OS Giken Clutch
Tried this in the 3rd gen forum and got a bunch of views and no comments so I figured Id try it here.
My clutch has been really pissing me off lately. Pretty much it feels like an on/off switch. Getting tired of not lining it up just right and stalling out, looking like a jackass that cant drive stick. So I was doing some research and it seems the OS Giken twin clutch can hold a lot of power but still is really smooth and is pretty close to the stock feel.
Wanted to see how many people here have experience with this clutch and if you feel the same about it.
Also going to the website I imagine that the talk I have seen about this clutch is refering to the STR twin plate clutch not the racing multi-plate. Please correct me if Im wrong.

i've had two twin plates in my 2nd gen and i absolutely love them. they are very harsh for daily driving though, but you get used to it. you can feather them a lil bit but its not like feather a normal clutch but more rather you are jumping a lil bit at a time.

I dont have any personal experience with it, but Ive heard its a good piece...however I know a lot of people with Exedy twin plates, and have never heard a negative comment about them...theres actually one for sale(brand new, carbon? Too lazy to look lol) in the 3rd gen f/s section if you didnt see it.

i have driven four different os twins and they were all quite different. there was one that felt reasonably "stock" ish... one that was brutal on/off and two that were just regular on off like one would expect. for me i wouldnt want a os if your looking for smooth engagement.

I've had the Exedy twin and triple disc as well as the ACT 6puck. Any multi disc setup will engage smother and lighter, but will not slip at all. The ACT will have a much heavier pedal feel, but will slip.

OS definitely has the on/off feel. I got used to mine, but not the best for daily driving. It also uses the pull/push converter which isn't the greatest designed piece..

Thanks everyone for your advice and info. Is the Exedy twin sprung? Im open to suggestions. So far seems like Exedy is the pick of the forum other than ACT and a bunch of people who hate Spec lol.

i finally got the os giken str2c clutch installed and driven it around the past few days...moving from the ACT organic disc to the twin i must say that it wasnt as smooth in engagement but the twin is smoother than the 6 pad clutch in my brothers 1st gen...the pedal is very light i think even lighter than the stock clutch...after driving the organic disc for about 4 years i must say that i am still getting used to the str2c...i dont stall the car or anything but sometimes when i pull off from stop the car will judder when easing off the clutch...but i think i am getting the hang of it...i will keep you updated as the clutch gets more mileage...
also if you do a search on youtube for "twin disc clutch noise" you will find some videos with an nsx, a wrx and an mr2 and you will hear the sound the clutch makes when depressed...when i received my car i must say that the clutch wasnt nearly as noisy as i thought it would have been...it does make a kind of whine when driving and decelerating but i am not bothered by it..

I'm with T2 Vert. If you don't want the on/off feel, definately get a sprung clutch.
I recently installed a Tilton Twin Disc w/ a lightweight flywheel in my FC. It's unsprung, and the feeling is similar to stock, but you can't slip it. You're either spinning tire and going, bucking and going slow, or stalling.
The thing makes a hell of a whistling noise when you're accelerating too, But I think thats the holes in the flywheel.

Thanks for the updates Imamura! Yeah Im deffinetly going with sprung but need to just do some more research and hunting. Thanks for the info everyone.
Was ready to buy though but my wife is "being let go" due to "contractual obligations". AKA some jerk on the east coast that knows nothing about what we do over here decided my wife doesnt do enough for the company. When in fact she is the workhorse of the company and every one is pissed at said individual now. So now is the time of saving and no fun

Cool. Thanks classicauto.
I was emailing A-Spec and they seems to swear by Spec clutches and say that OS are really expensive (which I can see that) and that Exedy clutches are ok but are really noisy and rattle a lot. Cant verify this with out one so does anyone agree with this and have personal experience with this?

Ok I got some feedback on the OS Giken clutch and the Exedy Twin disk. Leaning more torwards the Exedy just because of the price but still thinking. I know a guy that I buy my parts from at wholesale and he was talking about the HKS Light Action single. Mainly because he can get it for pretty cheap and hes a big fan of HKS products. Does anyone use or know someone that uses this clutch?

I have both the OS giken sprung and un sprung. Unsprung unit is in the FB and is very harsh and unforgiving when compared to the sprung unit that is in my FD.
But there is a serious difference between them, the unsprung model is in my FB with a TII tranny & 13BT that sits just shy of 450 PS and it never slips, and has lasted for 4 years of DD with a 8 hour track session 3X per year 15 minutes on, 30 off each time for a total of 24 hours a tthe track each year. The sprung version is in the FD which dynoed at 420 PS and I have had to rebuild it twice. I think that the sprung center encourages you to slip it more making it where out faster.
FWIW everybody wants the OS even though it costs more. the HKS, and Greddy clutchs do not last as long, nor hold as much torque, regardless of the marketing they put out.
cheers
