I forgot to add, the actual height of it makes it a prick to put the box on if u dont lower the engine subframe

bullshit...ive done a few too....in and out in well under two hours just to check flywheel crank bolts.

that clutch is a little different to the one i have but height looks the same.

Merli wont buy one anyway...he's a bit of a brand whore... :P I bet he wears CK underwear.

i had this arguement with dan aswell.

like him, you can get f**ked too

ATS carbon twin = excellent clutch, only driven 2 but liked them and heard good reports.

OS twin = good for the money. and easy and cheap-ish to rebuild with genuine OS parts (no need to re-line second hand plates with new friction material etc). I've had a few and a triple plate as well.

Nismo twin = excellent clutch too. probably the best street/track compromise clutch.

ORC also make very good clutches. a little more exxy than OS but in my eyes just a bit nicer too. I've even used a blitz/ORC single which was awesome (made like a multi plate but with just one plate if you know what I mean)

I haven't tried the NPC but looking at the pics it's made the right way and has the right ingredients to be a very nice clutch. I would certainly consider one.

those extreme clutches are shithouse. I can't count the number of failures i've seen in everything from silvias, to GTI-R pulsars, to skylines. they are just shit. I wouldn't normally generalise about any brands product like that but I think i've had enough first hand experience of those failures to say so. and having driven on them they are not even nice to drive. shit shit shit shit shit.

be thankful it's f**ked now so you can move on to something nice.

for your car I'd probably just go the OS or ORC twin. or look at price of ATS carbon twin and the NPC twin too. if the NPC twin is less than an OS or ORC twin then seriously consider one. they look very good.

I will still stick with my origanal comment ATS for the win IMHO and as I stated once you use one you will never go back to a conventional clutch 1 of the GTR track cars i have built rego 26R32 has been running one of these clutches for 2 years now and has done a shite load of race klm's is making 500awhp and has never had a problem when the engine was last out of the car the clutch plates looked as if they had hardly worn at all by far the best clutch from my experiance expensive but worth every cent.

Not knowing ANYTHING about carbon clutches, I was a little worried about the durability of them in track/race only applications... But sounds like they're up-to the task!

Looks like there's too long a wait on the OS clutches anyway, so I'm waiting to hear back about availability of the ATS twin carbon and Nismo Coppermix twin.

:P

if you can wait till next week, an ats twin carbon will be up for sale. Darren and I will both be putting getrags in our cars. so it wont be needed.

Merli, Darren certainly knows his stuff and his recomendation would be enough to convince me ATS's are the shiz. Looks like you may be able to pick one up for a good price.

Thanks guys...

Daz has already PM'ed me about it... If I had known about this a few days ago, it would be a no-brainer, but I have already paid for another clutch, so I'll have to see....

Our clutch specialist checked the old clutch and says the 4 spring Extreme are a problem and the 6 spring ones they do are ok. Measured the clamp load to be 1220kg and can increase this and make 6 button, and would be fine, espcially with air cooling we do. I have single plate clutch 6 button in my car for many years and no problem. Heat kills clutches, and mostly sealed bell housing is bad enough for big hp road cars, but if going to the track they get very hot. Get some air in and out is the trick.

How are you getting air to the clutch?

<sigh>

Thanks for the heads up guys...

I've been through seven different twin plate clutches (and one triple) in my travels, some good, some bad, some excellent....

I thought I'd try something new, but after hearing the above reports, I'll stick with the tried and true OS Giken TS2CD. It'll be my THIRD one :P

At least it'll be a known quantity, but I miss out on trying new technology :ermm:

Mine was two or three meetings old and had done some dyno time as well.

It sheared the driving lugs off the two carbon clutch discs. Engine was making just shy of 500Kw. It let go coming out of the pits at wakefield park so I decided that clutch was not the best option for me.

I kept the whole thing but didn't even bother looking into warranty. Its still in the garage in a box.

What was the Torque Output ??? At the Engine ? , so where you running about 650hp ?

Those are some lovley vids (ads) that you have linked to there that are virtually void of any real tech info apart from how a clutch actually works wich I would assume most people in the motorsport section have a fair understanding of. Correct meif I am wrong but I was under the belief that the excedy carbon clutches are not actually a true (100%) carbon clutch. The actual friction material certainly does not look like it is 100% carbon they look like a woven blend of carbon and another material unlike the ATS clutch wich is 100% carbon. I have heard several bad reviews of the excedy carbon clutches but have not used one personally so cant comment from 1st hand experiance with their carbon clutches but going from my own experiance with some regular excedy cluthes theat have not been great and going from the experiance of others I dont think that I would take the chance with my hard earned money.

    • So, I started this repair and got as far as "fixing" the holes with some fibreglass. God all those years working on boats came back quickly. I decided I'd reach out to some rust guys just to see what they would say about it. I came across a guy about 40 mins away and went to see him. He said the windscreen needs to come out, that there might be some more bits around the windscreen and he'd quote them at the time. But his quote was $300 to remove and replace windscreen and $3k for the damage he can see. He said he could respray the roof for $1200 and the bonnet for another $800 (somebody has previously rattle canned it, its horrendous). This is $5300 + any small additional bits. It's a lot, I get that and the name of one of my fave youtube channels 'Not Economically Viable' comes to mind.  I'm not being financially rational, but I've taken him up on the quote. He's opening a new shop in November with more room, so we're waiting for that. I'll leave the currently missing headliner out until then. I'm looking forward to it being fixed and having the paint looking nice again (lots of clear coat issues on the roof too). / flame suit on.
    • Oh and some up-and-comings; New rear drivers wheel bearing. I'll do that this weekend while the diff is out. The car is already up and the d/c axles and missing exhaust will help with space. This is the last bearing for me to do and I've been dragging my feet on it. I also have some new EBC blue stuff pads for the car and some new brake fluid. I haven't ever flushed the fluid in this car and looking forward to it. I have 600 degree fluid to put in. Not exactly "race fluid" but better than the typical stuff I have been using.
    • A proper clutch/plate type mechanical diff with quite a lot of pre-load and high locking % is better for drifting. Much more consistent in its behaviour. A helical can be annoyingly vague and inconsistent in how it responds under the sorts of abuse found in drifting.
    • Some updates here. I pulled the entire interior out, minus some trim to respray the seats with Colourlock dye. It turned out really nice though I accidentally let the dog in the car after and she scratched up the front seat.  This is what it looked like before, the colour was just washing out everywhere but thankfully the leather was in good nic. Then after the respray   And after the bloody dog jumped in The headliner is out waiting to be retrimmed, but it will stay out now until Nov - see why below. I replaced the stereo/headunit with a period-styled Android headunit. I have no after pics, but I'll get some. This is because of the missing pixels. I tried to fix this twice with replacement ribbon cables but couldn't. Also the bluetooth interface I'd bought for this was crap. Then there's the rusty roof. Pics and info in this other thread. I have decided to get this repaired professionally, but I'll update that thread. This is why the headliner will stay out for now. I'll be getting the roof and bonnet resprayed at the same time the rust is fixed. I also had an interesting issue with my drivers door lock.  For a small period I was having issues getting any 12v power to the car - I mean *any*. It would have no dash lights, nothing. It happened while I was at the shops and I couldn't get in the car. So, we had 2 problems. The most pressing here is that I was locked out. I have only a single physical key hole on the car, the drivers door and no amount of turning would unlock the car. Surely it doesn't need power for this? The second issue is why am I losing all power periodically, The battery isn't dead, its almost like the battery isn't even there. Two issues that were surprisingly easy to fix. You fellow BMW over-engineering lovers will appreciate this. The lock in the door has 5 states; mechanical lock, electric lock, neutral, electric unlock, mechanical unlock achieved at -90 degrees, -45 degrees, 0 degrees, 45 degrees and 90 degrees. Although, the unlock is towards the front of the car, so opposite for LHD countries. Sticking the key in and turning 45 left or right is what is used 99% of the time. It activates the central locking etc. 90 degrees is for dead battery access and, obvs, only un/locks the one door. But because the mechanical lock is never used and is 27 years old, it seizes up. I was totally unable to turn the key far enough to get to the mechanical unlock (At the time of locking myself out, I didn't even know this was a thing). I eventually did it with some vicegrips and teflon spray.  I made a quick vid for other E39 peeps.   The battery issue is totally new to me also - It wasn't making sufficient contact between the post and the terminal. The terminal was bolted on tight, but the car wouldn't have power. After checking the battery with my multimeter I accidentally contacted the terminal and the battery post and the car got power. The battery was only a few years old and in good condition. I cleaned the post and the terminal with a wire brush, bolted it back on tight and never had the issue again. I'm still surprised that despite having solid contact it didn't work. Also, the car was getting Warragamba sized pools of water in the back when it rained. My initial concern was another rust problem. But when I went out on Weds while it was raining and while I had no headliner in I could see a steady stream of water coming through the roof mounted aerial. As this aerial is for the (now removed) car phone I pulled it out and whacked a blanking grommet in the hole. It seems fine now. I'm thinking I might get the hole permanently filled when the rust is fixed. Moving forward and things in progress; The tailgate needs some attention. I have taken all the trim off to clean it all and address some small rust spots. I have partially done all of this but I'll finish it up hopefully this weekend. As all the trim are now entirely devoid of trim clips I have bought a heap of strong velcro and I'm hoping it does a good enough job as any of this trim in good condition is super expensive and usually in Europe as we dont have many of the wagons here. Suspension and brakes!!! This is exciting. In the front; New control arms New sway bar links New lower Eibach springs (the only modification I'm planning on this car) M Sport shocks (these came with the car and will replace the longer shocks in the car) New top mounts Used 540i calipers (stock brakes suck!) New 540i disks and pads (22x296 mm for 528 and 30x334 mm for 540i) New front wheel bearings (thank all that is holy for bolt on bearings!) Annnnd in the back; New control arms New sway bar links Adjustable air suspension arms (fool the car into what the current height is so the self levelling suspension can match the new front ride height) New ball joints I'll also be doing a brake fluid flush while I'm in there. I'm planning on switching the car over to the 16's that came with it so I can clean up and respray the M Sport 17's. They've lost a lot of colour over the years and have some gutter rash. None of this will start until the E90 is back.
    • You mean you will regret it for drifting duties? I don't quite follow.
