Brake discs Zimmermann or POWER STOP

I replaced the front pads and rotors on my F20 M135i yesterday. Same Brembo brakes as yours. I did a lot of research, and there isn't really "better" than stock for the same money. The only better option would be to upgrade to bigger brakes, but that would cost way more. I ended up going with Zimmerman Z-coat two piece rotors and ATE pads. The Zimmerman rotors are the slotted and dimpled versions. BMW calls that the M Performance rotors as OE. They're the same size - 340mm. They reportedly don't give much of a performance increase, but they weigh about 8% less than standard discs. All together with the hardware (guide pins, caliper bolts, etc) was about £500 with shipping from Spareto.

ngl i just installed zimmerman rotors and they probably had that too but no problems

I had Powerstop drilled and slotted on my Camaro for 70k miles, currently have them on my Silverado no issues

Power stop is great. I use their drilled and slotted rotors and ceramic pads on many vehicles.

I ordered zimmerman rotors and genaric TWR ceramic pads

I just did pads and rotors on my '19 Alltrack. I went with Bosch Quietcast pads and Zimmermann rotors from FCP Euro. So much better than the OEM I removed.

Zimmermann Rotors / IS2000 Pads

A few years ago, I put PowerStop front rotors and pads, and pad slapped the rears on my buddy's 2011 One Hundrert n' Fitty (and flushed his brake fluid and replaced it with DOT4 synthetic). He said it was the best braking feel and performance he's ever had in the truck, and he bought it with 6 miles on the odometer and had pads done previously. He's still using the same stuff, too, rotors are still well within spec several years later.

I've got Zimmerman rotors on the front and haven't noticed any difference from stock.

I also bought Power Stop Z23 Evolution Geomet Coated Rotors after I bought and installed Z23 pads. Desided I need to change the rotors after I installed the pads, oops. What bothered me about Power stop rotors is that the front rotors where NOT Notched (balanaced).
