Double Clutching Like You Should!

Double-clutch downshifts seem to be the butt of all car related jokes since F&F made the line famous. I have seen a lot of contradictory information across the automotive forums about how double-clutching a synchro-equipped transmission is useless, it’s a technique only for big-rigs, it’s slower then a traditional heel-toe downshift, etc, etc. I double-clutch all my downshifts on synchro-equipped transmissions for two reasons. The first is it is easier on the gearbox. Double-clutching spins up the layshaft to match engine-speed and road-speed, virtually eliminating synchro wear on downshifts. The second is that downshifting is faster because there is no waiting on the sychro while applying pressure to the shift lever while the layshaft comes up to speed. Granted it only takes a fraction of a second for the synchro to do this, but there is zero delay with a properly executed double-clutch downshift. Now, before you start arguing that double-clutching CAN’T be as fast as single clutching because it is so much
