Hey guys,

Just woundering...Has anyone got a OS Giken Triple plate? What are they like to drive around? when i pulled the clutch apart i noticed that none of the clutch plates had springs. But do the 3 plates compensate for having no springs?

Am i going to have driveline problems? Is it a ON/OFF clutch?

Any comments welcome.

Cheers,

Trev

I ran an OS triple plate in my GTR for quite sometime and it was fine.

It was one of the most pleasent clutches I've driven considering it was a triple plate and my car is driven on quite a regular basis in peak hour traffic.

Unlike other clutches I have used, the OS isn't an on/off clutch and there is some slip there if you want it.

I think you will find that most triple plates are unsprung as it would only mean that more space is required to fit the springs.

Just a note, you won't really need a triple plate in a RWD until you are making over 400rwkw so stick with a single or twin for drivability sake.

Thanks Leewah,

By the way was the clutch noisy? In terms of the clutchs rattleing around?

Also im not sure if you will be able to ansaw this, but: I have bought the Triple plate of a R32 GTR (RB26), and the clutch will be fitted to a RB30 Crank. (It doesnt quite fit, needs about .50MM machined of the crank were the pressure plate fits.) Anyhow, i am using a stock RB25 tranny. Now because the clutch has a double diaphragm, i think it would be pretty heavy on the fork inside the box, is it nessacery to strengthen this? also will i have to machine anything on the inside of the box (e.g snout?) or should the clutch fit straight on?

Cheers,

Trev

Surprisingly, the clutch wasn't that noisy considering it was a triple plate.

All multiplate clutches will make the rattling noise when the clutch is in but it was a noise I could live with. People will tell you that the car is making funny noises but it's just a given that they'll make noise when the plates are rubbing against each other.

As for the fitting of the clutch, you'll just have to muck around with it. You seem to have bits from all types of Skylines but most parts are interchangable if you can be stuffed machining them. Sorry but I have no idea about the stress on the forks. Someone else on these forums maybe able to answer this question.

I have got HKS Triple plate in my gts-t and must say they are quite a bit of overkill for a gts-t unless you're doing a lot of drag racing. Also the triple plates tend to have a lot smaller amount of pedal movement between being disengaged->slipping->fully engaged. Gearshifts are a hell of a lot quicker with the triple plate though. I think the HKS kit cam with fork and thrust bearing and rose bearing. I would definately recommend upgrading the clutch fork though if it didn't come with one as the triple plate is a lot heavier than the standard clutch.

      GOT SUM's RB34

      This morning I carefully reinstalled the manifold and started looking at a couple of things I need to do.  Heat wrap arrived sometime today so I popped into the shed with the missus dishwashing gloves and started wrapping the first half of the dump and the screamer/plumb back.  Once I do the second half I'll be able to final fit the turbo and exhaust up.  Also pulled the harness out today and started terminating it at the ECU end. A connector is done, just need to run the remaining wires that arent in the harness - 12v, gnd and couple I/O

      Thanks for all the replies! I also wanted to ask if wheels that were fitted on Ford Falcons would fit the 350GTs as well? In the area I'm at there aren't that many options for secondhand wheels and new ones here are way out of my budget. From what I've seen, most of the wheels that are available that were fitted on Ford Falcons have an offset of +33 to +36, with a centre bore of 70.5mm whereas the stock 350GT's ones are 66mm, can't seem to find any hubcentric rings that fit that difference though.

      215/45/18 tyres are probably a little on the low side compared to the factory tyre, it should be closer to a 245/45/19, which will get you about an extra 11mm of height, and should make you speedo read a bit closer to reality. 245/45/19s will be a bit too far the other way and you risk a speeding ticket as your speedo might read slower than your actual speed.  245/40/19s would be correct if you are going to 19in rims, they will give you a similar total diameter to the 245/45/18 tyres.

      That's something I forgot to put in my list. The aggressive anti-squat in R32 is a f**king menace. I still need to decide if I'm going to drag the subframe out of my car and weld in the GKTech corrector kit. The main reason to dither is the need to switch to spherical joints in the lower arm to account for the twist induced in the rear pivot caused by lowering the front pivot. And yes...we do put better subframes in R32s, and I wish I'd gotten an S14 one instead of an A31 when I did the "take off and nuke it from orbit" HICAS delete all those years ago.
