Jim Berry? U can't beat it mate, I know first hand from running the full Monty on my 3ltr and now the 'super Monty' on my current setup :)

I honestly don't like them. I've driven a few and found them too aggressive. Nismo hands down, only issue is that I need the centre to mate up to the rest.

3 months on, jim still hasn't got back to me if he can do what I want.

However, his clutches won't slip. It'll spin the earth backwards before It slips. Haha

What about the os quad plate? Is that more driveable then the os triple plate? I've been considering an os88 and matching clutch for mine as well.

From the incar videos ive seen it seems very civilised as far as dog boxes go

There aren't many around that don't show the cars going full throttle. Bobby posted one the other day on the highway which made it seem quite smooth and ive seen Harlow-Jap-Autos post a video of them moving an r33 gtr around in their show room.

Both videos are on facebook i'll try to find the links now

Here it is

Sorry im not sure if it can be imbedded. Looks far more streetable then any dog box ive ever had the pleasure of using!

Yeah I love the gear indicator placement unfortunately r34's dont have that spot haha

Ideally first hand experience would always be best however from my experience with dogboxes (ranging from harsh to super harsh) the os88 in that car just looked like a synchro box with a sequential shifter!

Give me a drive?

I'm yet to drive a jb clutch that drives half decent.

Also depends how the disc is setup, some clutch shops bend the plate ever so slightly as it's engaging (for normal driving) the entire friction material isn't biting on the flywheel.

I had an off the shelf NPC clutch and it drove exactly the same as a JB clutch, either ON or OFF - although the pedal felt like as if it came from a Yaris but the clutch was horrid to drive and you would either bunny hop or chirp tyres taking off a decline no matter how hard to tried not to.

Then I brought the car to Western Clutch to replace my clutch (long story - mixture of cbf and time) and it turned out nothing was wrong with the clutch plate and pressure plate - was a mixture of wrong parts installed from the previous owner and when I replaced the clutch I used the same fork, bearing carrier, etc..

Anyhow, Scott modified the plate and pressure plate.. clamp is now at 1.7 tonnes ( from 1.95 tonnes) and the clutch feels like a corolla clutch. Same pedal effort as stock FWD car, and you can easily ride it too.. no stupid bunny hopping or wheel chirping like a tool.

What he did to the clutch plate was bend it ever so slightly, so on a light clamp - say taking off the entire friction face did not engage with the fly wheel.

Food for thought, could be totally useless for your requirements.

Thing is, it's not like you're trying to find someone with an OS 5 speed. These things ain't cheap. I might flick Bobby a PM.

One question I do have, whats the 'nicest' way of going from say 6th to 2nd. Is it a simple case of clutching in and pushing the lever up or should you try and match the revs with your right foot? You cant exactly clutch in, neutral, rev, clutch out and put in the next cog like you would a dog box.

    • I am yet to see anyone ever regret a quaife or helical. ...other than drifting/skidpan duties. I kind of want to upgrade my factory helical with a Quaife (but really it's not ultimately that different, and is a MASSIVE UNDERTAKING), that's how good the hype is about them, that I want to try them 'just to see'  
    • D2 and Ksport are essentially the same thing and basically just generic Taiwanese manufacture. Better than ChinaBay crap, but... not top shelf. Öhlins have got to be some of the best dampers around, so likely to be a good option. It's going to get to the point though where I suggest you buy from Oz. We have at least 2x excellent options here. If I were you though, I'd be talking to KW about doing something for the R33. There's bugger all difference between that and the 32. In GTR land, anyway.
    • KW only offers a set for the R32 GTR. Popular options are D2 racing, Ksport or Öhlins. I have a D2 Racing coilover set, though I don't know for sure which one.
    • Well, the good news is you have more than one very good option for new coilovers in and around your country. Worth the drive over to KW to talk about GTR stuff.
    • Fair enough, I am in no way a tire expert so I'm not familiar with all the terms and conditions. I'll definitely note down the AD09 to potentially try in the future. Rain is not too big of a concern for now as I will probably only drive in the rain when I have to. And considering I still lack experience driving the GTR I'd more than likely take it easy too. I have coilovers in the car but as I barely got to drive so far I never bothered to even check if they are adjustable haha. The suspension is almost entirely old and worn as well so I suppose when I eventually fix that in the future that would make a huge difference.
