I replaced my clutch with a new Luk clutch from Rock Auto. The car is not fully assembled yet. I just installed the transmission and slave cylinder to test the new clutch before I go any further.

The clutch is really soft. I am able to push it to the floor with a pole using one hand as I watch the clave cylinder. The slave cylinder is extending at least 1.5" which it would not do if there was air in the line.

Is this normal for a Luk clutch? I have never had a clutch that soft before. Did I do something wrong on the install? I would rather fix it now than figure it out after everything is back together.

I installed a LUK clutch kit in my Formula (with the 5-spd Getrag). If I remember correctly, I also used a length of wood to push the clutch pedal with my hand as I was standing by the slave. And yes, it was relatively easy to do so. Six years later as a daily-driver (plus dozens of autocross events)... and the LUK clutch is still doing fine.

That is good to hear. I will double check everything in the morning and go forward from there. My fingers will be crossed until I drive it down the road.
