Brake discs Zimmermann or Centric

i have zimmermann rotors on the rear and they look like new after one year and no rust unlike others in bought before and since then. Will buy them again. Zimmermann is good quality.

I’ve used Zimmerman for years, including beating them to crap at the track. Never any issues.

I replaced my OEM BMW blank rotors that were done and warped for the blank Zimmermann ones a week ago, but I got them from FCP euro which they had them at a lower price. I have a slow grocery getter 328i so no need to get anything more. I also used Akebono ceramic brake pads.

Zimmerman rotors with ferrodo ds2500's work for me. Also removed the dust shield and added rs3 ducts. Lately been getting about 2 weekends or ~16 sessions before they get low, but they're solid and wear predictably. Plus fcpeuro sells them.

I got ASP pads & fully coated Centric rotors when I did my big brake swap & they treated me well.

What I've discovered is that the design of the OEM rotors are BMW 2-piece brake rotors with iron friction ring with a lightweight aluminum rotor hat. This design , to me, has flaws and is prone to excessive heat and warps rather quickly. I've had the same problem repeatedly. I switched to Zimmerman one-piece cast iron rotors with OEM pads, and I've driven very hard, and it hasn't happened ever again.

I went with Zimmermann discs for their cost and have had no issues with them.

I got 75k miles out of my plain centric rotors with hard track use on my GE

I did Zimmerman/Akebono on my e39 about 3000 mikes ago. My only complaint is the bite. It doesn't have that initial braking force the OEM pads had. It still slows the car down without fail, just a different feel.

front brakes already instaled also i changed brakes fluid for little better one ATE Blue Racing and now it stops better after a while i figure out there is some problems with brakes... i tried to find what is wrong... finally i got it!! brakes callipers was broken... pistons where jammed in callipers... i send it back.. i got cashback and i order another set from diffrent seler unfortunatelly i need to buy another set of brake discs... drilled zimermann set.
