Lower clutch engaging point after Zspeed CSC replace????

[Hatsuongmai]

I just replaced the stock CSC with the Zspeed CSC last weekend. Did the proper clutch bleed but somehow the clutch engage point seem to be lower after the Zspeed CSC replaced compare to with the OEM CSC. Did anyone in here have their CSC replaced with the Zspeed CSC? Do you have to take out the whole clutch line and replace with the line that came with the Zspeed CSC because the stock clutch line screw on the stock CSC right outside the tranny. However, the Zspeed CSC came with a longer clutch line. Do I have to take out portion of the old clutch line and replace it with the line bundle with the Zspeed CSC? Thanks.
