Getting Rid Of Clutch

[2rismo]

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" ......

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.

[Cain]

i was looking @ a JB clutch, but the single plate i have in their atm sucks *extreme* so i bit the bullet and got a ATS carbon twin plate with the carbon coated lightweight flywhel and pressure plate, Im hoping this will be better clutch. wasnt cheap tahts for sure

[elrodeo666]

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...???

[TommO]

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?

600rwhp and dragging/street... my jim berry would be the only clutch i would use now, previously had some nismo shithouse, absolutley hated it.. everyone is different i guess

[elrodeo666]

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

[Beer Baron]

if you are in japan, and want good driveability get the nismo supper coppermix twin. excellent clutch.

[elrodeo666]

Cheers Baron..been looking pretty much that..yeah I'm in Japan..6 years too many but still helluva alot of fun

[Ronin 09]

+1 for super happy coppermix twin

awesome

[Pal]

my extreme 9 puck has just failed after 2 years and by the sounds of it a jim berry is at the top of the list. How do we get in contact with him/them.

[dangerous_daveo]

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.
