I just got done ripping out my Spec 4 puck sprung hub. When I got into high boost in 2nd or higher gear (with foot completly off the clutch) It would chatter horribly. There was some hot spot's on the flywheel and PP, but the damn thing never held from day one.
What causes chatter? Is it because Spec sucks? Does the sprung hub cause it? The hot spots?
I dont want to have to deal with it again.
I'm about to order up a clutchnet.com 4 puck spung hub with a yellow pressure plate. Think it can hold 300ftlbs?

 

if it didnt hold from day one first off, it doesnt sound like you broke the clutch in improperly...... that would cause major clutch slippage from glazing the flywheel and disc

 

Lol, I installed my clutch and ripped on it right away hope its ok.. Same with the obx lsd

 

I've heard from a few different sources that puck style dont need a break in, just organic and stock.
But I did run low boost for break in with this clutch, kept it to 12psi for awhile.

 

no need for break in on a pucked clutch they bit from day one. as for it being a spec and sucking from day one your not the first to say that. I have a budy with a accord a20 motor put a spec 6puck in her before he went boost. thing slipped na and was shot with in 25 miles on boost. they suck majorly better off running stocker haha

 

LSD or nothing at all!!!

Chatter is from a serious amount of grip, or in case of a stock clutch - a warped or glazed flywheel/PP. The sprung hub is only supposed to dampen severe shocks to keep from harming the transmission parts.

If I were you, I'd measure how much the pressure plate compresses when bolted up. The clutches I've done in most cars compress by almost the whole length of the bolts that hold it down. It is possible it doesn't have enough pressure on it because of that. The other thing to look for is *any* bit of oil. Thats an easy way to create a slipping clutch. Besides all that, the hotspots are from slipping. Looks like it was slipping quite a bit to me.

It could also be a shitty clutch manufacturer, as they do exist. Action/ACT FTW.

 

did you get the fly wheel machined?
my brake in consisted of me stalling the car 6 times pulling out of the shop :1
