For the F30 there are published articles about all the different compounds, and how M Sport and M Performance compounds differ from non-sport. For the 5 series I've seen nothing but online conjecture (from myself included) and, for years at least, everyone will swear that nothing changed with OE formulations but they clearly went to ceramic prioritizing low dust over braking. Apparently no one with any shred of sporting inking drives a 5 series or they have the sense to get an M5
As I said, I went out of my way to try to find old "E Series OE" formulations last time - looking for lots of dust and better braking. At the time (Pre-COVID) I posted and asked at several of the major Euro parts places and no one knew enough detail to confidently help me.
I ended up with
Pagid 34116850886 in the front and
Textar 2456101 / D1473 in the rear. I lucked out and they seem to be the "old OE" dusty compound I was looking for and more to my liking but either I need to re-bed them more frequently than I should have to, or perhaps I should still be looking at something aftermarket.
To come back on topic: I was eyeing EBC but I'm unsure which compound and this thread caught my eye. I wouldn't want to end up with rattling pads or other issues just to try EBC.
The best way I can sum it up: good cold and initial bite but I don't see the progressive increase in brake torque with increasing pedal pressure that I should. Oddly, when DSC III "brake ready" is operating they usually work more to my liking. In general the car stops, probably better than most of what's around me, but when I step up to doing something fun or encounter an emergency situation what I expect to be there isn't there. Similar to how factory throttle curves in Sport+ lead you to believe you have a monster racing machine but the bottom half of the pedal travel is essentially non-functional because you reached WOT at 50%. (I set linear throttle response with my flash tune to stop that nonsense.)
I loved the brakes on my E90 328 which were all OE and I wouldn't change a thing. Good cold and initial bite and heaps of stopping power when you got deeper in the pedal, easily able to lock PSS on hot, dry pavement if needed.
