I played with this a bit after reading that guide. It does make a noticeable difference, but you really need to drill yourself to the point of second nature or it is useless and even a little dangerous. There is a lot more time between shifts when you have to push and let of the clutch more often. Does anyone know a trick to lessen the amount of travel in the clutch pedal? If my pedal only left the floor half the distance it does now, that would make take offs and shifting a lot faster. as I would have less area to look for that point where the clutch grips as well as the tires. Using my foot instead of my leg. so on and so forth.
