It is constructed as a 1-piece, internally vented rotor with a high-carbon machining for enhanced durability and performance.

Zimmermann utilizes a cast iron material with specific alloy supplements, including copper, molybdenum, titanium, and carbon, meticulously analyzed to match OE disc compositions. This ensures the cast material for each individual Zimmermann brake disc is equivalent to the original parts. The company has extensive experience, over 50 years, in brake disc manufacturing and development, consistently prioritizing product quality and offering reliable delivery from adequate stock levels. This brake rotor is a direct replacement for OE part number 34112227171 and is specifically listed as compatible with the 1995-1999 BMW 3-Series and the 1998-2002 BMW Z3. Zimmermann brake discs are positioned as "spare parts of the same quality" as original equipment, backed by extensive inertia dynamometer and driving tests conducted with TÜV NORD Mobilität GmbH & Co. KG to ensure longevity and prevent issues like deformation and cracking that can plague lesser quality aftermarket parts. Zimmermann warrants its Products against defects in material and workmanship for 2 years from the date of purchase by the Original Purchaser. This warranty, however, does not extend to products subjected to misuse, mishandling, misapplication, neglect, improper maintenance, improper installation, or alterations. As per the Magnuson Moss Warranty Act, vehicle manufacturers cannot void a warranty due to an aftermarket part unless they can prove the part caused the vehicle's failure.
