Be sure to check the dimensions of the disc you need before ordering. If the outer diameter of the brake disc is different from the original one, an offset tab (adaptor) will then have to be added. Also remember to put a drop of “threadlock” type glue on the disc screws during assembly. Finally, don't forget to replace your brake pads when changing discs.
