Hello Folks,

yes I was reading via search, but didnīt find exactly what I was asking for.

I got a good offer for an OS Giken Super Single Clutch Set for my 98ī DC2R incl. lightend flywheel, throwout bearing....

No, I read that it was
a) loud (rattle sound when engaged?)
b) very heavy (pedalpressure??)


It would just pay about 180$ for the complete set with less than 12k miles on it.
My first clutch was OEM, a spring broke @ 70000km ... then I bought a F1Racing Clutch Stage 2 (Stock Flywheel) where is now also a problem @ 105000km...

The stage 2 is no problem to drive allday, its not noisy, the power to push pedal down is heavier than OEM, but even my wife is driving my R allday to the shop or to work (80km each)...

My R is completely stock (engine, catbkac, transmission), except an K&N replacement filter, modded OEM Airbox and the Stage 2 F1R clutch...

I once heard a 2 plate clutch on my buddys Evo8.. which seems not so bad with that rattle. This is a metal clutch (stage 2).. and he can drive it also allday, the pedal is a bit heavier but not unpressable.


So now Iīm asking:

How is it driveable with the OS Giken realy?!?

Will there be bucking when driving easy with 1200-1500 rpm from the traffic lights in the cities?
How is the friction zone (is this the right word?) when driving it smoothly?

Is there any need to replace the parts or do they last a live long?

Thanks for helpful replies and opinions


regards and greetings from germany,

Christian


Edit: YES, I KNOW that a Exedy Stage 1 would be enough for me... but itīs a good offer for me cuz I get a lightend flywheel, a clutch with bearing from a very good manufacteur for a good price...


here are some pics added:











is it organic or metal? what do you think?

 

I currently run an OS Giken SS setup in my Spoon 1.8L stroked B16B. It rattles very loudly and it has massive pedal pressure. It is not even close to being able to be streetable. Stop and go traffic will destroy it and you'll be left with a slipping piece of crap that needs to be rebuilt. If you plan to only road course or drag race the car then go for it. If you plan to daily it don't bother. It's a pain in the dick.
Edit:
To directly respond to your question: The "friction" zone is "on or off". The pedal pressure is VERY heavy. Low rpm driving works once you get used to it. You'll buck alot at first. The OS Giken (you have a Cusco clutch kit pictured) kit is amazingly resilient and I'd recommend it to anyone with a racecar.

 

I have had great luck with ClutchMasters clutchs, I have had a Stage 4 holding 600whp+ ( With street tires) and it's still very lilght pedal and smooth engagement.
We install lots of CM stage 3s and there like stock.

 

I also have an OS Giken Super Single and its a very nice clutch... but its in my weekend car. Not very traffic friendly... and yes it rattles a lot. I've had so many people ask what the hell is that noise everywhere i go.. its very annoying.

The clutch itself is wonderful and yes, it will take a while to get the hang of low speed driving. No issues at all, but the rebuild kit goes for $400+ range... very expensive but it does come with a new pressure plate, bolts and clutch disk.

here's a pic of mine

 

CM Stage 3? I have a jrsc'd itr, and i was thinking of getting the fx200 (stage 2), should i get the stage 3 instead? sorry to thread jack, but im in the market for a new clutch too

 

Yes, it says cusco on the cover, cuz cusco buy them, respray them and sell them as cusco afaik!?

Mhh, well. Thatīs what I read already... but so, it just should be the truth. Mhh, it was just a got offer for that low of money to get something HIGH-END like this :/

The rattle is no problem, people just stare and look at my car already (ITRs are VERY rare here, its white, red wheels, its got a wing on the back and its pretty low -.-) .. so, i dont care about them.

But ok, I dont wont to brake it with daily driving and get the rebuild set für 400$+ ...


Thanks guys for this preventation.

If anyone is interessted in this set for 150 British Pound, I will forward the connections details...

II I just got the fx100, i was thinking about the fx200 but the buget did`nt permit..let me know how you like your setup!!!!

 

I have OS Giken, and had the Cusco previous to that (both super singles). The pedal pressure isn't too bad; you'll get use to it in about a week or less. The rattling happens when the clutch is disengages (clutched in), but again, you'll get use it. I personally think it sounds cool now.

Performance-wise, they grab pretty well. I road race and so far I have never experienced clutch slippage, so it all works well. There is an option to get the 215mm disc which handles high RPM and torque better. If you have the funds, I would opt for that.

And I wouldn't describe it as completely unstreetable, although it will take some getting use to...

 

Good info!

 

OS Giken makes the clutch FOR Cusco. The pressure plate cover is machined, not stamped like the OS version.

I had this setup; a bit extreme for stop/go traffic but i loved it. The flywheel is very high quality, better machining work than the Toda IMO

 

This looks now also different from what has been said some posts earlier.
I donīt care about the rattle cuz I dont care about the people who care about my R




Sure, the flywheel looks great.. its a very high quality set, i know this. But Iīm driving about 20-25k km in every driving-season (april to october) and just on ly 2-3 trackdays.

But the price is very charming, thats why Iīm so confused what to do.

I had a stage 2 clutch with light fidanza fw in my EJ6... and it made the care realy annoying to drive, i hated it realy.. because the clutch - even gently managed to prevent it from bucking - had a silly friction zone and had that bucking always in the first two gears...



I realy dont know that to do know.. should i go for it or not.

I got also some other offers. Clutchnet Stage 2 with Fidanza, but for 3 times the price of the OS Giken ... :-?

edit: Mhh, yes, before I forget, its the 204mm one afaik..

 

I got sick of the rattle real quick too.... People kept thinking i was losing a bearing or something lol

 

As I said, I dont care about the rattle ... the people around should wonder and Iīll let them DIE stupid

So now... should I go now for it or leave it?

 

A friend of mine had one of those on his B16B swapped coupe...it definitely took time to get used to driving in traffic. As said before, it is either on, completely, or off. His rattled like hell...as mentioned above you will have people asking what the hell is wrong with your car. The clutch will take a ridiculous amount of abuse though, and it grabs like hell. The clutch/FW package are also very very light.

 

Mhh, thats what I like... a high quality product in combo.. a light flywheel, light clutch and a durable bearing.... the rattle is the tiniest problem ...

As it turns out, the clutch is realy racey. Sure I get used to it, but I want a slightly smooth pedal to drive in the city... If it knows just ON or OFF, it will be bucking and have to drive with 3500rpm of the line :/


Hrrrrrrrrrrrrrr... man.... itīs difficult to decide

 

I disagree with some opinions here.

I have the OS giken super single clutch assy. on my teg. B18b turbo, aroud 260 whp..

OK, It rattles a bit when clutch disengaged, people think that the release bearing is worn out, but when engaged the rattle disappears totally.

the pedal is not so hard to press, I drive in traffic everyday with it and I got used to it the first week...

something is true: its an ON/OFF clutch... but you'll get the trick!!

Im driving it since 2 months and it NEVER slipped, even after minutes on the track...

its a VERY nice clutch IMO !!! for both track and road use!

 

I disagree with the OFF/ON assessment. The clutch is totally slippable. I have very little clearance in my garage so I have to back my R in REALLY slowly. If I hit the gas, I will probably hit something (one of the thrills of living in house in Japan). So when I back in, I've got to feather the accelerator while adjusting the clutch engagement pressue. REALLY not a big deal at all. If it were an on and off switch, I wouldn't be able to do this. The clutch is grabby but totally streetable. IMO
