WOW!! 35 views & not a single reply!!

the reason am asking is, i can get exedy parts here coz there is a dealer here, but have to order OS parts so that takes time...

Yes I believe Exedy can make new clutch plates for the OS clutches. Sorry I have never had it done.

I was told it's the cheapest option though.

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.

ah. Just realised you are not in australia... Still, just order the bits, no problem there.

Exedy are the OEM for OS Giken, plus about 10 other jap companies. They seem to just anodize bits and call it a new product.

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:
