These Zimmermann Cross-Drilled Floating Front Rotors are a premium, direct-fit replacement for factory 345mm two-piece rotors fitted to the BMW E46 M3 CSL and Competition Package (CS), as well as the BMW Z4 M Coupe and Z4 M Roadster.
Faithfully true to BMW’s original floating rotor design, these rotors feature an aluminium hat for reduced unsprung weight and a cross-drilled steel friction ring for improved cooling. Manufactured in Germany to exacting OE standards, they offer the performance, fitment, and aesthetics expected by enthusiasts and track-day drivers alike.
Zimmermann’s cross-drilled pattern helps reduce brake fade under repeated high-speed braking by venting hot gases and water. Each rotor is precision-balanced and finished with Zimmermann’s coat-Z anti-corrosion treatment to maintain appearance and prevent rust on non-friction surfaces.
Whether you’re restoring your CSL or upgrading your Z4 M’s braking performance, these rotors deliver trusted German quality, authentic construction, and everyday usability in a true motorsport-inspired design.
Please note that for E46 M3 models, these rotors are only suitable for CS and CSL variants.
