You are just about there now -------------- unless I missed
something.
It didnt take much to get to the 11's then the 10's.
a bit more negative toe-in in front and positive toe-in front adds
more stability. go up on the front sway bar a bit for more
understeer, add a pound or so in each tire, and juggle the camber
settings to give a better contact patch and I think you will see 11's
easily.
As a side note -----------------
The Ferrari ------- I have found --------- is SUPER sensative to
tire pressure changes. One pound of pressure can make WORLDS of
difference in the handling and swaying it seems to possess.
