Front Brake Rotor, Zimmermann - E89 Z4 28i/30i/35i

Front coated rotor for the E89 Z4 28i, 30i, 35i (not for 35is).

Purchasing OEM-spec rotors guarantees high-quality castings and high tolerances to reduce warping and vibration while also ensuring an exact fit. These rotors work well with any street, street/track, or dedicated track/race pad sets in our catalog. These rotors typically hold up well to the stresses of track and autocross use very well; we do recommend floating and/or slotted rotors for customers using their cars on track regularly.

Priced per single brake disc. By purchasing one (1) quantity you will receive one (1) FRONT rotor.

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.

Supersedes BMW Part # 34116782601 (34-11-6-782-601)

1-piece rotor. This Zimmermann rotor is a single-piece cast iron rotor. The factory BMW rotor is a 2-piece iron disc with an aluminum hub. BMW advertised the lighter weight as a way of lowering emissions and improving fuel economy. There is likely no performance difference between them but the Zimmermann will be slightly heavier compared to stock. We also offer the Original BMW rotors if you wish to keep the lighter two-piece design.
