325 x 28mm Two-Piece Floating Brake Rotor

The BMW brake disc, presented by VNE Automotive (and also available as Zimmermann Formula Z), is a high-performance braking component designed for select M3 models. This European spec, 2-piece floating rotor is constructed from aluminum and features a cross-drilled design with a floating hub, measuring 325 x 28 mm. The two-piece floating design significantly reduces unsprung weight, contributing to better handling, and also aids in heat dissipation, helping to maintain braking performance during demanding use. This brake disc is specifically noted as a great replacement part for European spec M3s and a valuable upgrade for US spec M3s that may have originally come with non-drilled or blank rotors. The design incorporates advantages such as excellent deceleration without distortion of the friction ring at high temperatures, substantial weight savings, and radial expansion capabilities under load to prevent shielding and increase resistance to heat cracks. Optimized ventilation channels further prevent "hot spots," and the disc is designed for a 1:1 exchange with original parts, often coming with ABE certification. This rotor is confirmed to fit various BMW M3 models, including Base Convertible and Coupe variants with the 3.2L L6 S54 Gas engine, across model years 2001 through 2006. The product is manufactured in Germany and is an aftermarket quality part, backed by a 2-year/24,000-mile warranty. While it's a direct replacement for many European M3s, it's also positioned as an upgrade for US-spec M3s.
