BMW 428i xDrive Gran Coupe — 2-Piece Floating Rotors Brake Kit
G3500 two-piece floating rotor: an iron friction ring mounted to a separate aluminum hat via floating bobbins. Eliminates thermal warp by letting the ring expand independently, reduces unsprung weight by 20–35%, and handles track-day heat cycles that destroy 1-piece rotors. Available for select vehicles only.
