step one: pull up ebrake holding the button in so the ebrake does not lock on you.. Pull the ebrake up as far as you can..
step two: bring the clutch out till it BARELY starts to grab, too much and you will burn you clutch up.
step three: hit the 2step by going full throttle ( if you do not have 2step (launch control) then just find a good launch point, in my teg i usually launch about 3.5k)
step four: release the ebrake
step five: release the clutch out completely the second you feel your car move.
Now, if you trying to do this on a single disc clutch, it won't work as well. You will burn the clutch up quicker. This pre-load method is more towards cars with twin or triple plate clutches
