Brake discs Zimmermann or Detroit Axle

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.

Zimmermann rotors are made in Germany, while Brembo rotors are made in Italy....... how would they pull that off?

Zimmerman and Carbotech, EBC do not hold up.
