Brake discs Zimmermann or Duralast

Zimmermann Brake discs

Zimmerman coated rotors + OEM pads

Notably less rust on rotor edges and maintains the great initial bite of the OEM.

Pros: less rust, good bite
Cons: terrible brake dust

Zimmermann Brake discs

I went with the stock front 335i Grey 4 piston Brembo's (340mm rotors) and 2 piston Brembo's (345mm rotors) in the rear. I also went with stainless steel brake lines. I used the Zimmerman 2 piece rotors, I can't remember the pads, but I remember they weren't cheap. It stops really well for a daily driver.

Pros: stops really well
Vehicle: BMW

I have been driving multiple BMWs for almost 20 years and have always used Zimmermans as replacement rotors. I will keep buying them.

Pros: reliable, good quality

The online vendors offer Zimmerman/Akebono kits, I installed one on the front of my E92 and brake dust is nearly eliminated. The Akebono Ceramic pads might have slightly less bite but I'm happy with them.

Pros: reduced brake dust
Cons: slightly less bite

Duralast Brake discs

The EBC Yellowstuff pads didn't last as long as the OE pads. The Alfa EBC rotors still are shipping with Gen1 "ThermicBlack" coating on them, which isn't as good as the Geomet/Geospec coating that EBC claims to now be using on new production parts. The EBC Gen1 coating rusts and looks like a pretty nasty rotor in just two years. I went with the EBC rotors in 2021 because I didn't want Chinese parts either, and the EBC items are made in the UK (and pads may be made in the USA).So when I did the rear brakes again this year (rear EBC YS pads shot in 23k miles), I went back to the OE Alfa rear pads. I ordered the EBC rotors, but when they showed up with the Gen1 coating that sucks, I returned them. And I ended up having to buy Dynamic Friction Geospec/Geomet coated rotors, which are made in China. The Dynamic Friction rotors were well packaged (much better than the EBCs). So far, they're completely fine after maybe 100 miles.

Pros: good packaging, fine performance
Cons: short lifespan, poor coating
Mileage: 23000 km
