Sequential Shifter

Sequential Shifter
Can somebody give me a dummy's explanation of what a sequential shifter does and its value. I've got basic car knowledge but things go over my head quickly. Thanks!

You can do no lift upshifting, as soon as your hand touches the shifter, the computer cuts the gas and you push forward and the car will shift to the next gear. You still need to use the clutch and heel toe for down shifting (by pulling back on the shifter).
GMG and FBL sells conversion kits.

Yes, that's a feature of a sequential gearbox but it isn't because of the sequential mechanism. H-pattern gearboxes (e.g. old MK9s that have been around forever) can no-lift shift. It is having dog rings that enables no-lift shift.

nope. again, due to dog rings, you do not have to use the clutch period. nothing to do with the sequential mechanism.

Note that the conversion kits mentioned here only replicate the shift action and do not provide most of the benefits of an actual sequential gearbox, and they actually complicate the shifter mechanism (some kits can be unreliable). IOW, rice.

in a sequential gearbox you do need to use the clutch in engaging first gear and reverse.
Upshifts can then be clutchless, so can downshifts (requires a lot more skill than clutchless upshifting).
i have a holinger sequential in my viper, speaking from experience

sure, when stopped and engaging any gear you need to use the clutch of course, and again this has nothing to do with the sequential mechanism.

both of the above are your quotes, which one is correct?

"you do not have to use the clutch period" is incorrect. When stopped, you have to use the clutch. I should have said that you do not have to use the clutch when downshifting either.

I have the hollinger-sourced sequential as the stock tranny in my '08 GT3 cup. You should use the clutch when downshifting, and you need to accurately blip the throttle to match revs.
Upshifts ARE fast but not so easy, in the higher gears it's easy to crunch the box if you don't hit it just right. It's cost me about $1K per hour to service my gearbox this year . And that's not unusual.
Here's what is looks like from inside the car:
