I reckon the Exedy will have a short lifespan as i think they are only rated to 330rwkw so i am pretty keen to see what all the NPC hype is about, they sure sound good and are HEAPS cheaper than what i paid for the damn Exedy!

Everything used in the NPC clutch is Exedy parts.

Doug modifies them to suit the application though. Nissan Patrol hub, 250mm plate, 350Z 250mm pressure plate etc

Oh... Well that is interesting! I should contact him and see what he says about mine and wether i should start thinking about it now or just let the other one go and see what happens....

If im looking at over 300 in the next few years does it seem worth me getting the 10" sprung carbotic over the 10" organic? Or would that be overkill for me? its a daily with 2-5 track and drag days a year. From what i have read the organic is rated to a bit over 300, just worried if i go for 330 next year that the clutch wont take it too well.

Got in touch with NPC

Hi Johnny,

I would recommend our 10 inch heavy duty carbotic button clutch kit.

$755 inc gst for the kit.

To give you some idea the clutch has 1700kg of clamp load & will hold 400rwkw.

I would be lying if I could tell you how long it will last. I would expect allot longer than sports organic.

Thanks,

Doug

yeah thats spot on.. same clutch i run. i dont daily my track car but i did do 300 kms of street driving in tasmania in it with no probs haha

That's bullshit he's lying.

They definitely hold 450rwkw for a long time, 2 step limiter launches, nitrous enriched 2nd gear multiple clutch kicks, power skids and seasons of track work.

I don't know why he would mislead you like that. I told Doug ages ago how f**king good they were

I have one of these. Street is no biggy but with the extreme cold weather in the morning it needs 5 minutes of nurse driving then it becomes fully streetable. Handles all wheel launches and anything else Ive thrown at it. Been in for 4000 km so its still early days.

Why? Shudder?

Yeah but I guess he is being slightly conservative.

After all if you give a dickhead an unbreakable object, my money is on the dickhead.

That is true.

As a matter of fact, a customer who is new to button clutches is more likely to kill it with kindness rather than abuse. Riding it too much is a killer.

I would ask Doug if he can make you a 6puk plate instead so its easier to drive and definitely go carbotic over ceramic. It's a little bitier but definitely handles the heat better

I don't really ride my clutches usually it's a on and off love affair with me :)

I'm just waiting on Doug to see if he can also get a gearbox front seal kit & stronger pivot bolt and it's on like Donkey Kong! If the clutch is too heavy, I will upgrade my slave to a Nismo item, like I've done in the past.

Doug builds clutches. Why not just go to Nissan for your seals and gasket?

The clutch pedal will most likely be lighter than your existing clutch. They are almost lighter than a standard HD. You won't need a pivot ball. Just lube it properly

Nissan spares are only open weekdays and unfortunately I work a boring desk job in the city. I might just go through Kudos and order it.

I've heard horror stories of stock pivots snapping with heavier clutches, on my previous R33 I went all anal and replaced the pivot, slave, seals etc.. lol

Tried searching on Amayama.com? Ive had a few good purchases from them..... Not always cheaper but a couple of items have been WAY cheaper and just as fast to get as Nissan were even from JP

It's on like Donkey Kong!

Just ordered it, now I need to clean the BBQ and buy a slab of beer to bribe a few mates to drop the box. I wish I still had access to a gearbox stand & hoist makes life so much easier :unsure:

    • It's excellent but I'm still breaking it in so I'm not 100% sure where it'll end up. I would say it's about 15% heavier than stock and the smoothness of the slip zone is quite progressive but you need to be a little patient compared to stock or it'll bite hard and stall. Stock I got away with absolutely horrid clutch control. Like I said before I couldn't even tell where the clutch would grab when it was stock so releasing way too quickly without enough revs it would just slip and the revs would drop lower than ideal but that would be the end of it. Currently there's a bit of a nasty clutch judder if I don't apply enough revs + find the exact wrong point of the slip point in the clutch pedal but it feels like it's slowly resolving as I drive it more. I would not recommend the competition clutch unless you really need the extra clamp force. I think this clutch combined with the Nismo operating cylinder is going to be exactly what I want. Enough bite that you need to remember the release point to avoid stalling or rough shifts, but progressive enough that it's not hard to drive by any means and not heavy at all. I tried a "super single" clutch on my friend's 997.2 Turbo 6MT and that was absolutely horrid. It runs an electrohydraulic power steering pump for the clutch power boost so there's zero feedback in the clutch pedal and there was a horrific clutch shudder well after break-in due to the lack of marcel springs or hub springs in the friction disk. It felt like the slip zone was the thickness of a single toe twitch as well so it was almost impossible to avoid stalling it unless you gave it a ton of revs and just dumped the clutch instead of trying to be smooth with it. I was terrified of pulling out in front of traffic. I have also tried some kind of "super single" on an EK9 and that makes this twin plate Coppermix look like a stock clutch. Releasing the clutch pedal even slightly too quickly feels like you're getting rear-ended. The pedal is extremely heavy as well and there's no vacuum assist like the GTR.
    • Yeah, well I was probably way underguessing the $300 figure anyway. Just multiplied a "normal" by 4 for the purposes of pointing out it's not cheap, particularly if it has to be repeated.
    • We have an alignment shop out here that does what you're talking about but he wants like 800 AUD a pop. DIY is "cheaper" but once you start accounting for the value of your time I'm not sure it's worth it.
    • The main catch phrase for any car is "the eye of the beholder", and "personal tastes and preferences" And as for the plastic "flares", I honestly think they look cheap and tacky, and I cannot see them aging well, maybe if they were body colour they might look better to my eyes, but, I would still prefer it the were more like the older WRX STI models that had the wider body metal panels In saying all this 5hit, I wouldn't buy a new WRX again, even if it had the wide body metal panels
