yeah thats how it would seem but everytime ive driven a car that had a unsprung puck style it felt smoother to me... they were all awd also though... idk from what i gathered its more of the sprung clutch chatters more because of the springs compressing and expanding without the clutch being able to slip whereas the unsprung may take off harder but it doesnt vibrate as much... idk its not that detrimental like i said its only for a little while i'll probably put like 4-500 miles on it before i get a full new clutch setup (clutchmasters stage 3 full face kevlar) ive seen them hold 700hp+ with no issues and there VERY street friendly almost like a stock clutch just heavier..
this is what ACT states on their page:
6-Puck Sprung Hub Race Disc (G6)

  • Recommended for Road Racing or High Powered Street
  • Increased Torque Capacity and Spline Life
  • Very Good Durability
  • Quiet Operation, Reduced Driveline Shock
  • Harsh Engagement and Chatter
6-Puck Solid Hub Race Disc (R6)

  • Recommended for Drag and Road Racing – Not For Street
  • Increased Torque Capacity
  • Faster Shifts, Reduced Inertia
  • Very Good Durability but Shortened Spline Life
  • Good Heat Absorption
  • Harsh Engagement, Some Chatter

On their website they list every one of their clutches as having harsh engagement or worse. Just Google peoples experiences with "sprung versus unsprung" (takes about three seconds to figure out which is the harsher ride and least popular for a regular street car). I can only assume that you're either talking to people who don't know what's in their car to begin with, have soft pressure plates (in which case a sprung plate would probably feel rather mushy) or gutless power plants. I'm not guessing; I've driven many of both and in several cases tried both in the same vehicles... unsprung are harsher and if the whole assembly has a lot of grab may make a car miserably jumpy. In the end the overall feel comes down to the complete assembly (flywheel, pad configuration, contact surface area, pressure plate and clamping force) but no matter how streetable either one may be the unsprung clutch plate is the harsher engaging and transfers more shock to the drivetrain than any identical unit which is sprung.

I'm not really posting this for your benefit anymore. You've chosen what you want and it may or may not work out well for you and your setup. I'm posting this for future readers.

Don't forget to get the flywheel resurfaced.

yeah i get what your saying and its the same here ive driven alot of cars with lots of different clutches being what i do for a living, but i also know the unsprung was in stock and the sprung was on 2 week back order. it cant be any worse than driving a twin disc dd which ive also done the harsh engagement isnt really an issue you lear to feather the throttle as well as where the clutch will allow a little slip etc etc. it shouldn't be too bad with the stage 2 pp the stage 3 kit with 6 puck sprung has a little heavier of a pp and the stage 4 6puck unsprung also has the plate (getting tired of the "stage" nomenclature) i guess i'll know how bad it is tomorrow and report back with some info.

just fyi for everyone reading... the clutch engages "solidly" but by no means "harsh" unless you just drop the pedal (as any other clutch would) it slips just as my full face did on take-off and i get absolutely no chatter in 1st gear and very little on a 2nd gear takeoff overall very happy with it and it seems plenty street friendly just dont clutch kick all over the place. plus a big positive there is NO break-in period so you can drop it in and drive it as you normally would right away its even a little quieter than my full face while in drive throughs i could always hear my old clutch while idling up to the window just got back from mcdonalds and didnt hear anything from it at all
