Clutch Masters Twin Disk... any reviews?

[thor'svr4]

Ive been debating picking up a clutch masters twin disk 7.5" but couldnt find any reviews. I noticed Austin from STM had used one in the past, but couldnt find any other info. Is anyone on here running one? Im worried about setting the clearances since ive read they dont come with any instructions for shimming.

Anyone have any info/reviews?

I own Austin's old one. I haven't run it yet but it is pretty damn nice and looks to be made great.

He ran tons of passes with it with no issues.

I don't think you have to set clearances, because our setup doesn't have an internal slave cylinder. I could be wrong. Mine doesn't have any shims with it... I also haven't installed it yet. That will happen this summer/winter.

I will keep an eye on this myself. Great reviews from the supra guys.

Why not the O.S. Geiken triple disc?

I also don't think you're supposed to shim it. The clutch kit comes with a modified TOB similar to stock just a little different. If we had a hydraulic TOB I'm sure we would have to shim it. I have the 850 kit with a street and race disk setup but I haven't installed it yet. I don't expect it to underperform. If anything it may be a little noisy on engagement but the pedal effort shouldn't be much more than stock.

Hydraulic TOB is what I was meaning to say, not slave cylinder.

That's why the supra guys have to shim. Our pressure plate/TOB pressure rests on the clutch fork, so no shims needed

Alright some good info here. Knowing that i dont need to do any shimming definitely makes me feel better about purchasing one. Has anyone actually installed there clutch?

Ive considered the OS twin disk but wasnt aware of the triple disk

I run the OS Giken R3C, don't think you could ever get this to let go!.

Had a centre hub so all the discs drive from the hub, the hub drives the gearbox input shaft.

It's a thing of beauty, shame you can't see it under the bellhousing..

I thought a few people had issues trying to drag the OS Giken triple clutch?

That would be a bit strange, I know that Quartermaster produced a gear drive version of their twin disk from higher torque Evos and DSMs wearing out the input splines IIRC. Not sure how similar the OSGR3C is, but if anything like the QM arrangement, should be able to handle it without problems. The QM gear drive with a HTOB is the eventual plan for my twin disk flywheel based on what the Evo guys have seen.
