Brake pads Textar or GALFER
1st step, better pads for more initial bite and overall stopping power. Galfer HH can be had for $80 front and rear, you can spend a lot more on performance/track pads if you want the best.
I got Zimmerman rotors and Textar brake pads for my 2013 550i with the M package. Everything is been working great for the last 6 months.
At the shop I run, we use textar pads on Zimmerman rotors. For some reason textar on textar always make noise on BMWs ( we elevated our complaints all the way to Textar, and they sent a rep to finally shrug). Pagid pads are ok, but I find they wear out more quickly.
My go to brake pad is Textar. Why? Less problems. Since I own a shop, any warranty issue is wasted time. I will not charge a client to make it right. I do not have time to do the job a second time.
I replaced my front brakes recently with Textar pads and new Zimmerman rotors (non-PP brakes). Overall I am happy with them; I think they have a little more cold bite than the original pads do but are very similar to the stock pad compound. Original pads left deep grooves/ridges in the rotor around 55k miles. I don't track/autocross the car and I'm pretty easy on brakes. I also prefer and good cold bite which you don't always get with a ceramic pad.
I stick with oe (Textar). Work great for me.
I do plenty of track days and the OEM Textar pads are grippy enough, modulate well, and hold up just fine on the track. If you want something that's not loud on the street or dusty as hell, OEM is probably the best option

I have good experience with Textar pads, both epad and normal ones. Currently I have ATE rotors, but they had to be resurfaced because of warping, so no recommendation from me
I just switched from OEM (Brembo HH Sintered, I think) pads to Galfer HH Sintered pads. I forgot to scotchbrite the discs and I think I glazed everything up during bedding-in process. I used scotchbrite like mad on the discs and sanded the pads with 220 grit until they were dull like when new, but the brakes seem to have the same behavior - heavy brakes test after 10 mile bed-in ride, the brakes plateau without getting to ABS trigger unless I squeeze like a motherfucker. The previous pads I could stand up on the front wheel with one or two fingers, so I feel like I've done something wrong.
