Yes it does, and not much noise because of it.

What's involved in lightening a flywheel? apart from getting a machine shop you trust to shave a few kilos off it, do you have to get the thing balanced to your engine afterwards or just swap it over when you change the clutch and drive off with a big smile on your face?

Cost me $100 to machine and balance at a local speed shop. Swap it.

M42 clutch and pressure plate works with the M40 flywheel without mods.

Only the non-AC clutch assembly will work with the single mass flywheel. AC cars have the dual mass flywheel. Totally different clutch used on each model.

How much is the M40 flywheel? I know JB racing sells a sprung-hub aluminum flywheel here

For all the people who would like a lightweight flywheel for the M42, I'm suprised that there aren't more options...

Keep an eye on e-bay. I found mine for $50, $25 shipping. I've seen others since then.

I've a quote for about �60, but they say they need the crankshaft to balance it - didn't realise this -do you need to remove your crank for them so they can 'run it on the balancer' :confused:

^^ sounds like a bit of BS to me, one of the machine shops I talked to said that they have a machine that more or less "simulates" having a crank hooked to it.
