MT90 Redline ---Additive?

[Christopher Seabert]

Hi guys I was lookinf in the history and I know MT90 is pretty much the
choce here for our trans.  But the thing I have not found or I might just be
blind and confused is that when we use the MT() do we add any additives for
our LSD or no?  SOme people I have read they put the LSD additive in and
somepeople say it is not needed because the LSD is sealed. Please anyone
what is true? I am going to install a ACT clutch in a few days and I need to
know if I need the Additive.  Thanks alot guys:)
