Brake discs Zimmermann or POWER STOP

In July 2018, at ~124,000 miles, I put new PowerStop Geomet coated front rotors and new front PowerStop ceramic pads and rotors on a 2011 Honda Odyessy, for an owner who was about to move to into the rust belt (they were worried about rust so wanted coated rotors). OE rotors were warped and had very bad vibration at all speeds when braking. As it happens, the owner moved back to my area in 2023 and the car came back for routine service at ~178,000 miles. Pads about ~40% through, coated rotors showing no signs of rust, and despite the same person (his wife) driving the car with the same behaviors that apparently warped the OE rotors in the ~50k miles from when they first bought the car, 50k miles later and no signs of uneven rotor wear or warping. The PowerStop Evolution ceramic products have been great from my experience. The important thing with new pads and rotors is to follow the bed in procedure once they are installed.

I used both before Zimmerman is good and cheap. Akebento are good too but hard to find and more expense. I practically used all brake pads and rotors over the 13 years I own the RRS. I would recommend using cermpads.

Use the Powerstop kit. I have them on 3 personal cars (all around) right now and hundreds of customer cars. Not one comeback or complaint. Metallurgy on rotors is good as long as you do a nice break in period and burnish pads to rotors.

Zimmerman rotors and Hawk HPS pads. Rotors are not drilled or slotted. The car stops on a dime and just saved me on the highway yesterday. This was the first modification I did and I'm glad I did it.

Zimmerman makes great rotors.

Had the same dilemma a few weeks back. Went with Zimmermann drilled rotors paired with EBC red. So far I've been pleased with them.

Brakes are doing great.

I just recently did the back brakes at 37k and the fronts last weekend at 39k on my 2020 M340i. Dealer said rotors were at min thickness last June but I waited for the sensors to actually trip and even then I got 1k+ miles with a good bit of pad life left still. Went with Zimmerman rotors and OEM pads from FCP Euro and second that combo. I read too many hit or miss stories about non-OEM pads, I don’t track my car, and brake dust aside like OEM brake feel.

I just bought zimmerman cross-drilled rotors for the fronts. Cross-drilled rotors are lighter but do not dissipate heat better (less material to soak up heat). Stock or slotted rotors are best for soaking up heat.

Zimmerman and Carbotech, EBC do not hold up.
