Brake discs Zimmermann or Duralast

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.

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've tried 3 brands of rotors just in one year of ownership in my e46. Do Zimmerman. They were my third brand I did. Other 2 warped so damn fast

I like my Zimmerman rotors and akebono pads.

Zimmerman rotors are pretty much the item of choice as far as I know, and I’ve always sworn by Hawk HPS pads if you’re street driving.

I just did my front and rears as well here are the fcp euro part numbers. (No brake dust, & feels amazing)

Zimmermann rotors fits like a glove.

I have the zimmermans, and I've heard numerous people tell me they've seen and heard of them cracking under heavy heated use. It kinda worries me a little, but they've been solid so far, and I've yet to really roast them... Honnestly if I were to do it again, I would probably go with the brembos even though they may be a little more expensive. whats more important to stopping, is pads. The difference between the stopping power and feel of different pads varries greatly. I've had some heavy carbon kevlar pads that took a long while to warm up but once they were warm grabbed really well, but they were kinda hard for regular street driving. I've used stock pads which pretty much suck but last forever, and I've used some softer sport street pads that wear and dust a little more, but stop far supperior to oters for regular street driving. I've yet to push them to the point of fade, but we'll see where that goes once I've got the suspension and bleeding sorted

Tbh drilled Zimmermann Discs are imho Junk. They use OEM Discs. Had so many Problems with Vibrations, warped Discs and so on.
