Off the top of my head Maatouks racing use jim berry clutches just set the new record for fastest manual vl using a r33 box the clutch still feels awsome in this thing.

My car will be getting the same clutch

They sure do and if I'm thinking of the right cars, they're both of their manual VL's are now in the 9's.

n00b do u even knw wat a jim berry is

Yes I had 2 of em fail on me "n00b" :D ......

2rismo - well I stand corrected, still it would be interesting to see the reliability of a single plate at these power levels compared to multiplates - particularly in a AWD application.

I'm not saying that in all cases a single plate should be the first option. It's more a case of people jumping to lesser quality multi-plate setups simply because they're a multi-plate. Assuming that a twin is better than a single for all occasions is flawed. That's my point.

It's a different world, mate and you know it. Can I walk into any Autobarn and buy a custom made clutch to my specifications from any of the major manufacturers you mentioned? If so, then you already understand the benefit of a clutch built to suit the application and I don't understand the blanket recommendation that other brands are superior to his clutches.

Blanket statements are what destroys otherwise sensible advice on internet forums.

you miss my point completely... 99.9% of readers on this forum will get a better clutch all round from something that comes mass produced in a NISMO, ORC or ATS box than a jb clutch..... the other 0.01% would not be taking advice off here.... a custom clutch would be relevant to less than 0.1% of SAU members

Yeah that's a fair call - the multiplate I was referring to was a NPC unit, not the junk ones. Likewise there seems to be a lot of misinformation about the capabilities of single plates on this forum & from people who sell them hence all I say is buyer beware, they're not the holy grail in clutch options if you got decent power IMHO (if they were I'd still be happily using one :( ). People don't appreciate how cheap it is to have a NPC twin plate rebuilt as opposed to a single full-monty one which is a consideration if you are keeping your car long term + giving it regular punishment.

And you missed mine, champ. Broadly speaking, anything purpose built is better than anything generic and off the shelf. It's just common sense.

thats absolute bullshit, you telling me a nismo coppermix twin or ATS or ORC for the avergae skyline making 500hp is not purpose built??? if you are you are brainwashed beyond belief. in my experience going the proven route is always a winner, some random (not talking JB here)slapping together a clutch will often end in unsatifactory results.... direct clutch is one perfect example there... got f**ked around for months trying to get a decent clutch to handle 500hp in the RX7 and in the end an ORC worked perfectly and my old lady even drove it to the shops... the GTR has a nismo coppermix twin in it..... stock pedal feel and no dramas handling 350rwkw..... the old lady uses it daily.

custom is a needless waste of time unless you are doing something out of the ordinary....

Stacey and i raced on the same clutch for 3 years...450AWKW...and lots of abuse.

then had it rebuilt for $300 and it now lives in another 400+ AWKW R33 street car.

no problems

They sure do and if I'm thinking of the right cars, they're both of their manual VL's are now in the 9's.

They sure are should be a great day out at the creek tomorrow and something different from me when i get my financial situation sorted cant wait to get my beast out

Wouldn't a single plate clutch be better than a multiple plate in regard to plate inertia? When changing gears there would be less inertia load on the syncros?

A competitively priced multiple plate, not an expensive lightweight one. Also its easy to have a sprung center with a single plate, some multiple plate jobs have solid centers and thats it.

Gave my car pretty hard run tonight and clutch is starting to slip off hard launches so looks like time to upgrade. Looking for something that is good for daily driving and can be used for the odd track day as well.

The JB's sound good but I live in Japan so getting one over here could be a bit of a hassle. I've been looking at the Nismo copper mix but being here in Japan got access to all the jap tuning makers. Nismo garage is just 5 minutes down the road and HKS 15mins..

anyway any reccomendations or advice be great..what about HKS clutches...???

I've only used an ORC but it's really nice to drive with once you get used to the friction point :) I've driven a mates car with a OS Giken and that was nicer again... same grip level but friction point lower to the wall.

Not sure if friction points are set by clutch type / brand though, or install... anyone know?

It's pretty hard to sort whats good and whats not..I'm definitely after driveability..drove a V spec 33 with a triple triple plate, car was standard bar coilovers and it was hell to drive..Yeah maybe get used to it but living where I do in japan I got 4 bitching months of snow and ice to contend with so a clutch thats user friendly is important.

What sort of weight is the Jim berry as far as postage..i can workout a cost for sending to japan..Main thing I suppose is only looking at mods for say 4-450 HP so any recomendations be great..

By the way drifting in the snow is a hell of alot of fun

I think some of the issues people might be having also with their clutches. More so the top end ones (not just the JB ones) where they SHOULD work. I think could be their installation, and transport prior to install.

When I picked mine up from Jim he made sure I had a good solid box to transport it in so it wouldnt get damaged in the car, he wanted to know the mechanic putting it in etc. I would assume other clutches would appreciate the same treatment.

Not knowing how some of these off the shelf items are packaged or transported, but potentially they are getting damaged slighting in transport. When in such high power/stressful applications that slight damage is more apparent and the clutch fails or doesnt perform how it should.

Either way I'm very happy with my clutch, and more so the service that was provided.

    • Who did you have do the installation? I actually know someone who is VERY familiar with the AVS gear. The main point of contact though would be your installer.   Where are you based in NZ?
    • Look, realistically, those are some fairly chunky connectors and wires so it is a reasonably fair bet that that loom was involved in the redirection of the fuel pump and/or ECU/ignition power for the immobiliser. It's also fair to be that the new immobiliser is essentially the same thing as the old one, and so it probably needs the same stuff done to make it do what it has to do. Given that you are talking about a car that no-one else here is familiar with (I mean your exact car) and an alarm that I've never heard of before and so probably not many others are familiar with, and that some wire monkey has been messing with it out of our sight, it seems reasonable that the wire monkey should be fixing this.
    • Wheel alignment immediately. Not "when I get around to it". And further to what Duncan said - you cannot just put camber arms on and shorten them. You will introduce bump steer far in excess of what the car had with stock arms. You need adjustable tension arms and they need to be shortened also. The simplest approach is to shorten them the same % as the stock ones. This will not be correct or optimal, but it will be better than any other guess. The correct way to set the lengths of both arms is to use a properly built/set up bump steer gauge and trial and error the adjustments until you hit the camber you need and want and have minimum bump steer in the range of motion that the wheel is expected to travel. And what Duncan said about toe is also very true. And you cannot change the camber arm without also affecting toe. So when you have adjustable arms on the back of a Skyline, the car either needs to go to a talented wheel aligner (not your local tyre shop dropout), or you need to be able to do this stuff yourself at home. Guess which approach I have taken? I have built my own gear for camber, toe and bump steer measurement and I do all this on the flattest bit of concrete I have, with some shims under the tyres on one side to level the car.
    • Thought I would get some advice from others on this situation.    Relevant info: R33 GTS25t Link G4x ECU Walbro 255LPH w/ OEM FP Relay (No relay mod) Scenario: I accidentally messed up my old AVS S5 (rev.1) at the start of the year and the cars been immobilised. Also the siren BBU has completely failed; so I decided to upgrade it.  I got a newer AVS S5 (rev.2?) installed on Friday. The guy removed the old one and its immobilisers. Tried to start it; the car cranks but doesnt start.  The new one was installed and all the alarm functions seem to be working as they should; still wouldn't start Went to bed; got up on Friday morning and decided to have a look into the no start problem. Found the car completely dead.  Charged the battery; plugged it back in and found the brake lights were stuck on.  Unplugging the brake pedal switch the lights turn off. Plug it back in and theyre stuck on again. I tested the switch (continuity test and resistance); all looks good (0-1kohm).  On talking to AVS; found its because of the rubber stopper on the brake pedal; sure enough the middle of it is missing so have ordered a new one. One of those wear items; which was confusing what was going on However when I try unplugging the STOP Light fuses (under the dash and under the hood) the brake light still stays on. Should those fuses not cut the brake light circuit?  I then checked the ECU; FP Speed Error.  Testing the pump again; I can hear the relay clicking every time I switch it to ON. I unplugged the pump and put the multimeter across the plug. No continuity; im seeing 0.6V (ECU signal?) and when it switches the relay I think its like 20mA or 200mA). Not seeing 12.4V / 7-9A. As far as I know; the Fuel Pump was wired through one of the immobiliser relays on the old alarm.  He pulled some thick gauged harness out with the old alarm wiring; which looks to me like it was to bridge connections into the immobilisers? Before it got immobilised it was running just fine.  Im at a loss to why the FP is getting no voltage; I thought maybe the FP was faulty (even though I havent even done 50km on the new pump) but no voltage at the harness plug.  Questions: Could it be he didnt reconnect the fuel pump when testing it after the old alarm removal (before installing the new alarm)?  Is this a case of bridging to the brake lights instead of the fuel pump circuit? It's a bit beyond me as I dont do a lot with electrical; so have tried my best to diagnose what I think seems to make sense.  Seeking advice if theres for sure an issue with the alarm install to get him back here; or if I do infact, need an auto electrician to diagnose it. 
    • Then, shorten them by 1cm, drop the car back down and have a visual look (or even better, use a spirit level across the wheel to see if you have less camber than before. You still want something like 1.5 for road use. Alternatively, if you have adjustable rear ride height (I assume you do if you have extreme camber wear), raise the suspension back to standard height until you can get it all aligned properly. Finally, keep in mind that wear on the inside of the tyre can be for incorrect toe, not just camber
