B5 S4 Clutch/Flywheel For 3.0?

So I’ve read around the internet that you can use the S4 clutch and flywheel for the 3.0.

My 3.0 is starting to have clutch/flywheel problems so I am looking for the best options. EuropaParts has a kit (http://www.europaparts.com/clutch-conversion-kit-52405618-valeo.html) and it seems to be the most economical. My 3.0 is stock, but I would like a little better performance from it. Wouldnt a SMF reduce rotational mass, thus letting the engine rev faster?
