Awesome one is a SMF conversion by ECS with a SACHS vr6 clutch, also weighed down to 14lb. Stock flywhell is DMF and 20-21lb. They do the same kit in 21lb if you want a heavier flywheel.
I have it fitted on mine and its a good bit of kit, plus replacing the clutch on SMF should you wear it out again is a hell lot cheaper. Plus the vr6 clutch is rated around 260lb/bhp.
Common complaint with lightened flywheel is the juddery driving. But having one on I say its not juddery at all and it is still fine for daily driving, no different than stock DMF except a lighter clutch pedal with SMF.
