I have had EBC blue stuff for 3000 miles and haven’t really had any problems at all. The only problem I had was some wheel vibration after some spirited driving / braking. Today the whole car was shaking and I was feeling as if the brakes were kicking in on their own during hard acceleration. This is with all driving assistance off. I looked at the rotors and this is what they look like. I really just want to know if this is normal, or did something go wrong on install I never notice or is this an issue with the pads

Heat spotting. Here's some info on it.

Yes but is it normal ? On a m3 seems like other people haven’t had problems like this at all, would EBC yellow stuff give the same problem?

Did you follow this procedure when you first got them?

Not normal. Try rebedding the pads again and see if the pad transfer layer is more uniform and with less heat spotting. It may take more time driving (braking) on the pads before all of the spots are removed.

I think these are past re bedding I just reverted back to stock pads.

They look glazed. You can clean them up by using sand paper to remove the glazing. You likely got the pads too hot too fast and exceeded their temperature limit. The pads are salvageable.

Some of the cracks are all the way through, I would rather not, thank you for the help though

I understand. Safety is key and you certainly don’t want to thinking about the condition of your pads every time you’re driving.

I have the EBC blues on mine for about 4k kms now strictly spirited street use and they are working very well. I also have upgraded turbos on flex fuel tune. Loving that the cold bite is noticeably better than stock and when it's heated up with back to back WOT pulls, it brakes light years better over stock. Curious was yours used on the track?

Never used on the track just a lot of spirited driving, I use this m3 like a mad man

They will perform at their best in aggressive spirited driving and some casual track time.

The way I use the breaks and the way I use this car, it’s constantly like im on the track, so I’m suprised these brakes didn’t holdup, I’m going to contact ebc and hope we can work something out

Looks like you heat checked the rotors. You got them too hot.

that makes sense as to why the rotors look like that. Did reverting back to stock pads fix the problem? I can't imagine the stock pads can handle brake temps better than the bluestuff. Also you may want to look into upgraded rotors like the EBC 2 piece floating ones

Yes the brakes seem to handle way better even doing the same sort of driving than the ebcs. I’m surprised I was able to over heat the ebcs and not the stock ones. Feels like something is wrong

Doesn't sound like you've ever been on a track if you think you can drive on the street like that.

I have, and I drive on the street like a maniac, I’ve been to the canyons aswell. Arizona is a different place when it comes to driving. Especially for me.

I am keen to hear what EBC has to say about this. Did you experience better braking bite and performance with your EBC blues as compared to the stock pads?

Suprisingly no, when I put the stock pads back on they felt more responsive ebc hasn’t replied yet

A lot of people confuse the fact that the stock pads leaving a lot of brake dust makes them a bad brake pad.

The stock pads are actually a fantastic hybrid pad for street and "canyon" driving, even on track. They'll wear quicker but certainly better than this.

Get new pads or reinstall install the stock ones. I wouldn't reuse those pads even if you cleaned them up. I would also take some very fine grit sandpaper and gently rub the hot spots, followed by wiping down the rotors with towels.
