What about lightening the flywheel, has anyone done that when replacing the clutch in there S4?
I know this is a pretty common task when replacing the clutch. It improves reving and decels. I did it in my Urq and shaved 11lbs of rotating weight.

So with your RS4 clutch. Did you also use the RS4 pressure
plate? Where did you get them from? I have seen AWE sells the
kit, but I was wondering about just ordering the needed part
numbers from Claire Audi. They are usually pretty cheap, but
my fear is that there could be parts needed to adapt the RS4
clutch/pressure plate to my flywheel. I do not plan on
replacing my flywheel.. Unless I have to. I have also HEARD
that the RS4 Clutch disk is actually the same.. its the
pressure plate that makes the difference. ideas?
