alright well in preparation for getting my t2 together im looking for a good streetable twin-disc clutch setup. the only one's i seem to run into are exedy, hks, and OS. i've heard that exedy is the best one but would like to see other opinions.







also any idea on where to get a good price for an exedy unit, or any good streetable twin-disc?







kevin.

my buddy swears by os giken. he ran the os twin in his fc ,from what he has told me its very very streetable and extream high grip. he ran a tilton also and not to streetable and a few others but the os he liked the best

tilton makes one too.



ive driven the OS its actually pretty nice, little grabbier than stock, but not much

What do those run new?

I had but never drove an OS giken...

exedy is $1500-ish for the twin disc. i think OS is aroun d the same price.



i cant find anyone who actually stocks them tho.



kevin.

did you try world pac?

i have the OS in my car, drives REALLY nice, it does make a little bit of noise with the pedal in if that sort of thing bothers you. The plates rattle a bit. Pedals is very low effort and its super easy to drive.

I haven't driven the twin disc yet, I was leaning towards the HKS unit originally...but after reading a lot of posts from FD owners, the OS Giken seems to be the weapon of choice.



I'm in the same boat as you though, can't find somebody who stocks it...

Quick search, I came up w/ about $1500 for the OS unit:



http://www.xspeed.com.au/shop/product_info...products_id=719

they do list it, although it looks like they dont have one in stock. hard to tell though

$1500 would get you a nice custom unit, far better than something off the shelf...

1Revvin7: Including flywheel? I'm pretty sure the HKS unit doesn't include the flywheel thats why i've avoided that one, the OS and Exedy units come with a billet "explosion proof" or whatever flywheel so i've been looking into them. Of course you have to supply your own auto counterweight tho.



I'm not so much worried about the price, i'd rather pay and do it right then do it cheap and continue to pay for it down the line, ya know?



Rob: who is worldpac? cant browse the web right now, busy here, but im guessing worldpac.com...ill check it out later maybe give them a call see what they say.



One320B: if you're interested in the exedy unit gothamracing.com lists the twin for the FC's at $1500 that's the whole unit (flywheel and discs) but like i said before for all of them you do have to obtain an auto counterweight.



djgiantrobot: i don't mind noises, it isnt a daily. more of a racer that id like to take out for a fun weekend drive or travel to some shows around our area in. Good to hear nice things about OS tho, it seems with OS either people like it or hate it some complained that there was a lot of pedal effort.



From what ive read briefly people say the exedy is "easier" to drive but im not positive on how long it'll stay "race-ready" for if you know what i mean. The OS i've read is moderately more pedal effort but supposively very strong and streetable as well.



If worst comes to worst i'll buy it through gotham if its in stock.



kevin.

worldpac is like the super awesome place for shops to get parts.

Kevin if you are interested shoot me a PM.



Yes with a flywheel, and yes you need your own CW.

Excedy or cusco, same thing, are good. I ve got one in my fd works perfect easy to drive , only down side its heavy . But the weight is close to the middle. And is way smoother than hks or os twin plates ( have friends that use them and they shudder hard when they got to hill start and the hks one has stuck a few times after burn outs) .

i'll contact you soon, my daily cars are giving me trouble so i have to dum,p money into them first. ugh./







kevin.

I thought the HKS came w/ the flywheel... hrm.



I've got an Centerforce Dual Friction unit now that I'll be selling in lieu of a twin disc setup. The centerforce only has 200 miles on it, but i dont think it will take the abuse of a t78...

my centerforce couldnt handle a t04e, and there are a lot of documented problems with those clutches.. i.e. the face falls off.







kevin.

Lol, great... I just put mine up for sale in the for sale section, now nobody will want it,lol...



To defend the clutch though, we had one in a friend of mine's '94 Cobra w/ 300ftlbs or torque and it lasted a while.. and this past weekend we just put another one in an '93 Cobra... we shall see how well it holds up.



They are good clutches for a mildly modified T2 (running stock turbo) or under 300whp...

yea i dunno if it was a temporary bad production run or something but when my centerforce fell apart a couple guys on the forum told of similar experiences. havent heard much about it since, and it seems popular with most cars.







i loved my 6 puck tho.







kevin.

Teknics..if you find somebody who is willing to do a twin plate cheaper if you get two..maybe we could work a deal... I'm down for OS or HKS...

ill definitely keep you informed if i find it cheaper, depending on price 1revvin can get me I might go with a custom one, and i figure 2 at the same time could cut a few $ off the price.







kevin.

I just purchased a ORC twin disc i havnt installed it yet but it was a pretty good deal so i didnt want to let it pass me by. i have a quick question about it kinda freaking me out its a orc709 and has looks like it adapts to a 6 bolt but my stock flywheel only had that 2 1/8 inch monster on it. I wont be installing it back on my na cause im getting a t2 s4. but ive seen a picture of the stock t2 flywheel looks like it also uses the monster 2 1/8 inch.

to bolt it up you need to buy an automatic transmission's counterweight which bolts onto the flywheel and has the 6 bolt pattern for the flywheel to mount to.







i had to take the counterweight off my N/A (switched from light to stock) the other day. had to use a slide hammer and boy did that sucker hit me in the back of my head hard.







kevin.

thanks alot bro that wont through off the balance though because ive been told the twin disk is balanced to itself. thanks for the help guys.

Exedy Hyper Twin $1430 from Rotaryextreme.com



I'm going with one of these with my new A-spec 500r setup.

What is the cost on their 500R setup?

no but it doesnt have to do with the balance of the clutch setup. you *need* the counterweight to be able to mount it to the car. it balances the motor.







kevin.

my os gilkin twinplate mounts to a automatic counterweight, it isnt balanced itself in any way.
