I found someone who did a 1UZ-FE to BMW flywheel, as it’s the same diameter as the 01E clutch I was planning to use, with some measurements I figured it should work and save having to make my own.

I obviously need a pressure plate but that should be straightforward.

Now the only question is over the clutch disc. Do I go for sprung (noting obviously that this *actual* clutch plate is dead and I’d need a new one)

Or unsprung (brand new clutch plate but only cost me £10 so I’m not too concerned about throwing it away).

My thoughts are that it should be sprung, on the basis that in the original fitment for the unsprung disc the car was fitted with a DMF which would have been sprung and the RS4/S4 etc are sprung (as well I believe still fitted with a DMF).
