I just used the "syncro-match"

yes but when it matches the revs, its ready to go instead of giving you sensation of throwing you forward in your seat . I am not explaining it well. i just know i think it feels different downshifting coming up to a light with it on or off. If i want to pound around the corner the SRM is awesome. but i usually just leave the car in gear till i get up to the light and then throw it in neutral.

that "sensation" your are describing is a result of you NOT rev matching properly when downshifting, enjoy your clutch while it lasts.

im not really trying to match the revs. You would do the same thing in a large truck to slow it down without overwhelming the brakes. i just go from 4th to 3rd and let the clutch out smoothly, not giving it any gas and it slows the car down smoothly and i dont have to sit there riding the clutch. its called engine braking in driving a big truck. or at least thats what they called it when i got my CDL.

also i have heard (not saying it is true) but if you leave a manual car in gear and let it coast with your foot off the gas the engine does not use any gas. This doesnt seem completely logical but it probably uses slightly less than putting the car in N and coasting up to a stop. Safer to if you need to use power to avoid an accident or something

drove 94k on a stock clutch in a 350z never a problem.
so not sure what you mean about "hope your clutch lasts".......

Ive always engine breaked, and never had any clutch problems.

It's pretty simple, if you are downshifting without rev matching, you are slipping your clutch and causing driveline shock, and yes this will result significant engine braking.

I don't think this is what people mean when they say "engine braking." Typically, engine braking happens whenever you are in gear and not touching the gas. Put it in first and gun it to about 6000 rpm, then let off the gas completely. You will feel the engine braking without downshifting as you described.

See for yourself: Engine braking - Wikipedia, the free encyclopedia

Sorry, couldn't resist.
