Description
Upgrade your BMW's braking performance with the GiroDisc 2-Piece 400mm Slotted Front Rotor Kit. Designed as a direct replacement for the factory front brake rotors, this premium two-piece rotor system bolts directly to the vehicle without requiring any modifications while working perfectly with the original OEM brake calipers.
The GiroDisc two-piece design significantly reduces rotational and unsprung weight by approximately 2 kg (4.4 lbs) per rotor compared to the factory brake rotors. This weight reduction helps improve acceleration, steering precision, suspension response, and overall vehicle dynamics while maintaining outstanding braking performance for both spirited street driving and track use.
Unlike conventional one-piece rotors, the GiroDisc system allows you to replace only the cast iron rotor ring when it wears out, helping reduce long-term maintenance costs while preserving the lightweight aluminum hat.
Precision-machined and engineered for durability, the slotted rotor design improves pad bite, helps evacuate brake dust and gases, and provides consistent braking performance under demanding conditions.
