Yes. The owner was adamant nothing short of a 10" diameter AP racing twinplate clutch was up to the task. So we made it work.

I'm not a fan of using a push clutch where there are plenty of good options that do not involve re-inventing the whole release mechanism. As I said earlier, the pull to push mechanism is far from elegant. To me, they (ORC, OS Giken etc) already had twinplate clutches already in their catalogue and they simply manufactured a flywheel to suit a Subaru and an adapter linkage to make it (sort of) work.
