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.

    • The rain is the best time to push to the edge of the grip limit. Water lubrication reduces the consumption of rubber without reducing the fun. I take pleasure in driving around the outside of numpties in Audis, WRXs, BRZs, etc, because they get all worried in the wet. They warm up faster than the engine oil does.
    • When they're dead cold, and in the wet, they're not very fun. RE003 are alright, they do harden very quickly and turn into literally $50 Pace tyres.
    • Yeah, I thought that Reedy's video was quite good because he compared old and new (as in, well used and quite new) AD09s, with what is generally considered to be the fast Yokohama in this category (ie, sporty road/track tyres) and a tyre that people might be able to use to extend the comparo out into the space of more expensive European tyres, being the Cup 2. No-one would ever agree that the Cup 2 is a poor tyre - many would suggest that it is close to the very top of the category. And, for them all to come out so close to each other, and for the cheaper tyre in the test to do so well against the others, in some cases being even faster, shows that (good, non-linglong) tyres are reaching a plateau in terms of how good they can get, and they're all sitting on that same plateau. Anyway, on the AD08R, AD09, RS4 that I've had on the car in recent years, I've never had a problem in the cold and wet. SA gets down to 0-10°C in winter. Not so often, but it was only 4°C when I got in the car this morning. Once the tyres are warm (ie, after about 2km), you can start to lay into them. I've never aquaplaned or suffered serious off-corner understeer or anything like that in the wet, that I would not have expected to happen with a more normal tyre. I had some RE003s, and they were shit in the dry, shit in the wet, shit everywhere. I would rate the RS4 and AD0x as being more trustworthy in the wet, once the rubber is warm. Bridgestone should be ashamed of the RE003.
    • This is why I gave the disclaimer about how I drive in the wet which I feel is pretty important. I have heard people think RS4's are horrible in the rain, but I have this feeling they must be driving (or attempting to drive) anywhere close to the grip limit. I legitimately drive at the speed limit/below speed the limit 100% of the time in the rain. More than happy to just commute along at 50kmh behind a train of cars in 5th gear etc. I do agree with you with regards to the temp and the 'quality' of the tyre Dose. Most UHP tyres aren't even up to temperature on the road anyway, even when going mad initial D canyon carving. It would be interesting to see a not-up-to-temp UHP tyre compared against a mere... normal...HP tyre at these temperatures. I don't think you're (or me in this case) is actually picking up grip with an RS4/AD09 on the road relative to something like a RE003 because the RS4/AD09 is not up to temp and the RE003 is closer to it's optimal operating window.
    • Either the bearing has been installed backwards OR the gearbox input shaft bearing is loosey goosey.   When in doubt, just put in a Samsonas in.
