The primary difference between the 9660 and 9668 is width. Even though the mounting offset on both calipers is the same (making them interchangeable on the same disc), both halves of the 9660 are narrower than those of the 9668. When installed on the same disc as the 9660, the 9668 will sit 11mm further inboard, while also extending 14mm further outward towards the wheel spokes.
