I'm going to sum this up quick.
Do not use an Aluminum flywheel in your AWD DSM or EVO
unless you want to have problems. I have never
recommended them nor will I warranty damage to your
transmission from their use.
Aluminum has roughly half the material
strength of steel.
Aluminum looses roughly 33% of it's
material strength when heated above 370*F.
they are too flimsy for the task of
being a worthy flywheel in an AWD application.
if Aluminum flywheels were so awesome
then why hasn't the other flywheel manufactures making
there is no deal you can make with
Jesus or Satan to keep that steel friction ring flat, it
will warp and cause poor shift quality.
The only flywheel that I recommend for
the AWD vehicles is a SFI approved Chromoly flywheel.
