What do you recomend for a good hard holding long lasting clutch assym? I don't want to go mild if it sacrifices longevity... I want something that's just plain and simply gonna hold and gonna last. I've got a 1000 dollar McCleod twin disk clutch on my Camaro and that thing should handle anything I give it... My brother needs something similar on the RX7. Right now the car has a full exhaust/intake and HKS S-AFR. We plan to do more... but don't want to do the clutch often. So I want something that can handle what we will give it in the future, and overcome the abuses of daily driving. It's gotta last long and perform well... no messin around here... have I made myself clear!?



Thanks!

I ran the ACT street and had no problems. It lasted me 55k on one set up but the only reason i changed it was that I blem my motor and figured to put a fresh clutch in since the motor was commin out.

I put another ACT street in it. In a street car you will never need anything more than the ACT street. The 6 puck is bad *** and great for drag but rough for street driving and you really will never have a street car that will need it.

How hard is the 6 puck to drive on the street? If it's not real bad that's kind of the one I was leaning towards. My brother is a very aggressive driver and plans to autox the car on a regular basis. So I want something that's going to hold up...

Thanks

The 6 puck is not that hard to drive, but if you go up a lot of hills especially in traffic, then it gets kind of annoying. Its doable for a street car, but in my opinion, i wouldnt do it if i had to go through stop and go traffic every day. The disc last quite a long time, but depending on how hard you drive and how much you slip the clutch, i've seen a pressure plate and flywheel worn to the point that the disc barely engaged because it chewed through the flywheel and pp. But the car was used as a drag car, autox and street car.

I've heard that the puck clutches ARE hard to drive on the street. And I've seen first hand they really tear up the flywheel and PP.

If you've got lots of power and are planning to drag race a lot I'd buy a puck.

Clutches really last a long time if you don't slip them a bunch.

Hmm... so if it wasn't for the 6 puck tearing things up (which is only natural for an aggressive clutch) it'd be my top choice... And knowing the way he drives I think that's the route I'm leaning. We live in a small town in Nebraska. So traffic is next to non, and hills are few and far between. There is an underpass in town though that all new manaul drivers dread But other than that it's way easy driving around here... He just likes to drop it at 7k rpm off the line, and he know's how to slam shift... but for the most part he stays away from doing that for now until we strengthen the tranny...

Thanks

how about an os giken twin plate clutch, or one from hks?? They should have plenty of holding power:

Go to www.takakaira.com, but i'll warn you... lotsa $$$

agent712

Umm.. twin disk? Ahh, I think that's probably a little more than we need. Maybe someday when we're running 10's... but for now I just want a heavy duty single disk...

V8KILLR- Is that your final answer? Sheesh... ACT only has a half a dozen to choose from bro :P

Racing Beat also has a heavy duty setup. They don't advertize it in their catalog, but the pressure plate is a Mazda factory competition PP and the HD disc is a Ferodo. The disc has no marcel springs, only the center hub springs, so it is either engaged or disengaged- there is no in between, so driving in stop and go traffic takes some additional attention so you don't either stall or constantly spin the tires. Slipping the clutch to hold on a hill produces enormous volumes of burning clutch stink. But- it really hooks up when you want it to. Don't know about the longevity yet. I have only about 30 K miles on it. So far, so good.

agent712

You have 30k on a clutch? Sheesh.... He's just about burnt up a stock clutch within a matter of 2 months. And I only got 3k miles on a Centerforce in my Camaro before it wasn't holding like it should... lol

The HKS multi plate clutch is not streetable. My roomate put the triple plate in his 600+ rwhp Supra....and well. Let's just say there was an ACT in it the next week.

I'm not saying that all multi plates are like that...but the HKS one is pretty much an on/off switch.

HKS does have the GD Max spung hub clutches that are alot more street friendly but for the $$ I would suggest ACT...hey it's proven to work on both street and track cars what more can you ask.

spoolin

you guys in nebraska are doin' somethin wrong

RotaryKnight

Get the ACT street/stip clutch simple as that.

If you have a Camaro you may have heard of a clutch company called SPEC. Check them out. Outstanding stuff. BNR Supercars sells them. They also help sponsor this forum. Check them out. You'd want the stage 4.

Centerforce isn't all it's cracked up to be.

RotaryKnight

Good for stock replacement but not if you are running decent HP.

jspecracer7

Good go for the OS Giken Super Single. Streetable and will hold appx. 400 ft./lbs of torque.

is this true, i just baught a centerforce dual friction today for $540 and you guys say it sucks ***! how bad is it?

blackscorpio

Id go with the ACT street Strip, Its pretty quick grapping and not too harsh to be streetable.

agent712

Spec, ACT Street/Strip, or ACT 6 puck, or OS Giken Super Single... cast your votes now
twstd rx- Yes, I've heard of spec... didn't know they did RX7 stuff. I'll have to look into that. Thanks
KINETIK_FD3S- Sorry bud, but I personally have vowed to never buy a Centerforce clutch again. They are right... they're just not all they're cracked up to be. Although I was making about 360 rwhp with mine, I still think it should've lasted longer than it did. Hopefully you'll have better luck than I did... But if you can I'd consider sending it back and exchanging it for an ACT....
RotaryKnight - Yeah yeah, I think you're leaning me towards the Street/Strip now. If you say it holds then I'm going to trust you. How is the pressure plate compared to stock?
BTW. another reason I want something better this time is because my brother could only chirp third gear for a couple weeks with the stock clutch... now the car won't even chirp second I want something that's going to hold up here! I'm leaning towards the above mentioned 4... Not familiar with the OS clutch at all... anyone have a link and more details on it compared to an ACT?



Thanks
Chuck

agent712

How about the ACT Heavy Duty 6 puck? It's only 40% stiffer than stock compared to 59% of the Xtreme... I think I'm leaning towards the heavy duty 6 puck... 40% is just about right, and it holds a ton of torque. I find it very strange that their clutch's are all so close in pricing btw...

Honestly ACT uses a stock disk for their street/strip set up but a "buffer" pressure plate. Kit comes with dick, plate, t/o bearing and tool.

Giken is a great clutch but just think the ACT would be a better bang for the buck.

I've just had alot of good ezperiences on ACT with the 3 cars that I've owned and with friend's experiences.

agent712

So then an ACT 6 puck? Heavy Duty or Xtreme? I think that's what we're going to go with unless someone tells us otherwise. Main concern is driveability... and from the sounds of it we should be fine in that department. Obviously it's an aggressive clutch, but nobody has said it's not tolerable on the street...

Thanks

The 6-puck is a poor clutch for anything but a road course IMHO. Launching a 6puck in daily driving or on track is devastating on the drivetrain and in the 7 the drivetrain is a weak link. These simply shutter like hell at launch unless you grossly slip them, then they heat up and other bad things happen (heat checking, sticking, grabbing).

The ACT street/strip with an extreme PP is a nice middle ground as the disk will slip enough to cushion the driveline shock, it handles massive abuse, and holds mucho torque. I and several others have gravitated to the ACT after trying the 6-puck and the Centerforce CFDF. Working well for street, strip, and road course.

The Centerforce is a great stock replacement that will hold near 400 RWHP, but, it won't handle aggressive launches or shifts. Several of us have smoked these with aggressive launches (clutch dumps) on street tires no less!
