When the cluch disengages, it moves back from the flywheel on those splines. The splines on the T5 input shaft are not long enough and have to be legthened. I am finishing up a T5 install, but used a spacer to avoid modifying the transmission so I can't give you measurements.
I guess I should ask, do you have full cluch pedal travel?
Do a search, there is lots of information on the lengthening of the splines. Good luck.
