High-quality two-piece Girodisc brake rotors for the quality-conscious enthusiast. A direct replacement upgrade for BMW M models, and also a very popular option for many BMW F-series cars when used together with brake caliper adapter kits (for example 380 mm upgrades on M140i / M240i).
Sold as a pair (left + right), price includes 2 rotors.
