He's using Redline Lightweight Shockproof oil; it is blue in colour.

I recently installed an NPC 10" organic in mine; they rate this clutch to 300rwkw (I'm currently 250-260) and the pedal is half as light as the Exedy cushion button I replaced with it. Say goodbye to my left leg muscle! It does bite firmly when you get to that pick up point, though :)

Yeah the NPC feels as if it's broken, it's so light for a sports/race/enthusiast clutch. I honestly thought the fork slipped off the thrush bearing and I was shtting bricks.

So far it's pretty good, unfortunately the R33 I own now is stock (for now) so I can't really punish the clutch.

How do you like daily driving the button clutch? is that cushion button so you can have some slip with it?

I'm still tossing up between going their organic or button will only be putting out 270rwkw when tuned and car is mostly daily driven just when I do drift it I want to know kicking it won't be an issue. I also don't drive heaps or cop lots of traffic driving so I don't think a button clutch would be a major problem but do like drivability at same time cause i'm a big girl

Dont be crazy with it yet. I ran mine in for 1000km as suggested (no major clutch slipping or launches) and I dont know if it makes a difference but I'd rather listen to what NPC told me and follow their procedure

I dont know if mine felt THAT soft lol, think its a bit harder then stock but def nicer then the exedy

If you're drifting, an organic clutch is bit of a no no, you'll fry it. On my previous R33, I made about 250rwkWs and I toasted an organic within 1.5 years of owning it. I then moved to Exedy Sports Ceramic from a R32 GT-R, that lasted till I sold the car (probably still going strong), however it was crap to drive. Wasn't fun, especially with the stock slave, after upgrading to a larger Nismo item it felt better, but still not that great compared to this NPC clutch. It's very light, nearly as light as stock and more easier to slip and drive.

Saying that, I've always tend to just give it some revs and drop it to get the car going. I know it's jerky, but it's going to save me going under the car and do a clutch again on the floor.

I have a 10" carbotic button clutch from NPC in my gtr. I never saw easy driving from day 1. Only time will tell how well it will last, but 5000km and its still going strong. I drive my car every day in stop start bullshit and there is no problem. Just use the friendly handbrake when on a hill. In these early mornings it loves to chatter and bite harder than when it warms up.

So far it has held 10 launches and many wot runs. I recommend them.

the reason the NPC clutches are lighter then other sport clutches is due to the 10 inch pressure plate and larger spring area.

i have a 180sx with an RB30e+t and NPC organic clutch with rb20 box... i drift it and clutch holds up well, that makes around 200 rwkw

I am going to give him a call to sugest something to hold 500kw dont know if i am looking at twin plate territory

Definitely twin plate territory.

Most of the Japanese twinplates won't even hold that much power for long due to them using tiny clutch plates

NPC sprung centre cushion twin is the way to go. Drives like a toyota hi-ace and will hold 1khp to the ground

Just an update, after 1 tank of fuel later the clutch feels much better.

I still am totally impressed with the pedal feel, but it is a tad bitey. I tried going up a car park ramp, I looked like a total idiot LOL

Yeah after a long drive yesterday mine is feeling so much better.

I just got a clutch from KB clutches in Sydney.

He was a really nice bloke that asked everything to do with the car and the power/rpm/use

Managed to pick something up for $410 including postage to ACT

Only time will tell if it holds up or not.

But I currently am pushing around 240-250rwkw

i got my 300 RWKW clutch from KB aswell, held out with no issues and came with few exeddy bits too, i paid 440 delivered to SA

Just an update, clutch seems to be more easier to drive or it just could be me getting used to it. Still need to chirp the wheels a tad getting up ramps when I'm stationary, but much easier than my old car with the Exedy Sports Ceramic.

Getting my NPC 10" carbotic clutch installed tomorrow. Will see how shit i am at launching it when the drags open up in a few months. Current excedy ceramic button lasted 2 years of every day driving, skidpan days, drag nights, clutch kicks, etc. This NPC one holds 450rwhp im told, so should keep me happy for a while!

    • They are what I will be installing. 640s for me.
    • Hmm... From my experience you get about 0.25° camber change per mm of RUCA length change. So, to correct from -2.5 up to less than -1° (or, more than -1° if you look at the world as a mathematician does) then you'd be making 6-8mm of length change on the RUCA. From a stock length of 308mm, that's 2-2.5% difference in RUCA length. My RUCAs are currently very close to stock length - certainly only 2-3mm different from stock. I had to adjust my tension arms by 6mm to minimise the bump steer. That's 6mm out of 210, which is 2.8%. That's a 2.8% change on those, compared to a <1% change on the RUCAs. So the stock geometry already has worse bump steer than is possible - you can improve it even if you don't change the RUCA length. If you lengthen the RUCAs at all, then you will definitely be adding bump steer. Again, with my car, I recently had an unpleasant amount of bump steer, stemming from a number of things that happened one after another without me having an opportunity to correct for them. I only had to change the tension arm lengths by 1mm to minimise the resulting bump steer. (Granted, I also had to dial out a lot of extra toe-in in the rear, and excessive rear toe-in will make bump steer behaviour worse). Relatively tiny little adjustments having been made - the car is now completely different. Was horrifying how much it wanted to steer from the rear on any significant single wheel bump/dip. And it was even bad on expansion joints on long sweepers on freeway entry/exits, which are notionally hitting both rear wheels at the same time. My point is, the crappy Nissan multilink is quite sensitive to these things (unlike the very nice Toyota suspension!). And I think 99.75% of Skyline owners are blissfully ignorant of what they are driving around on. Sadly, it is a non-trivial exercise to set up to measure and correct bump steer. I am happy to show my rig, which involves nasty chunks of wood bolted to the hub, mirrors, lasers, graph paper targets and other horrors. Just in case anyone wants to see how it is done. I'll just have to set it up to take the photos.
    • What do you have in that bad boy ? Ill go with the 725cc since I'll be going with Nistune ( would definitely like more engine protection but Haltech is too far out of reach at the moment... plus, Ill probably have a pretty safe tune as its a daily, not gonna be chasing peak power 24/7 ahahah ). Are Xspurt a safe choice?  Pete's great. He didnt mention anything about traction arm length so I reckon it may be good. When I get some new wheels/tire later down the road I'll ask him about it and get his opinion on em. I heard from Gary that you've got the bilsteins too, are you running the sway bars too? and what other suspension goodies do you have installed or would recommend?
