Which yamalink kit to lower a 2001 WR250F?

Question of the day: "Your kit for the wrf9801, how much does it lower the seat height and is it the connecting rod kit or rocker kit?"

The 98-01 WRF YamaLink is pictured here, and so is the info regarding lowering amount (if sag reset and properly sprung for YamaLink's extra leverage).
