GiroDisc Rotor Assembly Rear Left – BMW 2-Series G87 & more (A2-322SL)

GiroDisc 2-piece rotor assembly, rear left (part no. A2-322SL) for BMW 2-Series G87, BMW 3-Series G80, BMW 3-Series G81, BMW 4-Series G83 and more (see Fitment).

The GiroDisc 2-piece rotor system is a direct replacement for the OE rotor, no modifications are necessary. The disc will bolt directly to the car and work with OE calipers perfectly. Once the Girodisc system is in place, simply replace the cast iron rotor ring when needed. The average Girodisc 2-piece rotor is approx 2kg lighter per rotor then the stock units. This reduction in rotational and unsprung weight allows for quicker acceleration and suspension response.

Key Features

Notes:

• These GiroDisc rear rotors are a direct replacement for the OE disc however the factory iron pad shape must be used with the carbon ceramic calipers. This is done to keep the rotor weight at a reasonable level while offering a broader range of aftermarket pad options.
