hey everyone! since there are so many brands and types of clutches out there, id like to get a discussion going about peoples expieriences using the various clutches. id also like to compile a good list of the diffrent clutches available.... i can add more to the pole as people mention them.

Also help me list the different TYPES of clutches as there are so many.... i can think of off the top of my head

4 puck
6 puck
twin plate
tripple plate
pull type
push type
etc..................

Please tell me any other clutches you think of and i can add them.


hopefully we can first list the options that are out there and then discuss and compare them in regards to diffrent needs people have (street, strip, high HP, etc.)

im trying to bring all of this clutch info together in one thread. there are other clutches that were not discussed in that thread... basically im trying to have everyone pull all the info out there together into one thread. i feel that something like this will make it easier for people (especially newbs) to see what ALL of their options are. i know the search function is handy, but i would be nice to have all the info on one page... im not trying to double post........

check out some of the other forums, like the miata one for instance.... there is an effort to make things SIMPLE and concise for readers. -heath

Don't ever buy anything from pettit !!!! Especially something as vital as a clutch flywheel and pressureplate...

user 9348703

OS does it all.

yup.

that ACT clutch u have on your car is made by OS

jspecracer7

That's the biggest load of crap I've ever heard. Unless ACT makes a PUSH type clutch for FD since the OS single plate clutch is a PUSH type while the ACT is a PULL type.

if u ever look at a ACT pressure plate u will see the OS Giken stamp grinded off.

ive heard nothing but good things about ATC. i plan on getting the atc ss when im no longer poor...

user 9348703

Hummm never heard that before.

OS has kind of its own look. Its not the prettiest clutch I have ever seen, but so far its the best in my book.

Exedy sucks--Never played with the carbon one though

HKS Hyper Single--- on FEEDs Spirit R when I went for a drive gripped very nice, granted they had a 2 way Kaaz in there too, but no problem to grip and throw us sideways with not too much power FUN!

ACT Does make a push style

I have the ACT 4 puck street and strip. The only thing that I have found bad with it is you cant really slip it at low rpms. ie in a parking lot. All in all Ive had no problems with the clutch.
Its about 30% stiffer for clutch pedal feel.

I have run it at the track many times and on the freeway high speed rolls. No problems at all.

Ditto. It's great, holds well, I haven't had any problems with it. But the engagement is NOW. No slipping allowed, it's either in or it's out.

mad_7tist

how about the bonez stuff from rx7.com?

Liar ! I said that in a previous thread and you called BS on me, I just couldn't prove it, so I didn't precist

Has any body used the Exedy 3 puck clutch or any other 3 puck what do you think.

Cusco makes clutches for our cars...so does FEED.

FD's use a pull Type clutch and FC's use a push style, most manufactures make both because they have to. Just like the MKIV Supra's use a pull type also, that is why Centerforce clutches suck for the FD's and Supras, because Centerforce usually uses weights on their pressure plates with cintrifugal force to clamp hard. On pull type clutches the weights would fight the grip of the pressure plate instead of help it, that is why they don't make them with the weights, and never by a centerforce for an FD because I've had them slip on mildly modded cars.

Anyway, I use RPS MAX series and ACT 6 Puck and they seem to be working very well, I've pulled a 1.6 60 foot with the RPS and a 1.7 with the ACT, and the RPS has a sprung and is more street friendly.

hmmm good info here so far! ok i have a few questions...

1) it seems that we are all in favor of pull type... anyone disagree and if so why?

2) can anyone who has driven both compare a 6 puck, and a 4 puck (i suppose ACT is the most popular)

3) in regards to OS Giken... would anyone like to talk about the 2 plate, and 3 plate (i think they make those) clutches? advantages/disadvantages? do multiple plate clutches allow more or less slip than say one of the ACT street stip clutches? (im assuming that MOST readers need something that is able to be used on the street/highway) also the 2/3 plate clutches must weigh more and add to rotating mass correct or no?


thanks for all the great responses so far.... keep em comin -heath

PS should i add anything to the poll?

Villision_Motorsports

Ty yes they do that is why my ACT is a push style on my FC and Tim has the SIX PUCK ACT on his FD and it is a Pull but one thing we had a problem with in the past is the ring that is inside the pressure plate the clips onto the throw out bearing was to small for the pressure plate so we had to use the stock one we took off the first time so make sure all your parts work before you start tearing into things guys.

Has anyone experienced a collapsed/weakened diaphragm on the ACT extreme pressure plate.

boostin13b

You can't really be in favor of either. Either you have a FD or an FC, like I said, you have to go with a pull type if you own and FD, unless you want to swap to a FC tranny, and vise versa. I haven't really heard of any advantages of either, unless your going to go with a Carbon Carbon from like RPS, because I think they only make the Carbon Carbon for the pull type clutches, but I may be mistaken. I've installed plenty on supra's and haven't found a better clutch, but they are pricy, they help with not breaking your transmission also because they slip a little when they are cold like it would be in first gear so you won't have that huge shock to the tranny, then when they get hotter they grip better. I should check to see if they have made one for the FD yet, last time I checked they didn't, but it's been a while.

I dont have any experience with the 6 puck ACT but was told and read that the clamping pressure is in creased and will hold more HP and more torque. Plus it is supposed to disapate heat better just because it has more surface area. I didnt go with the 6 puck because I wasnt going to be putting out huge numbers and I says its not for street use. I guess that they would know better than me so I took the 4 puck

Here is some info on the 4 puck

The ACT clutches are one of the most popular choices for the RX-7. The Racing 4-Puck
version (ZX3-HDR4) clutch has an upgraded HD Street Disk with Heavy Duty Pressure Plate over the factory clutch. The HD improved disk and pressure plate provides a new torque capacity of up to to 514 ftlbs, and the pressure increase being 40%.

oh, also i was looking on the rx7store website and they didnt mention the difference between the 4puck regular, and extreem..... it looks like all their pressure/holding specs are the same, just the price is different.

personally i am on a quest for a clutch that i can use on the street or in traffic if the need arrises... but im also going 20b, so holding capacity will come in to play if i swap the ecu to an aftermarket one.... but it wont matter when i first get it going. im trying to find a nice balance between drivability and holding capacity.

jt-imports... can you tell me more about your expieriences w/ the OS twin/tripple plate clutches? whats the advantage over say an ACT 4 puck?

Edit: I just did a search for the OS twin plate clutch.... one website wanted $1800!!!! if this is the going price then OS is out!
