I cant imagine you arent talking about the FW in my car and a few others.
Seems a good unit and windup in 1st thru 3rd is much quicker and revs drop
much faster. About the clutch, it wont hold much over 360hp if driven hard (I
cant do a hard shift in 2nd and it slips a little in 3rd as well), a much
better choice is the sa603s by SPEC clutch, holding up to 600hp and with good
driveability. I am having one installed in January b4 dyno runs and will give
results. It was virtually guaranteed to hold full throttle launches, if the
shafts dont twist into or the crank breaks. The flywheel isnt what causes the
vibration either, the clutch disk used in the centerforce isnt sprung and
this causes the vib.., this accd to MTM via another lister who bought their
1800$ rs4 stuff. The sa603s has a sprung disk and should be quiet, also the
SPEC can be balanced and the centerforce cannot. Good flywheel, word on
clutch after Jan 7th. Price on SPEC clutch is 460$.
