Front Brake Rotor (Vented), Zimmermann - E21 323i (and 1977 320i)

This Zimmermann Z-Coat rotor fits the FRONT of E21 323i. It also fits 1977 E21 320i models that originally came with vented front rotors.

Zimmermann Z-Coat rotors are the same size as stock BMW rotors but include an anti-corrosion phosphate coating that resists rust. Uncoated aftermarket or OEM rotors will quickly rust on the middle hat and inner vanes. Zimmermann Coated rotors are made in Germany and can be found as original equipment on some Mercedes, Porsche, and Volkswagen models.
