GIRODISC A2-012 Rear Brake Rotor Kit for BMW M3 (E46) / M5 (E34 / E39)

Description GIRODISC A2-012 Rear Brake Rotor Kit for BMW M3 (E46) / M5 (E34 / E39)

The GIRODISC A2-012 rear brake rotor kit is engineered as a direct OEM replacement for BMW M3 (E46) and M5 (E34 / E39) platforms, requiring no modifications for installation. The 2-piece floating rotor design bolts directly to factory calipers, simplifying maintenance and replacement procedures. Once installed, only the cast iron rotor rings need to be replaced when worn. This performance upgrade delivers an approximate 2 kg reduction in unsprung and rotational mass per rotor, improving acceleration and suspension responsiveness under dynamic driving conditions.

• Direct bolt-on fitment with OEM caliper compatibility
• 2-piece floating design enhances thermal management and serviceability
• Weight reduction improves unsprung mass and vehicle dynamics
• Curved slotted surface for consistent pad contact and heat dissipation
