Weight savings are on the video, I weighed fully assembled, no tire. Front dropped from 7.1 to 7, due to the full floating rotors weigh more, but weight will be closer to the centre. Rear dropped 3.6kg. 9.1 to 5.5kg. The turn in is completely different. Had chance to take it out once on the twisties and its really night and day. See on track with full floating rotors the improvement.
