new clutches
i have a general question in regards to oem clutches.
i'm in the process of getting a new clutch, it's lasted about 92k and with the rs4 clutch it's gonna cost over $3000 in parts alone, the main cost is the flywheel.
apparently you cannot machine the flywheel as it's a dual mass flywheel and there aren't any machines that can do it, so that leaves me with having to look at aftermarket lighter ones.
do lighter ones really make it that much more different to drive? or does it mean you just have to learn to drive it differently? apart from it revving more freely, is there any other differences, negative or positive with a lighter flywheel.
thanks.

yes they told me to ask aus coz he knows most things about cars and stuff.
i got some answers anyway, but i thought i would get an opinion off some other people from a non-european motoring background.
apparently dual mass flywheels with rubber mounts cannot be machined properly, therefore, when you change your clutch plate, it is advisable to change your flywheel as well. that is why european cars are so damn expensive to maintain, little things like that which add up which is just crap.

I've also heard that some manufacturers want the dual mass flywheels replaced with the clutch as the elastic materials in the flywheels have a limited life. If the material starts to delaminate it can result in engine vibration and damage to the crank bearings. Unlike the harmonic balancer on the other end of the crank, a dual mass flywheel is harder to replace.
For those who dont know, A dual mass flywheel is simply a large harmonic balancer. The outer mass of the flywheels is suspended by an elastic/rubber section from the centre of the flywheel. It helps dampen out vibration and torsional harmonics in the crankshaft. Think of a turning fork with a lump of bluetack on the end of the forks.
