I hope i don't sound like a rookie, but since i already have the act clutch, do i need to buy a whole new kit when mine starts to slip? or can i just buy the disk? or maybe upgrade to puck disk? justin

 

if your pressure plate is too worned out, you might have to change the disc and the pressure plate.

but if only your disc is worned, then you could change that.

don't get puck disc.

 

Why shouldn't he get a puck disc? I have one on the way.

 

might be a little to harsh for him..

 

the only reason i said anything about a puck disk is because i heard act is coming out with sprung pucked disk. lets stay on topic people.

 

let me know how it turns out. if it turns out like how I've seen it turn out, i'll say sorry for you now.

 

Ditto .

 

What about all the successful uses for it? I bought it based off a highly experienced recommendation. I think if you know how to use it there won't be a problem. Besides, there will be no hard launches on this clutch.

 

Cody,

I hope not, or you will be replacing your synchros with new ones pretty fast.

 

What do the synchros have to do with launches? Are they not for shifting? Do they help launch you too?

 

There is no connection with a 6 puck damaging a synchro since a synchro is only used to engage a gear, not supporting any power. The 6 puck can however cause damage to the tranny internals , t-case, axles, diffs, etc, if driven harshly. Problem is that its very tough to not drive it harshly since thats its nature.
Answer to the question is that yes you may reuse the pressure plate if there was no problems with it. You will most likely get some chatter though. If you have no problems with swaping out clutches then just bite the bullet and get a whole new clutch kit.

 

The puck adds about 30% more friction and torque capacity, but the tradeoff is a bit of chatter and definitely more potential to break parts. That depends a lot on you though. It's common sense, if you can now transfer 30% more torque and decide to sidestep the clutch at 6000 rpm on slicks... you better know a good towing company! Jeff Hill (Turbotrix) has done really well with it on his Evo, but then again he has been using puck discs on his cars for years and knows how to drive them. You have to know how to drive it so that you are not shocking the transmission. It is not that it is that difficult, but if you assume you can drive it like a street clutch, you may be in for a suprise.
FYI, the spring center will not help in to protect your transmission. Primarilly all it does is help to increase spline life and reduce noise. This is precisely why it has taken so long for us to start producing them. We are still at least a couple months away on that BTW.

 

Well then I guess I will rely on my 10 years of experience racing in the NHRA and IHRA and my 4 years experience racing karts and 10 years experience driving stick (and some cars with puck discs like my 350Z) and venture a guess that I will be ok. Thanks for all the concern!

 

The puck will not be harse for cody, he knows how to drive wand will engauge every gear better then the organic. I told him to get the puck .. and when he puts its in he will see how much better it shifts .. Louder ? yes .. better shifting ? def .. We have been on the same disk all yr.. The clutches work and ACT hands down is the best setup for this car ...

This is not entirely true. Weight of the disk plays a huge roll in synchro life span. Typically a non-sprung puck disk weighs the same or less than the stock organic disk, however, a sprung puck disk can weigh a substantial amount more than the above. This can lead to excelerated synchro wear because the synchros have to work harder to "mesh" the gears when there is more rotating weight on the input shaft.
