A2-104SL - GiroDisc 2-Piece Rotor Assembly, Left

These GiroDisc rear rotors are approx 1,0kg lighter per rotor then the stock units. GiroDisc 3,6kg vs. 4,6kg for the stock units. To allow these wider vented rotors to be installed the OE brackets need to be adjusted; 1.5 mm needs to be removed from the long, inside of the bracket and 3.0 mm from the short, outside of the bracket. When also installing new pads, each pad needs 2mm shaved off.
