The EBC Racing 380mm front left floating disc ring replaces the outer ring on fully-floating two-piece SD rotors. Specified for vented floating rotors, it uses 48 curved vanes, a swept-grooved finish and a 380mm diameter with 36/34mm new/min thickness. Install it as a direct replacement to renew rotor surface and maintain correct cooling vane performance on the two-piece rotor.
