mate there is an OS dealer in Aus too. www.otomoto.com.au

Rebuilding your OS clutch with exedy bits will not give you a new OS clutch. Just like rebuilding your HKS turbo with Garret parts does not = a new HKS turbo. If (when) I need to rebuild my OS twin plate, I will buy the new OS parts for it. no stuffing around.

1. there are two types of OS Giken twin plates, one is rated at 550 bhp and the other 700 bhp in a GTR (4wd and extra weight) so slightly more for GTST (2wd and less weight).

2. lots, we have had 650 bhp for 2 years in a circuit race GTR using the 550 bhp OS twin plate.

3. my local clutch shop put new linings on the OS Giken clutch plates, no problems.

Hope that helps

Hey SK, how did they reattach the clutch plates, and what material?

No one down here has the 1mm thick plates.. or know how to attach it?

The OS Giken clutch linings are bonded onto the disk on the road (lower power rating) spec multi plates, they also have coil springs for taking up the shock loading. The race (higher power rating) specs have no coil springs. The splined centre is rivetted to the disks. So the process is to drill out the rivets, keep the spined centres and replace the disk and linings with new parts. The equivalent Daikin parts fit pretty well.

Hope that helps:cheers:

      That’s a great deal and I would jump on it if you were closer. Melbourne is a bit of a hike for me though unfortunately

      Fake ARP bolts?

      By soviet_merlin · Posted

      I wonder if there is much to tell without knowing where the bolts where bought from. If it comes from Amazon or similar all bets are off. Can't trust them. And I fear not everybody knows that. Wasn't it @TurboTapin who ended up with the fake fuel lines recently? The submersible ones which very much weren't submersible at all. It kind of applies to everything nowadays. Doesn't matter if it's hardware or electronics. The fancy camera might have internals swapped out for cheap knockoffs. The hard drive will report a certain size but not actually be able to write it all. Shit like that. A bit depressing but the reality is you really have to be weary of where and how you buy stuff

      My guess is, cheap rods, came from a site selling lots of cheap things, and likely a lot of knock off stuff.   I get doing a cheap build, but I don't get doing a huge dollar build, and then skimping on something even like the rods, and likely the bolts to go with it, especially if heaps of stuff had to be fabricated!

      Got this r31 silhouette flood car to rebuild.

      Today myself and a mate tracked a fuel pump issue down to this amazing piece of workmanship in the fuel cradle loom. Covered by conduit and electrical tape. so now we should be moving onto the first fire once this is corrected. 🤞🤔

      1000% percent the looks just aren't visible, I was shocked when i found out the the only thing holding the OEM diff ( rear side ) is one stud was can easily crack when trying to launch the car or really beating on it, hence why this brace connects to the subframe/control arms and even includes a fancy jackpoint, With the forced induction route, I would have quickly launched the diff out the back of the car without this upgrade. The Z1 and GK tech don't offer the same "cool" look so to speak.
