Wow... That is not an easy clutch to drive. Especially shifting out of 1st and into 2nd the transmissions/driveline gets unloaded so quickly that it makes the car shake.



Setup is spec stage 3, spec billet aluminum 8.8 lbs flywheel. Quite interesting. Only have taken it around the block. Hope it will feel better once it gets broken in

i had a 6puck, sprung ceramic/copper clutch, stock flywheel



that bitch does NOT like being slipped, its possible but it fights it hard. I still have it but dunno if its still got meat on it or not cause its hard to tell, unless its just me.



kevin.

i daily drove a act unsprung 4 puck act pressure plate and act flywheel... the hardest is reverse because of how high you have to rev the motor you cant fully get into the reverse gear without hauling ass

i have the act 6-puck ...i've gotten so used to it i can slip it however i need. still bites hard.

the revs drop fast with the aluminum flywheel. What is the thought on life span if you have to slip the 6 puck coppers a lot. Say parallel parking...

hmm... well i know my 4 puck's life span was 9 months, abusing it ALOT and i dont know when it was installed by the previous owner, so it wasnt that bad if you only have to throw a clutch in once every year.. if you really need a 6 puck replacing it once a year isnt bad lol

your crazy.

wtf? replacing a clutch every year? that is not good.

bleh i had to replace my centerforce dual friction clutch like 2 weeks after i put it in, the thing exploded into shrapnel.



i had decent results with the 6 puck one on ebay believe it or not. I just cant tell how much meat is left cause im stupid https://www.nopistons.com/forums/pub...IR#>/smile.png. but i had it on a while, it didnt like being slipped tho it would screech a little bit when ya did it. but boy did that **********er grip.



kevin.

like i said wiener i dont know how long it was in there but if you really need a clutch like that its going to go through some abuse is it not???? well get a clutch in a high hp car and beat the **** out of it constantly and lets see how long it lasts... a year is fine

yea a year is good for beating up a clutch on a high power car.



kevin.

thank you kevin, and like i said again i dont know how long it was in there. but probably awhile

I drove around for a couple months in a 400+ hp mustang with a 6 puck clutch. Talk about a pain in the ass. i spun the tires at almost every takeoff. I was just starting to get it down when I sold the car.

i sure as **** hope i don't have to replace the act, disc that soon, not the most expensive disc but sure as hell not the cheapest either.

nah when i say i was abusing it i was abusing it lol like dropping the clutch constantly, i was beating up that tranny with the intentions of getting a new one hehe and in actuality the clutch fork broke before the clutch itself went out but there wasnt much left on the disc and i wasnt about to drop the tranny again a month later,

A while back I drove a four port N/A BP with a 9 lb flywheel and a 3-puck solid hub disk, and ACT Xtreme pressure plate. That thing was the hardest car I have ever had to drive; nearly impossible for city driving.



Nothing bites like a 3 puck unsprung. You 6-puck guys don;t know how smooth yours is...



I'm still a fan of organic disks for city driving... although I have been experimenting with some kevlar and carbon variations with success.

That's what you think.



The clutch actually isn't all that bad in stop and go traffic. I can't seem to launch it any lower than 1500 without stalling it unless I make the clutch up take super super slow like in parking. But at a redlight where you gotta get going a bit faster 1500 is the best I can do.



The spec clutch stage 3 isn't bad, the pressure plate is not heavy at all, nice and easy to control. It's definitly a bit heavier than stock, but not like the ACT HD pressure plate. Overall I'm very happy with it. I did notice that say you are getting close to an intersection and you need to grab 3rd and you are at 5000 rpm in 2nd and the light goes yellow, you keep the clutch pedal in and step on the brake... The car will stall out. I don't think the BAC can compensate for the revs dropping that fast...

I have a ACT 6 puck clutch & xtreme pressure plate.Took a lil bit to get used to it but I like it alot.It's very chirpy when I race it all the way into 4th.

exedy twindisc is great around town and on the track

^^^^ and on the wallet

I like the copper/ceramic 6-puck sprung XTD setup.

It's bolted to an ACT light steel flywheel.

Plenty of grip (more than the tires).



The pedal feel is surprisingly light for the high clamp force.

Easy on the hydraulics, T/O bearing, and your leg.



In slow traffic starts, I have it fully engaged before 2K, nice & smooth.

thats the one i got, XTD.



i styill gotta tyr to figure out if any meat is left on it, theyre not too badly priced tho so i might just buy an all new kit.



kevin.

If you catch it before it's completely gone, you can often just replace the disc.

im spending over $15-20k easily at the moment on the car, i figure the whole kit wouldnt hurt much more.

I envy your budget.



The light flywheel with the XTD clutch package is a great balance of performance, driveability & fun.



(Now - If I could just hit 3rd more reliably.)

gd has an re amemyia twin disc, its like stock, except its octagonal so it makes lots of noise, you cant hear the exhaust over the clutch

I was running an ACT 6 puck + HD pressure plate .. it was on the car for about 8000kms .. I wasn't very easy on it.. abused it on the strip quite a bit, drove it in daily traffic, did a few clutch drops.. at this point in time I was dynoing at 372rwhp and 302 ft/lb torque.. The clutch never slipped on me...



once we had my motor out at the beinging of the year to rebuild, I found that the clutch had eaten my flywheel and pressure plate apart.. not much disc material left either.. Someone mentioned replacing the act clutch once a year... I can belive it..



I decided to cheap out and try out the ebay XTD clutch.. it was cheap as hell, and since I havn't heard too many reviews on it, I figured what the hell.. if it doesn't hold it, I can replace it and not be out too much money..



The clutch pedal feel is definitly lighter than the act HD plate.. in fact, some might even say it's lighter than the stock plate.. I didn't mind this, since it made driving with the clutch alot easier.. in fact, this clutch doesn't feel much diffrent when compared to a stock system.. .



So how does it hold up? I've now got about 1300km's on both the motor and the clutch.. I had it out for a track day the other day and ran it pretty hard.. needed to see if the motor was going to hold up https://www.nopistons.com/forums/pub...DIR#>/wink.png .. Anyways, the clutch will definitely not hold up to a hard launch.. any sort of hard drag type launch would result in the clutch slipping.. however, runnign on the track, it held up jsut fine... so long as I was easy off the launch, the clutch would never slip, even when powering through the corners and getting on boost hard to redline..



Powerwise, I am probably a bit closer to 400rwhp, and maybe up a slight bit in torque.. i can't confirm this till I get back on the dyno.. however, I'm sure the ACT setup would have been able to handle a hard launch, where the XTD jsut will not..

I think I'll keep running the XTD though, for as long as I can..It just means that I'm going to have to shift my focus from the drags, to the road course for this year...

She's slipping on hard launches? WOW you must be making some serious power or the PP clamp force is too weak. I haven't had much trouble witht he SPEC unit yet. It's definitly very nicely made. I'm still in the break-in process and will update after a track day in august.

So ~400HP is a bit too much for the XTD clutch.

With my ~240HP it holds fine.



I've done a few 5K launches with the clutch feathered.

Then when I release it about 20 ft out, the tires still spin.

I rarely do it, just for a green light drag, to get across the crosswalk paint stripes.

It's not HP that is important. It's torque

Peronally I think the pressure plate is to blame...my old motor made 302ft lbs last year.. The new motor is probably around the same ammount as that.. however, my torque peak is quite high, around 5000+ rpm .. as long as I launch below 5000rpm, the clutch will hold.. however, anythign above that and I'm greeted with the sound of the redline buzzer and the car not moving https://www.nopistons.com/forums/pub...IR#>/smile.png .. once the car is in motion, the clutch holds right through the gears.. only if I try and do 2nd gear 5000rpm clutch drops from a roll (yes.. very abusive) will the clutch slip again...



I'm concidering replacing just the pressure plate with a HD one to give me a bit more clamping force.. however, I'm kind of afraid what that would do with the clutch disc itself.. it's a sprung clutch.. I don't know if I trust the springs from not ripping off the rivets on a hard launch...



Another things to note is tire grip as well.. last year with the ACT 6 puck, I was running 225/50/16's in the rears.. on hankook k103 tires.. they were a good deal, and didn't perform too bad.. I could light up those tires pretty easily..

This year I'm running 245/45/16's in the rear .. Falken GRB's .. these tires have loads more grip than the hankooks ever did.. and I have yet been able to light the tires up due to the slipping clutch... perhaps if I was running the older tire setup, I would see less clutch slip and more tire spin...

Has anyone tried the other clutch on ebay, the blue colored one? In the add it states it's a carbon/metalic clutch which is supposed to be better then the copper/ceramic(safer,more durable- or so their add claims).they are about the same price.

Chris, I don't know what your budget is like but dropping and reinstalling the tranny is pretty high as a $hitty crappy job I don't like doing. So if I was going under there I would make sure I put in the right parts so I don't need to do it for a 3rd time. I got the spec clutch stage 3 which holds 425 ft-lbs of torque. It's not bad, the pressure plate is nice to drive with, just not use to having the disc bite down so hard at the lights. I've got Yoko ES100 245/45/16 tires on the back as well, although I haven't tried to masscre my clutch yet (spec told me to let it break in for 400 miles+), i've only done 300 kms



I would highly recommend the staeg 3 kit from spec, you may want to wait a bit to see if it will hold up to the track when I get the car back there in august. My second recomendation is to go buy racing beat Street strip pressure plate and the Racing beat 6 puck sprung disc. Go buy it from fc3s.org, dave is very very accomedating when it comes to shipping items to Canada and will pretty much help you reduce your taxes across the boarder.





So for today's thought... it is difficult driving the 6 puck clutch with flip flops. That is the last time I will do that.
