Have always rated the Exedy well and recommended to others, despite never fitting one myself.

Now my time has come.....
Been running an ADL Blueprint OE Spec clutch for around 6 years and 31,000 miles.
In this time it was initially running 270BHP, then upto 310BHP/305ftlb for about 3 years. The last 2 years 335BHP/310ftlb.

Clutch has finally started to slip 4th.....

I am soon dropping a larger turbo on and am aiming for 350-360BHP.

So do I go for an OE Spec Exedy, the Stage 1 or maybe more ??

Cheers

Hi Scott, I would recommend the Exedy Uprated Organic with the anti-judder friction plate. A good clutch that works well: AZTEC PERFORMANCE ONLINE STORE - WHOLESALE PRICES DIRECT TO THE PUBLIC - Clutches & Lightweight Flywheels :: Subaru Impreza :: Exedy Uprated Organic Racing Clutch Kit - Pink Box - Anti-Judder - 5 Speed

Mine judders like a bitch, A mate has the API version and that is almost as bad, I will be trying something different (make wise) when I next change my gearbox.

There appears to be an anti-judder version available, is that what you are running

You need to take into account the condition of the flywheel. No clutch AP, Exedy included will cure judder if your flywheel is past its best.

At the OPs level Exedy organic would cope fine

David at APi good to speak to about this

As I have said before on other threads. It's curious that it has been reported by a 3rd party that the APi clutch judders, when the owner of said clutch has never reported it as juddering directly to APi

I seem to recall it was 50-50.

Even so, if someone gets a faulty product, they usually complain even more if the original transaction didn't go as planned.

FWIW I have an Exedy organic from David on an Impreza with 340+ bhp/torque. I got it originally because the std OEM item was juddering when cold. THe exedy unit has been on there 30+k miles now, never judders and handles the power torque just fine.

David,

Just to clarify, I am the owner of said clutch.

For the record I am complaining about the judder on the clutch you sold me. Are you willing to replace?

The reason I did not complain about the £300 part, was due to the f*cking about I presumed I would receive from API, as per purchasing! Presumably it would have gone along the lines of "Well you didnt fit it correctly.......it must be your flywheel......yada yada yada".

I seem to remember the 'BAD' dealings being considerably less than 50:50, allow me to expand;

1. API charged £40 more than Aztec for some special machine work that eliminated clutch judder......that hasn't.

2. API sent a clutch that didn't fit.

3. API (David) then, after I took my car apart to fit API's clutch and found it didn't fit, tried to tell me the clutch did fit. After David spoke to various mechanics I was again informed it would fit. I distinctly remember having to say "Its like putting a round peg in a square hole" before you were willing to accept it was wrong.

3. After informing you I had a trackday on the Sunday, you were willing to send a new clutch out. Unfortunately, what I received did not resemble a clutch. It was an incorrect delivery.

4. After finally receiving the correct part, it was fitted and then juddered.

5. I then called API numberous times to arrange the clutch return, being told each time you were on the phone and leaving a message for you to call me. You didn't call so I emailed which you also ignored.

6. Then after I gave up, you decided to charge me for the second clutch and send me a bill.

The only thing I can commend API on is refunding the clutch which I should not have been billed for.

As a regular RCM customer I am used to excellent service, Scooby Clinic have also been more than helpful of late. The same I personally cannot say for API and I will not come back again.

Sorry to lay it on the line David, I know a lot of people hold you in high regard, but to come onto a public forum and start questioning why I didn't bring the clutch back, after the initial dealings boiled my blood somewhat!

APIDavid

iTrader: (4)

At last, a voice that I can respond to.

The original clutch was incorrect we know that, but if I recall it got caught up in a week where we had 11 parcels delivered wrong all over the country and we moved heaven and earth to get them where they should be.

At that point, it was discovered that the clutch that arrived wasn't a pair, but had an inorrect friction disc, in fact it was the one from a 2.5 WRX, we eventually discovered, but that at the time we didn't stock, or even knew we had. We attempted to get a correct one delivered on the Saturday a.m. to get you to your track day, but after that we had no more contact. I think I posted on here at the time that we assumed it had gone OK.

I sent emails and letters written to your home address asking for the return of the clutch disc. We only had a house phone number and obviously during the day no one answers. Neither did our mobile contact number for you.

After no responses, I probably sent a letter by recorded delivery.

I even went as far as to say in one letter that unless it was returned, we would assume you had used it and therefore it needed paying for.

It was only after we forced the issue by charging you for it that we suddenly got a phone call saying that you should have sent it back.

It came back, we refunded you and all moved on

So, A mess.

But, had I been told that the eventual clutch wasn't up to the job we would have dealt with it properly and correctly, after all it was allegedly a faulty product.

David APi

Bo_Duke

OK David let's put the past behind us.

Many thanks for the response. How would API like to proceed with replacment of said faulty product?

Well, it's parts warranty, so l need the clutch back here for inspection together with its flywheel and we'll move on.

That can be done two or three ways;

Take the clutch off and return it and we'll sort out what's what and if appropriate, send out a free replacement.

OR, you can have a clutch sent out immediately, pending an inspection of the 'faulty unit' that will arrive after the new one is installed. The problem that people don't like about that wa, is that the replacement clutch needs to be paid for and if appropriate, a refund will be issued.

Or you can bring the car here for the work and just pay the labour charge for the removal and installation of the clutch / flywheel. That is done at warranty labour rates which is £36.00 + VAT per hour, instead of £48.00 + VAT per hour . 4.5 hours will be charged.

Not sure about Scoobyworld, but the Lateral supplied one will be the same as ours.

AZTEC PERFORMANCE ONLINE STORE - WHOLESALE PRICES DIRECT TO THE PUBLIC - Clutches & Lightweight Flywheels :: Subaru Impreza :: Exedy Uprated Organic Racing Clutch Kit - Pink Box - Anti-Judder - 5 Speed

Correct, Exedy UK do an uprated anti-judder friction plate, which is what we sell with our uprated 5 speed kits. Exedy OEM replacement clutches have never been an issue.

Bo_Duke

David,

Taking the nugget of information from Bob'5, before we go down the route of costing me a lot of time or money to resolve this problem....

Is the anti-judder version 100% what was supplied by API? Can you say with 100% certainty, given the mix up's we had? (and the extra $ I paid for it over Aztec's version)

I seem to recall you commented they are sent somewhere locally by API for remanufacter of some description to cure the judder.....

Dave

APIDavid

iTrader: (4)

Dave , We have the friction discs re-lined here in the Uk with competition material supplied by Valeo [ who seem to be the name in clutch friction, similar to Gates are for Cam belts.]

We supply nothing else on our uprated kits. Just occasionally when we get caught short for stock I do supply AP racing friction discs, which actually cost a lot more than the APi version. But an outstanding order needs to be filled ASAP and we take that on the chin.

You will have had an uprated one - no question.

The key to anti-judder is as simple as having a good flywheel surface to run the clutch on in the first place. We do say at the outset on our sales description that we would be unable to support a claim for judder under warranty, if the flywheel is not either skimmed or replaced at the same time as the clutch. Common sense really.

The other thing that can cause judder is poor fitting and letting the weight of the transmission hang on the clutch splines whilst it is battled into place. twist the friction disc and it will always judder, no matter what or who made it.

Dragging the box onto the engine by pulling it in by the clutch housing bolts has a similar effect.

I have no idea what bob'5 stuff is all about, so cannot comment upon his clutches at all.

David

How come when you get them hot, ie slip the clutch a bit they work fine. Well for a short time.

Its almost as if you clear/clean the build-up off the flywheel.

Can you explain this?

To me it doesnt sound like alignment as you can make the judder go away.

I'm convinced its a material issue giving symptoms, much like you get when your brakes pick up, how many folks thought they had warped discs when infact it was pad deposits.......... Clean them up and there fine!

As for poor fitting, it was lined up using an old cut down input shaft,Using a resurfaced fly, the box fell on easy

APIDavid

iTrader: (4)

It isn't alignment in use it is alignment when fitting. If the disc is not centralised really well when fitting the box the first time ther is a chance to twist the friction disc on the way in. First time you press the clutch pedal it will align itself properly, but it may not have been that good by eye.

It is also the weight of the box hanging on the spline whilst fitting if all doesn't go smoothly while fitting for the first time. Once distorted they will never straigthen.

The grip/judder thing will be heat related and frankly it can go either way: get better or get worse, no way to tell what it'll do 'til it does it.

All will be revealed when the disc is inspected by who ever, a bit like fingerprints they tell a story from what you see.

Thanks for the info. A bit of a shock coming on here today to see all this kicking off. i guess thats why I don't come on here so often these days.

Good to read you also had a blueprint, sounds like they cope for a few years.
Mine done 'the ring' last year and a few weeks back the brakes stuck on after a wash...bloody Brembo's (car was sat in the garage for a week with wet brakes). Needless to say a few revs, a touch of clutch slippage and smell was required to back the car out of the garage. that was probably the finalnail

We've only just started doing the anti-judder version, so unlikely yours will be as you ordered yours back in 2008.

I have the exact same clutch as yours on my own car.
