Need A New Clutch?

[Harey]

Just ordered an organic 34 GTT clutch with 3300lb of clamping force. Should be fine for 250rwkw (hi flow turbo). Quoted $935 exchange delivered plus $275 deposit until I return my one.

Standard clamping force is 1600-1700lb and they have roughly 140-150rwkw stock, so double the clamping force is roughly double the power. So should handle ~280rwkw.

Cant wait to see how it goes! Sick of the revs flaring under a hard 1-2 gear change

put a jim berry clutch in my car just on a week ago now and it is the best clutch iv'e ever driven on, it's a single organic and it's street car friendly but it grips real well too, good customer service, i think it's good too put your trust for a product into a person who's had the experience a guy like jim has had

Ok got the clutch installed yesterday. After copping lots of abuse from the japanese mechanic about why I didnt just fit an exedy HD clutch. He kept saying that I fit another standard one, I kept saying no its not standard etc etc.

Whatever, so I jumped in the car and first of all thought they hadnt actually changed the clutches cause it felt the same as standard driveability wise. Drove sedately for a while and yeah the gripping point is very slightly narrower but not noticeable. The driveability is sensational.

Then came time for the real test, gave it some stick in first and went to do a quick change to 2nd, clutch grips and the rear wheels start spinning / axel tramping! Mind you I only have 190rwkw so Im not testing it out power wise but what a difference.

I have put more power to the side now, next issue dam AXLE TRAMP!!

So far the clutch is exactly as promised, very happy. Dont listen to silly mechanics!

After plenty of reading on a clutch upgrade for 250-260rwkw for street/occassional drag runs (just to see what the power feels like legally ), I just want to know what the difference between a button clutch and a jb clutch (single plate?) is..

My ATS Twin Plate Rebuilt by JB is in transit, after speaking with Jim I'm sure it will do everything I want it too for a very long time.

Come with insurance in the form of Front Gearbox Seal and Rear Main Seal,

Awesome to deal with and Quick turnaround!!!

Hey ppl, another vote for Jim's clutchs. He rebuilt my Nismo single plate to 3200lb's with an organic plate. It is no heavier then it was originally and it's great on the street.

Hey

Just got a nismo twin super coppermix compertition version. Arrived the other day will let you all know how it goes.. can't wait

Cheers

[Marko R1]

I've heard very good things about the nismo coppermix, I am still a massive fan for the jb full monty

I'm running 405awkw with 930nm and this single plate with 4400lbs pressure plate holds like my os giken triple plate and exedy twin plate BUT drives almost like a factory clutch!

I will never buy another multi plate clutch, dreadful to drive...

[SiR_RB]

i spoke to jim berry last week, told him my plans with the car etc and he recomended an organic plate with 3800 lbs clamp load

i told him i wanted a street friendly clutch that could handle 300awkw for the future/no track use

great guy to deal/talk with, got the clutch coming end of next week

[full_stick]

Had my full monty for about 6 months now, got about 350awkw on high boost. Have never really challenged the clutch, never dumped it, hasn't seen a single track day so just day to day street driving. First launch (low boost) it died, I too am very very disappointed...

[Marko R1]

that is surprising - did u install the clutch?

one of the tricks is to use graphite powder for the thrust bearing slide rather than grease as directed by jim berry...have u spoken to jim about this?

im sure if its a mechanical fault he will look after u

[full_stick]

I have spoken to Jim and he was quite helpful but the conversation was predominantly about fault finding the clutch issue which I documented and provided the clutch specialist who installed the clutch initially. I'm waiting to hear back from clutch specialist as he said he was going to speak to Jim about so we'll see what happens after that conversation...

[scarface_au]

Definitely sounds like the guy to talk to. I can afford a decent clutch but don't anticipate putting a lot of power through it for a while so I'd like to get something tough enough to handle normal street driving with a fairly stock RB26. Doesn't need to be able to handle massive power yet as by the time I can afford those engine mods I'll probably be due for my next clutch. I just want something reliable ... the one I've got has a firm pedal but I'm used to it now, so as long as it's not worse I'll be happy.

+1 for Jims clutches. Full Monty 4300lbs carbonic 5 puk sprung center, feels like a stocker.

Over a year of absolute punishment with over 500rwhp.

Stock flywheel.

Broken 2 boxes and 1 diff with this clutch

When using the "full monty" and driving in traffic do you take car out of gear and take foot off clutch pedal when stopped moving...?

Mine was great I loved it and was raped everytime I drove the car. Would do standing start powerskids in 3rd gear and never slipped (drop clutch in 3rd) and 4th gear clutch kicks @ 100kph.

Shame about the broken gearbox parts..... but was great fun

[NYTSKY]

My clutch has a twin brother lol

My clutch has a twin brother lol

It was the best clutch ive ever driven.... But now I have seen the light after the expenses of rebuilding the 25 box numerous times and have fitted a C4 and 3800 stall

[r32silvergts]

hey guys having a problem with my r32 GTS seems to have slack in the drive train because when im doing 60km/h on constant throttle on flat or down hill it seems to well i gues the best word to deskribe it is bunny hop but it it only slightly still verry anoying i thought it was the diff because i knew it was buggered but new diff in today and all the other clunking has stoped but this problem still persists. i am having slight trouble with the idle control valve thing cant remember exactly what uts called so it could be the engin doing something funny but i realy think it is drivetrain related rather than engin related. any idears? also idle control skrew wound all the way in and i cant get idle any lower than 1500 RPM any idears?

[scarface_au]

Tried calling Jim yesterday and he hasn't replied. Is he normally hard to get hold of?

[skylinecouple]

Well, after installing my Jim Berry clutch I figured I'd better jump on the bandwagon. Guys, if you ever do one decent mod to your car, get the Full Monty. Drives so much like stock I almost wanted to rip it out cause I thought it was defective. I don't ever recall my standard clutch being that light. Oh, ok, it takes up as quick as the Exedy cushioned button I had in it but after the initial run in period it is just perfect. Money well spent. At first I was dissapointed when I put the money into Jim's account and half an hour later I get a phone call from someone to say he has a twin plate for me. But as I said, I am so glad fate made things work out the way they did. Take my word for it, spend the money, get a Full Monty.
