Although there are plenty of folks that have lowered the C14, the one thing that comes into effect on it, that would not be an issue on, say..a ZX14, is the shaft drive. Introducing angles into the U-Joints that possibly take them out of alignment, could cause premature wear and vibration. Like I said, plenty of folks have done it, and probably not had any issues, but that is most likely why a suspension expert hasn't commented, or returned Your queries.
