NPC make some of the best clutches around. Their twins are used in 1000+hp cars. I run an NPC single with 600hp no problems !

only a single.... launchs, drivability ?? do you know if they are like the Jim Berry ones which have mega clamp like the one I have now with 4200lbs clamp, feels like a sledgehammer hitting the drivetrain ?

Having used both Jim Berry single plate and NPC id have to say that both are excellent in high horsepower applications. My current NPC twin plate cops over 1000hp every launch and is nice and quiet unlike the Jap items that have that annoying rattle.

Has anyone had any good or bad experiences with the NPC range of twin plates..........

or what about nismo coppermix twins are they rebuildable ???

I had one in my rb30/26 running 580hp and the preasure plate smashed after a week and destroyed my gear box. I was only running the cluch in no launches at all. It was a single plate 5puk from npc

ive used alot of clutch brands and my npc twin is by far the best drivability and ive never had any hint of slip with 600rwhp, 1750kg car and revlimiter drag launches with a dogbox. I have used an os giken quad and it was annoying to drive, on and off engagement which sucks. The NPC is so smooth to engage and its such a soft pedal feel considering the power it can hold. I would have no issue using it as a daily driver clutch its great.

Ive also used direct clutch twin plate, extreme singles as well to compare.

They are cheap too compared to the jap brand options so its definately got no compromises.

From the last time it shit its self I sent it back and had it rebuilt to handle even more power. Funny thing is I'm running less power then last time. Now 450hp and the piece of shit clutch let go yet once again but this time it smashed the box clean off the block. I was changing from 2nd to 3rd. I should of learnt work's the first time it let go. Now I will use what I know works. Hks or os or a orc so I don't have to pay labour to remove the gear box and pay for a new box and clutch because some price of shit clutch can't handle half of what it is built for. Buyers be warned. And customer service is f**ked when you send them back. They try anything to get out of it

was this the NPC 10inch ceramic button sprung clutch? I'm having one installed in my GTR today (380awkw) - I hope to God that I don't have the issues that happened to you. I guess I'll find out soon enough lol

basically I just wanted a quick swap over clutch so I didnt have to leave my car at a shop for a week or two while my OS Giken twin plate gets rebuilt. I was told this clutch can handle 600hp at the wheels - so I thought I would try it (cost were much cheaper than the NPC twin). At worst I can always get the OS Giken reinstalled (after rebuilt) if I'm not happy with the NPC 10" ceramic button sprung clutch.

I'll do a review on the NPC 10" ceramic button sprung clutch after I run it in - will post it on this website. Hopefully my pressure plate won't explode.

Ah fair enough

Not sure if theres any difference between the GTR and GTST clutches, but mine has a lighter pedal feel than my old exedy cushion button, isnt to much worse to live with every day (takes a little while to get used to but not so bad)

Bites damn hard, and has never slipped for me once. Going strong for over a year now.

I dunno what else to say about it lol

      Cleaning my wheels 😍

      By Milkmun · Posted

      Can't say I've had a bad experience with one on my car, then again it only gets washed once or twice a year... The wheels on the other hand, get a good spray often due to my shitty dusty pads.

      @MBS206 thats pretty neat and tidy to me!  I'll get a photo of mine when I'm out there next. It might require multiple photos to understand the scale of the atrocities though... In total I have 4 sheds of varying sizes and layouts. Main shed is 14x8, second shed is 3x8, third shed is 11x2.5, fourth shed is around 6x4.  All are pretty much full.   The main goal of my cleaning tsunami is to make the main shed predominantly car and motorbikes only. Second shed is my metal fab room (2 x bench grinders, drill press, bench belt sander, metal band saw, scrap metal storage and some of my garden tools.  3rd shed is more bigger garden stuff, storage for engine crane, jack stands, concrete grinder, concrete mixer, air compressor lives there, and it now has two 2mx2m pallet racking shelves with itemised boxes holding building stuff, electrical stuff, plumbing stuff, etc, etc.  The 4th shed is Ryobi electric ride on mower, mini boom sprayer, ancient Kubota tractor, more garden stuff!  I have got a lot of shit....  Then there's the pool house (8mx4m) and the pool pump shed (4mx4m).  I built all of the sheds over the 11 years we've been here.  The main shed was a Ranbuild kit, the rest are all custom made to fit the areas available. Building the main shed taught me a LOT as I had no idea about building anything prior to that!  I've still got one more in me. It will be my man cave which I poured the extra concrete for way back when I poured the concrete for the main shed. The idea is the Skyline will be a centre piece of the main cave once (if...) it's finished.  I told my now 14 year old son yesterday that I will 100% drive him to his year 10 formal in 2 years. Still a long way off but at least I now have a date to work towards! 🤣

      Modern oils are amazing. Add tyres to that as well.

      Probably a smart choice to buy one vs build, purely for the motivation part as you said! Imagine the metal dust everywhere from grinding all the steel to build one. Ha ha ha!   Also, post a photo of your garage.   Mine is below, this is where I've been cleaning and have already half filled a caged 6*4 trailer. And this is after my cleaning expedition mentioned previously... The middle normally has a car in it, but I'm dumping things in the middle as I sort through them. And poor skyline was dusty and has had the lightest few drops of rain and now it looks atrocious and needs to be dragged back out and washed thoroughly! And yes to the right is technically another bay, you really can only see 2 bays out of 3 in this picture.

      It's more like on average the things I see a lot of things going wrong. Yes, usually the people who reach out are the ones who are having problems but on average it feels like mechanics and tuners here aren't really competent. I swing between thinking my standards are just way too high and wondering whether people really are just this dumb. I just had the strangest 10+ reply argument on a Facebook group over someone insisting that the factory R34 GTT boost control solenoid reduces boost pressure to 5 psi when it's on and raises boost pressure to 7 psi when it's off despite showing the exact plumbing in the factory service manual and the solenoid behavior detailed in the FSM.
