To me and my friends, rev matching is popping the clutch in and while you're downshifting you tap on the gas and pop the clutch back out. (no brakes used)

Heel Toe is when you're braking and then as you're braking you clutch in and blip the throttle while you're still on the brakes.

But technically, both methods are bascially rev matching the gears when you downshift; so same thing but one method is without the brakes.

You can still jerk the car at any rpm that you shift at. I could even shift at 2500rpm, clutch in but then instantly release the clutch very quickly w/out gasing it and you'll feel the car jerk. I noticied that if i try to shift somewhat quick, sometimes I still gas on back too slow and clutch out too quickly after upshifting, thus feeling the jerkyness. It takes practice, sometimes I can get it right while other times there's a slight jerk.
Same with downshift, if I downshift (without rev matching) but I clutch out way too quickly after downshifting, you'll feel the car jerk for sure. That's what I did when my A4 friend taught me manual, the first time I downshifted from 3rd to 2nd, oh man, I popped the clutch out so quickly that the car jerked so much, heh I think he wanted to kick my butt for that, but from there on I figured how to do it properly :madnoel:

once you can rev-match, heel-toeing isn't much harder. You just have to be able to modulate the brake and gas at the same time with the same foot. Just don't learn this in traffic in case your foot slips off the brake.

Not this soon, I may not even get rid of it, it all depends.

You should get an X-brace from the dealer first anyway.

You can drive smooth on a manual in anyway.

You can make upshifts smooth with out jerking the car and also downshift smoothly even without heel toe/rev match.

Man, heh didn't you sit in Randy's and your cousin's car a lot? I think even riding as passenger you can tell what's smooth and what's not.

It's not like a sin to have some jerky shifts, but it's just more comfortable for everyone else if you can shift as smooth as an auto tranny

I prefer nudgie shifts over reving burn up the clutch shifts. It's like pins and needles in my skull! let off the gas before you change gears dammit!

The best way to get smooth is to watch your passenger's head. Since you are aware of the shift occuring your will subconciously prepare for the shift. You will also notice that smooth shifts are rarely ever quick.

Yeah, I mean sometimes when I shift a little bit quicker and I mess up, you feel the car bouncing a bit b/c I popped the clutch out too quickly but didn't gas it enough.

Off-topic, but how much damage does stalling a car do in general?
Is the lifespan of the clutch decreased by that much more vs. dumping the clutch from dead stops when you want to race someone?

I have no data... but I feel a stall is a lot less damaging than a 3000 RPM race start. I don't think a stall does any real damage unless you are making a left hand turn into oncoming traffic. lol

In my opinion, stalling only really can damage the engine and tranny mounts (from the sudden jerk), which are pretty hard to damage anyway.

Dumping the clutch probably wears it less, but wears other parts (mounts, axles, tires) faster....i dunno.
