Hi,

I am looking around for a new clutch. I would like something a bit uprated but still acceptable
for normal road use. I saw the Helix and AP clutches (in Coordpsort catalog) which cost about the
same. I also asked a quote for the Daikin clutch but thar one is more than twice as expensive. All
clutches I look at are single plate for my Evo V RS. Any opinions welcome.

Twice as expensive, thrice the clutch! It will hold everything and retains the pedal pressure and control of OE unit. The Daiken assembly replaces the factory flywheel.

If you have discovered slip while driving hard you probably have overheated your flywheel. I am not convinced that a badly overheated flywheel can be properly resurfaced. The temper of the metal will change. Don’t have a clutch done without addressing this issue. An irregular flywheel surface diminishes the holding power of your clutch and will shorten its lifespan.

I fit a ralliart cover with standard plate but that's only slight better.

I would now go for the ap racing or the helix(is it the one supplied by power engineering?),
but even if it's more expensive the daikin seems to be the best choice(what's the price of it? are we talking of the twin plate clutch?)as it has twin plate and new flywheel and Braf is saying that it's not harsh!

What do you think about the JUN ultra light flywheel at around 250£(4,1kg!)?

I have recently fitted a Helix 6 paddle clutch and am beginning to regret it, it is obviously a lot fiercer, but I believe it's to much for fast road use. I recommend that you call a chap called Dave who is 'the gearbox expert'according to Ralliart and who I found to be very knowledgeable.
I am experiencing a rough sounding noise when I slow down in the gears at low rev's, Dave thinks its because the springs are far too stiff and cause the whole internals to verberate.
Dave can be contacted on 01245 231366

Had the RalliArt three paddle and though annoying I loved the holding power. Got my Daiken and am so satisfied. No chatter, smooth engagement.

I would not recommend a normal paddle clutch for any daily driver. At first you are able to convince yourself that you can tolerate the chatter but it wears thin. You get tired of explaining to passengers why your car is making that atrocious noise. The feel is not acceptable for daily use.

It you can scrape up the cash you may be poor after installation but you will no longer wonder if you have the proper clutch.

Kevin,

Is that the organic or the ceramatellic AP? (that how the ads describe them). I'm getting sick of the abuse my std. clutch won't take.

Hello wheelspinners, From my experience, The AP 4 paddle clutch kit ( inc release bearing)is the best to go for,(try Peter Lloyd rallying for a good deal). the Helix cermetalic is too sharp for normal use, ruins the feel of the car. Get the flywheel machined at the same time, makes all the difference. Steve Hills mechanics can do all this in about 4 hours, makes the rates at main dealers excessive.
My tip for the day: Get the car rolling in first the accelerate full in second, makes the clutch last much longer!

My Clutch is spinning,I have to buy a new onehttp://www.ltregister.f9.co.uk/graphics/embarassed1.gif border|EQU| 0 align|EQU| absmiddle >!!!

OK,I'm thinking about the ap formula organic clutch kit maybe fitted with the jun ultra light weight flywheel,the daiken(maybe a little bit too expensive,what's the price of it?
Is it twin plate?)or the JUN complete clutch.

I would like to go for the best possible clutch that will be ok for every day use and so I'm not sure about the paddle clutches.
Why the ap 4 paddle clutch would be less harsh than the helix or others?

PLEASE REPLY!!! GIVE ME YOUR OPINIONS!!!

The AP clutch I have is the Organic type, IMHO do not go for paddle as they are horrible for road use. I have done a fair few miles with the Helix paddle and did not like it at all.

As always with clutches drive before you buy!
Someones its as smooth as standard clutch is another persons stalling, kangroo-hopping nightmare.

I would try to avoid any paddle clutch on a road car as they usually have a very sudden engagement, a pain in the wotsits for everyday use.

In general:

Clutch material
Organic is the most common clutch material and is your best bet for smoothness or everyday use.
Cerametallic is more durable although the engagement will not be as smooth as organic.

Plate design
Full face is the most common clutch design, it is smooth, cheap but it has limited torque capacity.
Paddle (large number of paddles e.g. 6) has a high torque capacity but the engagement will be sudden. They are prone to squeal and shudder.
Paddle (low number of paddles e.g. 3) has a very high torque capacity but the engagement will be extremely sudden. Due to the high torque of these clutches drivetrain breakages may occur e.g. transfer box or gearbox.
Twin Plate designs should have a near standard feel with excellent torque capacity however they are expensive.

is the daikin a multi-plate asy? We used to race ex2000 with padle clutches and drive them on the road, they were fine no noise, harshness or any thing. are you guys having problems because of the power of the evo's. Having said that didn't Ap use to supply a paddle for road use on the cossy's

Sean,

The Daiken I fitted is a twin disk. You get a new flywheel, two full face sprung hub cerametalic disks, a cover assembly that allows two settings for spring rates and a ventilated center pressure plate.

The stock clutch is fine at stock power but won't let you get the car rolling quickly. It needs to be nursed along.

With the Daiken in you can launch at 5k feeding in the power and spinning all four as the car does its vanishing act!

....and shag the transfer box along the way http://www.ltregister.f9.co.uk/graphics/sad1.gif border|EQU| 0 align|EQU| absmiddle >

Remember that manufacturers clutches on high performance cars are designed to be the weak link in the transmission. Uprating a clutch will mean it may no longer be the leak link in the chain. It is better and cheaper to replace a shagged clutch than a shagged transfer box. Twin plate clutches (Daiken or RS) or full face organic (AP) should be OK but paddle clutches can put huge strain on the transmission.

I did consider changing my clutch but I have decided against it.

HH6,

Certainly breaking the drive train is a possibility but the late model Evo gearbox has proven quite strong.

I am hopeful that by getting the tires spinning the moment of maximum load should be brief.

I have been warned repeatedly by many that what I am doing to my car will break it. After three years I still take note and realistically recognize the possibility. I promise all on the Register that I will let you know when I do manage to break it. Just consider me a research project. Nothing lasts for ever.

The Daikin guy still hasnt replied, I guess they dont wanna sell their clutches to people in Monaco...

Patrick,
I totally agree with youhttp://www.ltregister.f9.co.uk/graphics/biggrin1.gif border|EQU| 0 align|EQU| absmiddle >!

I'm doing exactely the same thing(testing the resistance of the parts),even if it's getting expensive!!!

I would like Claudius to help me,but he is only interested by testing the resistance of the standard parts[img]http://www.ltregister.f9.co.uk/graphics/sad1.gif border|EQU| 0 align|EQU| absmiddle >.

I don't have a reply from the guys of DAIKIN,but I'm really interested on that clutch!
Did you bough it directly from daikin or from another supplyer?
Can you tell me the price of the kit?

About the two different spung center settings,did you go for the softer one?

Thank you for your help!

And also is the flywheel lighter than the standard one? if not,can it be changed for a JUN one or is it really specific to the daikin clutch?

Maxi,

The flywheel is Daiken specific. If there is any total mass difference it seemed minor to me. The two spring settings are achieved with a spacer that fits thicker when inverted. You select the setting prior to installation. Check your hotmail account.

What is the difference once you are driving the car between the two settings? Does it feel harder, harsher, stronger, etc or something? Can you launch it better? Or what? Thanks
