And the lightened ones are around 6-7 kgs ?
Also, what do we think the gains are? I was told 20-30 ft/lbs of torque ?

Do they all chatter? How refined do they get?
What are the gains typically?
What sort of cost are we talking?
What is the effort to fit and what sort of additional effort are we talking if you were already replacing the clutch?
Anyone had a lightweight flywheel on a K03 S4?

I have installed a few Fidanzas. The engine revs more easily, but I haven't noticed so big difference when driving (haven't done any logging, just normal driving). Of course it helps, when it's more than halve the weight of the original.
It doesn't give any more power or torque, it just "releases" it from the engine. (if you don't change the boost or timing, how could it anyway...?)
One Fidanza is now on eBay, 165£. Those are quite cheap, but those work ok!
Installation is quite easy when the clutch is out, but those bolts have to damn tight when installing. You just need some muscle

Having decided to go the K04 route I now have a slight obsession with lag and response so I am looking at reducing mass where possible, and within a budget that doesn't make me whince too much.
I have been looking at the 034motorsport steel flywheel that comes in at 15lbs. It's a couple of lbs heavier than the aluminium wheel but should suffer less chatter. However it does not work with an RS4 PP and would requires a Sachs or Spec alternative. We are talking about a grand landed cost
