There are substitutions available for Audi Wave brake discs: first supplier for the aftermarket is Zimmermann.
Zimmermann offers an alternative to the Audi Wave disc in its brake disc range. The original disc is characterized by "waves" on the outer diameter. The Zimmermann disc is, just like the original disc, a composite disc made of aluminum hub and a casted friction ring.
The technical advantages of the compound disc, such as weight savings and free radial expansion of the friction ring due to the floating mounting, are provided by the Zimmermann brake disc as well as the original brake disc.
The machining of the braking surface is executed with holes like the original disc.
The Zimmermann brake disc has no waveform on the outer diameter due to a patent protection.
