Has anyone got information on the driveability of these 3 clutches compared to each other?

Exedy Twin vs OS Giken Twin vs HKS Twin

I am looking at going twin to handle my future upgrade path, but as the car will remain a daily driver I would like the clutch to be liveable! (As well as good for the occasional squirt on the track of course..)

I have tried the search..but if anyone gets a result I didn't please post the link!

I have ORC twin plate on my FD, and my friend had OS twin plate on his supra.

Both car can be driving on street , but OS was easier to drive compare to my ORC

Thanx.....anyone else got some info? I can get the 3 listed above at reasonably close to the same price, So I may as well get the best!

Exedy Twin here. Drove it to work this morning, felt great. Haven't driven any other twin clutch setup though.

PM Jspecracer, he has the OS Giken.

One thing to note about the OS Giken twin plate, is that you must convert your clutch to a push type instead of the stock pull type.

Ive driven an OS giken twinplate on an FC. IT was certainly street driveable...comparable to an ACT 6 puck unsprung disc mated to an ACT EXTREME pressureplate, for those that've driven that setup. Quite a heavy pedal feel with quite a fast bite when you try to slip it.

The thing doesnt lose any weight over stock despite having a light flywheel, due to the additional clutch mass. I wouldn't consider running this unless I were over 450rwhp, personally. There are single discs available that'll hold those power levels easily.

No kidding on the pedal feel of the ACT 6 puck exteme with extreme pressure plate!! It requires an *** load of finesse to not buck the **** out of your car. It does grab awesome for racing, but for street drivability, i no longer like it, lol. If your gonna be in stop and go traffic in this car, this is not the clutch for you.

Keep the info coming guys...has anyone driven more than one type?

(PS car is aiming for some rather nasty horsepower outputs, hence putting the big clutch in now...{Slight overkill for the 100% stock car that it is presently!})

Klar

Hehe, I am too thats why I went twin. But now I'm thinking of "other" methods of large power. I do still plan to use this engine for another aplication though... :flame suit activated:

Are all of the clutch kits complete? I don't see a flywheel on the HKS twin kit. What else do you need to convert it, besides the counter weight? Takakaira has OS Giken and RX7store has the Exedy and are about the same price before shipping.

i had the ACT springless 6-puck on a 9.5# f/w before. now i have the Exedy twin. I find the Exedy less chattery but requires more revs to engage. and the engagement point seems higher than the ACT. the ACT was easier to slip but chatters quite a bit.

if i had to make a choice, i'd say the Exedy is more streetable...also requires less pressure to step on the pedal. haven't tried the otehr brands so I can't say. Isn't the HKS one made by either Exedy or OSG? I know the Mazdaspeed one is made by Exedy.

How much HP can the Giken hold? I just tried the Exedy Heavy Duty clutch and it feels like a statue. I've never driven others, but it was hard not to stall. You guys make the ACT 6-puck seem heavy, I need to try.

I have the newer ORC twin plate clutch kit (ORC 559). Everyone's feedback to me is that it's really hard to drive on the street. I drive it daily and I think I got used to it to a point that it's not an issue. Its really noisy/chattery and the engage point is high and narrow. I've driven other car's with OS twins/triple and Exedy twin carbon... I find those really hard to drive daily in stop and go traffic, especially the carbon.

hope this helps.

I've got the Exedy twin plate... it's very easy to manipulate on the street.

REAmemiya FD3S

do you have the damperless type or the spring type?

GoRacer

Are the kits complete? Is anything else needed to convert from pull to push? Has anyone compare the replacement parts costs?

REAmemiya FD3S

I've heard that the OS Giken twin plate clutch comes with the pull to push conversion. I just bought the ORC Twin Plate damperless clutch which doesn't come with the conversion kit so i'll have to source it from else where.

Here's a very good thread on installing the OS Giken Twin plate clutch along with the pull to push converter:

https://www.rx7club.com/3rd-gen-archives-73/os-giken-twin-plate-adapter-install-330169/

and here's the picture of the pull to push converter:



A counterweight from a Mazda Auto tranny is also required for the install.

RIGHT ON~!!! one question: what do you mean by the clutch point is narrow? sorry for the noob question.

I love my OS Giken Twin-plate setup.

The pedal is rediculously stiff, but I got used to it.

1st gear is tough, honestly, but every other gear is great.

However, combined with my short-shifter, it's actually pretty tough to drive daily. Stiff press + notchy short-shifter = my point. lol

It grabs VERY well, but sometimes it's hard to shift quickly.

Has anyone ever had grinding issues where you would WOT through 1st, then 2nd, cruise in neutral, and then try to put it in 5th? It's happened a few times to me. Air in the lines? If I rev-match, then I'm cool...but this happened in my old T2, except my old T2 had a bad 5th gear synchro, and if I cruised after WOT'ing..it'd actually grind INTO 5th gear. lol

Yeah. OS Giken Twin Plate = awesome setup, but my calf-muscle hurts this week...and you have to really get used to starting out in 1st gear.

hey how about the cusco twin plated clutch? is that just a rebadged exedy?

RICE RACING

Exedy twin plate CARBON clutch with D-Core sprung hub, 100% streetable my girlfriend can drive it !

Takes 750bhp in two rotor form.

Lasts minimum 5 times longer than a conventional metalic clutch.
Can be slipped to ease drive line stress or suit low torque engine to give quick take off.
Best Clutch I have ever used to date.
Rated to 12500rpm.
NO driveline shock due to solid clutch disk = as new transmission and drive line after hard use ........... best compromise for a true road car.
Very very happy with mine, Love it to death.
Done many racing type starts with big clutch slip and track day and about 5000km road driving and clutch has exact same take up point as when installed, virtualy no wear at all thus far.

Back from the dead b/c most twin and triple palte clutch threads have VERY little useful info...

Hey Andy...so what's your impression of the ORC twin plate now that you've had it for a bit? And what's the difference between damperless and spring type? I'm guessing maybe the spring type is easier to engage? Oh and do you get chatter? (I thought chatter was an issue if you don't use their own flywheel?)

I'm not interested in something that I can launch w/...I won't be going to the drag strip w/ my FD. I'm more interested in what can hold lots of torque but is still streetable (ie I can slip the clutch a bit in traffic etc). Pedal effort isn't important...I actually enjoy a heavy pedal

Anyone who has more input on the ORC twin plate, plz chime in. There's lots of info about pretty much all the clutches *except* this one for some reason...

Wow...sounds good. Does anyone else have something positive (or negative) to say about the Exedy twin plate carbon clutch w/ d-core sprung hub? (whew that was a breathful). It seems to be the most highly regarded so far...

Thanks

While I have not used the Carbon Exedy twin or the ORC I do like the feel of Exedy's regular twin, it does allow for "alittle" slippage w/o much chatter.

DaiOni

(twin) carbon vs (twin) standard exedy - would really, really like to know the difference in feel. I'm after something that can cope with 400rwhp and be as streetable as possible (I'm always in traffic).
