@80MOOSE08 if you downshift regularly without double clutching, your trannies synchros have to do all the work and you'll see your RPM's going up from shifting down. by double clutching, you rev to approx. where your RPM's will be in the lower gear youre going to and your synchros do little work and you wont get that jerking after downshifting and it will shift 10x smoother if you do it properly. i do it clutch in, neutral, clutch out, blip the throttle, clutch in and shift down

i like to drive like this on the way to classes and around town, i have an 04 tacoma and its not meant to do what i do so well with it. it only revs high enough that i can go through two gears close together in time. if i didnt double clutch, my mechanic would be asking for a kind of money that i just dont have at this point in life. i can afford a throwout bearing, but not a new set of syncros.

That's heel-toe double clutching rev-match downshift. The propose of this is to match rotational speed between engine-tranny and tranny-wheel before move shift lever to lower gear. Apply double clutching rev-match with heel-toe for downshift while braking and approaching to corner is perfectly match that reduce clutch disk and syncro ring worn out. Compare to normal rev-match it's a bit complicate. Normal rev-match depress clutch only one for downshift while the other depress twice.

Is this a form of engine breaking as well.

And what's the point of it? Can someone explain to me, I've seen it being done in rally cars it looks badass.
