors secondary to water getting in the holes & corrosion forming around them.
