Hey guys, i was going to buy a clutch and came across this situation, 6-puck sprung or 6-puck solid hub, what do these mean/purpose??

The springs in the sprung disk will help minimize the initial impact of the clutch engaging into the FW/PP and is recommended for DD'ing. Unsprung, unless you like the "on/off switch feel", is more for race applications...but people all drive differently and has different likes and dislikes of how they want their car to drive and feel.

would the solid hub grip or grab better?? like for example if im trying to pop the clutch to scratch 3rd gear or something

to scratch third gear. lol. sorry.

i had a 6 puck sprung and loved it. just got a 4 puck unsprung from a friend for the low low woth lots of life and its def. different.

im sure that they both are gonna grab the same.

the unsprung clutch grabs more,

so the solid hub will chatter alot or a little when pulling out from a complete stop????

OMGWTFBBQ!

If you don't rev match correctly on a solid hub, the clutch has a wonderful tendency to bounce its way around the flywheel, which shakes the car quite a bit more violently than you would expect that little piece of metal to do.

I have destroyed enough Type R trannies to tell you the honest to God's truth:

DO NOT GET A PUCK STYLE CLUTCH DISC FOR STREET DRIVING!!!

You can ignore my advice and try to be Billy Streetracer and you'll end up buying a new tranny like I did three times before I grew a brain and went with a full face organic disc which has now lasted me three years with zero tranny problems.

Puck style discs also wear a huge groove into the flywheel for street driving as well.

Also if you are going to be stubborn and get a puck style clutch, do NOT get a sprung hub type puck disc.

"But why?!"

Well because believe it or not the sprung hub puck discs ratchet far worse than solid hub puck discs, and they actually tranfer much more shock/load into the diff and final drive, thus breaking them - I broke three myself.

You might also notice that one of the best clutch makers, ACT, doesn't even offer a sprung hub puck style disc (or they used to not) because of the very ratcheting/breaking trannies I'm referring to.

BTW:

I'll be glad to post carnage pics from some of my destroyed ITR trannies from my 6 puck sprung hub ClutchNet disc, but for now a few pics that I've found so far:

ITR tranny with broken final drive due to puck clutch:



Here's the replacement fullfaced disc after I got smart - test fitting to make sure splines match:



Brand new ITR tranny:



Opened box:



I mean unless you enjoy tearing trannies up by all means get yourelf the baddest, stiffest, racyest puck clutch possible.

...just be sure to also buy a Helm's manual, http://www.helminc.com and memeorize the transmission R&R procedure.

Oh yeah since we're talking clutches let me also show you guys what too stiff of a pressure plate can cause too:



I had to drive 60 miles home from the dragstrip because of a broken clutch fork.

I have broken 2 of them, so my third is my current, unbreakable welded/gusseted version:





Learn from my mistakes - don't get the craziest clutch you can buy just to say "I've got a stage 11 clutch y0!"

Stick with the Exedy Stage one, or ACT Street plate/disc combo.

what about the exedy full face organic O.E clutch, does that clutch hold good for street driving and for having a little fun scratcing gears too????
