New Twin Plate Clutch, Very Bad In Rush Hour Traffic

[Abo Bob]

If I drive my GTR often, the ORC twin plate is great. It's only when I'm not thinking that it bites me.

The most annoying part about it that's dificuilt is that the friction point is more than half way out on the clutch pedal.... so you have to keep releasing your foot to almost the end of the pedal travel. That makes it hard to find and hit's as a surprise sometimes.

If it was closer to the firewall, it would be so so so much easier.

However, I've fallen in love with the clutch and wouldn't go for anything else now.

I didn't realise you'd bought a GTR Tommo.

My clutch was like this until about a week ago. I adjusted it at the pedal. I had to loosen the bolts holing the master cylinder to the firewall to make room but yeah, do that then take the pin out of the pedal connecting to the rod and shorten it there. Put the pin back in, re tighten the nuts holding the master on and happy days are yours.

You do it the long way around Adam.

All you have to do is: undo the 12mm nut that locks the shaft and then use a little offset spanner ( i cant remember the size but I think 5/32) , turn the shaft then lock the 12 mm nut again , takes about 2 minutes. It takes me longer to find the correct size spanner than to do the job!!

Oh no way! Dammit!!!! Now I know. haha.

I know exactly what you mean but didn't think of it myself dammit.

You can always ask mate .. Ah well you know for next time ....Keep in mind that in all cars its an easy to do job, a bit like changing a light globe, you should never have to remove the light assembly to do it....

im good at driving the twin plate, just hill starts to always get me, i always have to concentrate, and even then i stall!, i hate it, any tips for hill starts, im gnna take my car to a quiet area with a hill, and start praticing!

I only bought it a couple of weeks ago actually... got sick of the evo, it's great to be back in a skyline... albeit a slightly quicker one this time

Thanks for the advice on the clutch - i'll have a look at that option this weekend.

I reckon the 'ol handbrake hill start is the easiest. Keep the handbrake on (no foot brake) and feed out the clutch until the rpm drops a smidge and you can feel the xar move a fraction. Then at the same time, release h/b give it a touch more throttle and feed out the clutch, and woila! you're away......

You can go with the excess throttle and clutch dump, but that attract a bit too much attention at times

Are you serious? Handbake starts are for learners only . If you can't take off without resorting to handbrake buy a subaru liberty, they have a built in hill start , you can't roll back !!!

[nsta]

hahaha, my clutch hates the car rolling back(even the slightest) and then me giving it throttle, it just stalls mate.

Unless you can find the precise spot halfway up the travel of the pedal where there is 1cm of movement from off to on; without going too far and stalling it, or too slowly and youve just rolled into the car thats up your arse.... All clutches werent created equal, some are harder to drive than others, as its not my daily driver i dont know the car inside and out. We cant all be perfect. The handbrake works so it use, less rpm, no rolling backwards, less clutch wear.

I use my handbrake on a lot of my starts. I find it easier on the clutch.

very well said, though i use mine day in day out, and most hill starts i dnt need the handbrake for , those steep hills though, man they are a bi#ch to start on!try paralell parking on a hill with a car infront and behind, now that takes some effort on a twin plate clutch hahaha

A friend of mine had one of these Coppermix twins in his 32 GT-R- It was heeeaps nicer to use in traffic than my old Exedy twin.

I'm sure you'll get used to it.

Hi Guys,

Ive got a HKS twin plate in mine and before i read this article i though i was the only one who used to stall it....

As for the friction point is right up the top.

WRXHOON, with the 12mm nut i take that off and do i turn the shaft clockwise or anti-clock wise........sorry if this was a silly question....

You don't take the 12mm nut off ( you can't take it off even if you want to) you undo it a little so you unlock the shaft.

Depending on what you want to do with the pick up point, if you want to lower the pick up point you shorten the shaft and lengthen it if you want the clutch to grab higher.Keep in mind one turn of the shaft will make a fair bit of difference .

Cool Thanks man will try it out

[pekkis]

Iam now driving with exedy gay triple plate, it is gayest clutch ever. you let the pedal up... and then... nothing nothing nothing nothing and then ALL are in. Dont even want to get used to it. I bought nismo coppermix twin and nismo slave cylinder. I will get them in 2 weeks. Hope it is easier to go. Someone are saying nismo coppermix twin is on/off clutch, and someone says it is very driveable in traffic.... so what is it like??

[Cubes]

How long has the clutch been in?

They are all very very very grabby initially and then they smooth out so to speak.

....I bought nismo coppermix twin and nismo slave cylinder.

Interesting....I have just installed one of these clutches and when reading the documentation it specifies not to use the Nismo slave cylinder due to lack of stroke volume.

I have a Nismo twin coppermix in my car, Its the best twin I have ever used in any car. You can drive it in taffic very easy but don't expect it to be same as a normal full face clutch , its very close to it though. Don' t ride it and it will last you a long time . I have a the Nismo slave as well and makes feel more progressive , no issues with travel.
