Downshifting to stop? to me it seems like it is just easier to pop into neutral and use the brakes... what are the advantages and disadvantages of downshifting to stop?

the only time my car is in neutral is when the car is stopped for the light or starting the car or crawling in traffic and dont want engine braking, etc.

i usually only downshift to 3rd gear in the Z (down to about 1.5K rpm) to a stop because there's more torque from engine braking in 2nd and sometimes requires more braking to stop the car. if it's a a downhill i will use 2nd.

bascially i like my car in gear at all times while moving so that i have constant control of the car. if im in neutral it will take me a split second before i can get the car moving again. that i dont like.

as a side effect which i dont really care for, you will waste more fuel in neutral to idle the engine than fuel-cut while the engine is spinnin in gear.

Keeping off the clutch and in neutral at a light is bad advice IMO.

Motorcyclists all know that you keep in gear and check your mirrors at a red light. While a car is much larger, I think it's a good idea to practice the same.

If someone is barreling down on you at a red light and you're at the front, you can

a) take a hard left or right along the crosswalk
b) check for cross traffic, dump clutch, GTFO
c) possibly jump the curb (not too likely in a Z)
d) take it right up the ***, which is what you'd do sitting there in neutral anyway

The point is that watching your six and keeping the car in gear means you have options.

Excellent advice -- my original driving instructor (in 1974) taught me this when I was mastering a manual trans in a 1969 Datsun 510.

i used if for about a week after getting the car and turned it off ever since. it's a good feature people who frequently downshift but i don't and if you don't downshift much, the z drives better with it turned off.
