twin disk questions...
Bought a used twin disk and it looks to be in great shape. Can you supply the specs for the disks so I can check wear to see if they need to be changed.
Thanks
Thanks

You can't buy new organic discs. You have to get them resurfaced. I got mine resurfaced. The material that was used for mine was was .125" material on both sides. With an overall thickness of .308. I would expect new to be somewhere close to that. The rivets take up a decent amount of that material too.

Organic is hard to drive on the street. Ceramic is impossible. I love it. The shifting is ******* amazing. Would not run a ceramic on the street. Organic is hard enough already.

The flywheel is so light and the MOI is so small that it takes getting used to. I've had it for a few months and I still stall every few times I drive it.

^^good to know. Mine didn't have that problem, but I also had the flywheel turned. Just scuffed up the floater plates though. Couldn't have them turned where they did my stuff.

Speedsport probably would have been a better choice for the intended use. Clutch was magical, not as hardcore as the 949 MOI wise but stupid easy to modulate without much pedal pressure and didnt mind if you totally nuked it. I have no idea why they made a steel street version of that clutch the one that was like a pound heavier than the 949 was easier to drive in traffic than the oem wrx clutch. They dont seem to be in business any more.
