Zimmerman brake discs authentication

[omaer]

Hello,

I have replaced my front brake discs with Zimmermann rotors, I have just noticed that the sidewall print on the rotors is different from my old rotors, being more dotted than sharp lines, I have attached both,

is there any concern?

Doesn't look as if they're genuine but the best answer will come from the manufacturer.

What was the source for your new "Zimmerman" rotors?

Zimmermann has confirmed it's genuine and they use multiple sidewall marking techniques in the production process.

Thank you for telling us what the answer is... and one in the eye for those of us with suspicious minds.

Translates as "we buy our stuff from whoever is the cheapest and tell them what markings to put on, how they do it is up to them."
