Between a exedy hypertwin and the uniclutch, uniclutch is nicer.

Clutch pedal is definitely lighter, I've only put 3000km on the car but I'm happy with it atm.

what car ? what power ? pics ? more details PLEASE :D

Have you given it any abuse? 

I.e. on the track (as in circuit not the silly roll race "track"), big RPM, big down shifts, etc. or any skid pans/drift days?

That's the testing I would like to hear about.

Not yet, it got tuned with this clutch and made 480rwhp.

I've got it off the road atm to sort out the fuel lines and hopefully make a touch over 600rwhp.

I'll be taking it to the drags and drifting once I get it sorted.

Ist post I joined after seeing this thread 

I have just installed on a r33gtst

at first I liked it but I am finding the peddle free play changes …. To a point I have had a zero free play condition and the thrust bearing stayed engaged. I had to back off the adjustment on peddle.  
I am about to change slave and fit a braided line to see if I can get a better result

I wouldn't be surprised if this helps. And I wouldn't be surprised if it keeps changing for a bit after the new slave&hose go on, because I find that my clutch always does this sort of shenanigans after any serious dismantlery. And then it settles down after a few corrective tweaks such as you've already done.

I hope so.  It seems pretty nice. OEM feel the lot.

Did you get the sport or track ?

From what the documentation says the uniclutch has a small amount of movement to disengage. 

So your story of tricky pedal setup seems common. 

 

Hopefully you got it bled up too, as the bite point moving around is usually either plates wearing in or air in the line.

Sport. I didn’t rebleed it cause I just removed the slave and left connected. 
 

I will change line and slave and see how it goes.

Ok so I have sorted everything with my uniclutch and  i can offer up a bit of feedback and some things that might help others. 
 

I found problems with factory damper line. Weird shit and had trouble with peddle adjustment 

 

I used this https://au.gktech.com/products/r33-gts-t-skyline-braided-clutch-line?_pos=2&_sid=22b01b9b9&_ss=r

Also when adjusting peddle leave a bit of play. You can get into a over stroke condition easy.. Make sure you can push the slave forward after adjusting to confirm fluid can return to master then you will need to pump it up heaps…..not sure why but that’s how it is. 
 

last thing the splined adapter is machined perfectly. If your input shaft is old like mine was I would put a bit of valve grinding paste on it and stroke it like a 15 year old. Just to give it a tad more clearance and to better match it to the spline. 
 

reason is on a near flat shift I have had situation where the peddle returns a millisecond after you lift from the clutch. No slip or anything but I reckon this is due to tolerance on the spline being way tighter than stock clutch and binding for a sec. I think this will go away but also my spline was old. Box is old so I guess I should have checked better. It’s a super neat fit. 
 

it feels light as and holds awesome without any noise

I'm about to swap my box to Tremec T56 Magnum F & initially thinking of re-using my DCS twin plate (can get it re centred for the bigger spline) but it's been called out the box will be noisy (rattle) as the clutch is unsprung. 

So I'm doing as much research as possible. I'm not so worried about holding the power as I'll go the track version which on paper will hold the maybe 1000hp I make. It's the longevity I worry about. DCS told me they don't use a sprung centre as it's just something that can break. The uni clutch has a very complicated sprung centre. Any one had or heard about any issues with it failing?

Thanks in advance.

      V36 2008 Coupe Wiring Differences with Android Screen

      Right, here's a video of the basic operation at least.  This is what you can expect day to day when you turn the car on and it boots from standby.  The only thing from a media point of view I haven't gotten working is for it to autoplay plexamp when it turns on from standby (it works from cold boot) but that's more of a plexamp problem as it will autoplay other music players.  Also attached is my one stray cable.  It's part of the screen's wiring adapters but there's just nowhere for it to go in my car.  I've just now done a bit of research and found a matching port on a 2010-2014 head unit with BOSE.  Mine has no BOSE so that's that case pretty much closed I think.  Plugging in the Infiniti AC panel basically did nothing for me, so that's a dead end as well.  Next port of call is to mess with this CANBUS module and see what I can find from it.  I found this resource containing the DBC files for a 2010+ G37 : https://github.com/icecube45/Dash_InfinitiG37/blob/master/InfinitiG37.dbc I'll now have something to go from when I try to extract my CANBUS data so I can see if the HVAC Mode, Fan Speed, Temperature, etc. match and also the gear shifter position.  It's a pretty big assumption that it's just mismatched CAN signals but considering all the devices in the CAN network are talking to each other (AC can be fully adjusted just with no info on screen) it might be a safe one.  I will report back WhatsApp Video 2025-02-26 at 12.49.10.mp4

      Thanks for that Paul.  Do you think if I posted a picture you'd be able to remember where it went?

      Sorry Duncan, I didn't get a notification for the replies.  Thanks for responding!  It's a full Android device, but does allow you to use CarPlay/AA as well.  This is the one I bought from NaviRS on AliExpress: https://www.aliexpress.com/item/1005006368602668.html?spm=a2g0o.order_list.order_list_main.111.59aa1802JDzQ0E - the 2K 8G-256G CAM variant but it seems to have gone up by £170 since I bought it!  My purchase was ￡307.14.   It's not the fastest thing in the world but performs perfectly adequately.  It stays on standby unless I disconnect the battery and let it power down, then it's just a fairly standard Android bootup time from cold.  The DSP Equaliser is very nice and made the standard stereo system sound pretty decent compared to the stock screen.  Perhaps I can take a video of it when I get a sec. It *allegedly* supports the reverse camera, but I'm yet to get that working.  It has options for reverse cam (a camera unit can be bought separately) or 360 cameras (also bought separately).  To be fair it doesn't seem to detect that the shifter was put into reverse but I'm working on a theory about this as well.  At the moment I'm going without which is a bit annoying considering the car is an absolute canal barge but so far I haven't caused any damage I'll grab a picture of the wire I'm missing later today when I can get outside.  My theory, by the by, is that not only is the head unit different, but the CANBUS network has different signals for the different years.  I think this because I have a spare AC panel from a newer Infiniti G37 (as opposed to my Nissan panel) which wouldn't control anything except the volume when I had it wired up with the stock system.  I'm going to throw it back in and see if the screen will respond to it.  I've just ordered an arduino CANBUS module so I can have a look at the signals going around the car and see if I can spot anything.  I'm thinking if I can work out what it's expecting vs what it's getting I might be able to translate and relay the signal back but so far just a theory anyway. I also found this on my travels, so far the only one that specifically matches my car: https://www.aliexpress.com/item/1005002822934280.html?spm=a2g0s.imconversation.0.0.33433e5fgttovi If you look at the picture of the before, it has the card reader slot, and the picture of the head unit is exactly the same as the one pictured in my original post.  I asked if they sell the cables separately but sadly they won't.  I didn't want to just buy this one because it's a super old Android version and only dual core - likely slow as hell.

      As above, you did refill the coolant and burp the system before running it again didn't you?

      To be fair - you see the same thing for every clutch. There's always someone making an installation error.
